Hello Mario, First, great Video! Thank you. I just brought this Coin Acceptor after I watched your Video and today I played around with it. I'm working on a Cady machine for Kids (ofc not for permanent usage. The Kids need to do different Task like collecting trash to get a Coin. It's for an event). So, I trained all my Coins and connected a LED between Ground and the Counter Pin, that was working as expected (Blink Whenever a Coin is inserted and also in different repetitions). But when I connected the LED to Ground and Coin Pin, it just turned the LED on even tho it's on Normally Close. I expected a Consistent Blinking like a Clock where I can Orientate the Counter Pin to. My plan was to use 2x optocoupler. I'm not new in Programming but I'm (very) new to electronic and to be Honest, I didn't understood that much when it came to connection. It seems like you connected the Coin Pin directly to the Arduino, in my Case it would Fry my ESP8266 or I am wrong (that's why I also wanna use optocoupler)? I don't understand, I hope someone can Explain me this in a way that every dummy will understand this.

Really a great video. Greatly explained 👍

Well. I cannot write the code for you. You need to introduce one or multiple buttons and write the code for them.

I remember working on one of these but at the time there was something finicky about it (output value? i think cant remember this was years ago) anyhow had to solder wires to the 6 leds to get the correct feedback rather than detecting the usual impulses, i think its because the impulse were too slow when the user inserted coins quickly and therefore you get mixed of impulse. Like if I had a quarter that had 5 impulses but then I inserted another coin While those impulses were still sending out, I'd get higher amount of impulses. This additive feedback isn't practical for real world usage.

@erickroeger1161

Ай бұрын

@@NicodemusTSo pules aren't at all reliable because they add on top of each other due to the fact that they're being measured by the m/s (or whatever); this is why, for example, when you insert a penny (1 pulse) and QUICKLY insert a nickle(2 pules) you end of with 3 pules as an output. Its a bad design because your essentially working with one variable when you need 6 distinguished variables for each coin. (idk about the 12v thing but) You'll can hackishly opt to detect the voltage change in the leds themselves by soldering a wire to the pads and use that to distinguish which coin was inserted. Mind that this was a long time ago I can't remember much working with Arduino but maybe I can dig up some links I found; if I can I'll post again later if i find them.

Well I think the coin acceptor is ok. I had rare issues when writing the initial code where a single impuls was resulting in runnig the interrupt function more then once . I realised that after filming the footage. This led me to introduce variable "i" to eliminate this. I reshot some of the footage after that change.I had this issues with interrupts on other projects. Now I cannot tell you if the use of "i" did not fully eliminate the error or I used the previously filmed footage that contain the error . Now , knowing more I would do it differently. I would use millis() inside of interrupt function to make sure there is proper time interval between impulses. I already used in my other videos. e.g. kzread.info/dash/bejne/a5Vp04-xdNnAgdY.html go to 4:55

@@marios_ideas Therefore, I do not use sw arduino, but I write in assember directly. It is very fast and reliable. The point is to measure the time it takes for the finding how long pulse to last after the interrupt is triggered, as MCU can also find some short-term interference as a pulse and it has a short length of log0 (less than 90mS). Consequently, if the pulse (log0) lasts more than 90mS continuously, but a maximum of 110mS (according to the validator setting to 100mS length of one pulse), then the length is checked for how long it lasts (log1) and only then it is decided whether it is 1 pulse in this in the case of a € 1 coin or a further decrease to log0 continues and it will be 2 € 2 pulses, etc. Everything is decided no later than 110mS after the end of the last log0.

After a hiatus, I have come back on working on this. I just recopied the code, and readjusted the pulse counts and total amounts to reflect my needs. i.e. if (i>=30 and impulsCount==2){ total_amount=total_amount+2; Looking at the serial monitor, I can see the total pulses being counted, but the variable "total_amount" is constantly staying "NaN" even before a coin has been inserted, though I do see you have total_amount already set to 0. This means the display goes to 0 when turned on, and never changes from 0. Any ideas on this?

Like in this video 2€ - 1 pulse, 1€ - 2 pulses, 0,50€ - 3 pulses etc. COIN-pin pulses are to determine how much money has been inserted and COUNTER-pin pulses how many coins have been inserted (not sure if it counts all coins or only accepted, probably only the accepted)

Same 2 coin use to 1 puls, is it possible

@marios_ideas

Generally it is possible in two cases: First one is if your code is not properly counting impulses. In my code I assumed the impulses are lass then 30ms apart if I am not mistaken , if your device has a different interval. Some have even a switch to control that interval. Fast midum and slow. If code does not correspond to the actual device setup then you can imagine two impulses are interpreted as one. The other case maybe if the learning process was not properly performed e.g you did not use the right sample amount or cheated the process by using the same coin over and over again and you have coin types that are similar. Then the device maybe confusing the types.

I had also bought a special device which converts the pulses to serial hexidecimal, but it seems to be a bit over complicated, and lacking the ability to connect the coin counter. This Adruino nano makes it a much better choice (and cheaper). Thanks for putting this up.

Does this work with LCD DIsplay I2C Module ?

The dopłat is used just to display the total. Any display can be used but the code would need to be adjusted. I have not used LCD in the past but i do’t imaginacji this would be complicated. Just a change to few lines of code

Connectity like here: howtomechatronics.com/tutorials/arduino/lcd-tutorial/ You do not have to connect potentiometer Then in code: #include // includes the LiquidCrystal Library LiquidCrystal lcd(1, 2, 4, 5, 6, 7); // Creates an LC object. Parameters: (rs, enable, d4, d5, d6, d7) in setup function lcd.begin(16,2); // Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display } And the replace if(total_amount

in the in the incomingImpuls function shouldn't there be a "i = 0" above "impulsCount=impulsCount+1" too? that way, it doesnt read the first impulse as only 1 and add the value you set for 1 impulse?

This is one major problem with this code. When I was writing it I was not yet familiar with millis function. The use of i variable is a workarund . each time impuls is detected we reset i to 0 in the interrupt function. Then i gets incremented in the loop function. If we have multiple incoming impulses they are close apart. Inbetween each impuls the loop function is executed less then 30 times and we keep increase impulse count. If all impulsess I read then Loop gets executed more then 30 times and then we know there are no more impulses and then we can positivly finish coin recognition process. If I used millis I can meassure the exact interval between impulses and this way I would not need I variable at all.

@@marios_ideas do we know the cycle time of your Arduino to get a feeling what these 30 times trough the loop stands for or even better do we know the exact interval time between impulses by now?

​@@4x4Tobi When I was creating this video I was not familiar with Millis function. This can replace this whole thing with counting cycles. Check my millies tutorial and you can then check the video I created for Eggtimer where I use millies in the interrupt functions to make sure I am not reacting to a single button press twice. This is the same concept I would use in corrected coin acceptor code if I was writing it now. I will be creating some Q&A videos and I may include it in it providing corrected code.

Can you do a coin counter using a coin hopper?

Is this the device where you have different slot sizes through which coin drops and this way it gets recognised? I have many projects already planned so even if I will look into this one it will not be in immediate future

Connect LED e.g. to PIN6 #define LED 6 In Setup pinMode(LED, OUTPUT); digitalWrite(LED,LOW); And then in Loop function if(total_amount==2){ digitalWrite(LED,HIGH) You can connect anthing to this pin. E.g. magnetic lock.

I have a separate tutorial on this. #define LED 6 long Timestamp_2EUR=0; // records time when 2EUR was reached In Setup pinMode(LED, OUTPUT); digitalWrite(LED,LOW); And then in Loop function if(total_amount==2){ digitalWrite(LED,HIGH) if (Timestamp_2EUR==0) time_past=millis(); // if Timestamp_2EUR is 0 means we just reached 2EUR so we record the timestamp // if it is yet another loop run with 2eur reached Timestamp_2EUR is not changed } if (millis()-time_past>300000){ // 300000ms is 5min. We check if the 5 min was exceeded digitalWrite(LED,LOW) // LED off total_amount==0 //reset the balance

Weel. you overrate my skills. I would be able to build a simple vending machine but hacking into existing washing machine to introduce coin acceptor is much more complicated

@MSIUser2012

I am not sure what exact functionality you want in this control box, but a simple idea that can make integrating this coin acceptor with an automatic washing machine. - You can use a relay module with the Arduino and coin acceptor to turn on the washing machine. For example, to use the machine, user must insert 50 cents in the coin acceptor. Once the coin is inserted and it is equal to 50 cents, then the relay is triggered and the washing machine is turned on for an specific amount of time. After that time passes, the washing machine will automatically turn off and the coin acceptor will reset the amount to ZERO. Again, this is just a simple idea and I haven't tried it practically. But I hope it would help.

Where is the arduino receiving power from?

@marios_ideas

8 ай бұрын

In the video if I am not mistaken I was powering Arduino from USB port of the PC or from the powerbank. However if you want to have a single power supply then you need 12 powere supply which powers the con acceptor but also connects to VIN and GND pins of Arduino. VIN pin is regulated down to 5V. Caution. Do not connect 12V to 5V pin as this will positively fry the microcontroller.
