Hey buddy, I don't always reply, even hardly at all. But I do want your videos and I appreciate the efforts that you put into them. I just wanted to share with you that I used one of your projects on my wood stove That heats my house here in Colorado, USA. I live about 7,000 ft. winners get bitter cold here. Of course you know that being in Canada. When the wood stove approaches 150° F it turns a fan on. I use an Arduino and a high temp reader. I believe it goes up to around 1500 or 1600. I can't remember the type of high temperature reader I use. I have to go look it up. But I wanted to thank you for that. I may incorporate this PWM speed control into my last year's project because I always don't need the fan on high. Thank you robojacks You are brilliant.

And you know what else, that fan system has been powered on and been in standby since the end of winter. It's been powered on since last September or October. It still gives me the temperature reading, usually in the '70s this time of year. It hasn't locked up. It just works. I have the electronics in an eyeglass case with wires hanging out. I need to look around and find something a little more suitable. One thing I would like to correct but not sure how, when the stove reaches 150, the temperature will fluctuate between 149 and 150 it goes back and forth quite a few dozen times as it cools off. This causes the fan to kick on and kick off. It's kind of annoying. But it's working exactly the way it was designed. It's almost like it needs a threshold, or it needs a timer built in the code to wait a few minutes before turning the fan off. I'm not sure how to do that. I also haven't looked into it.

Hey, thank so for the comment. to fix the fluctuation of temperature in arduino, it is easy. let's say the variable holding temperature is "temp" and you want to take action when the temperature equal of above 149 AND equal or less than 150, then use if (temp >=149 && temp

Helpful video 👍 I like it

Getting closer to what I asked for last year...need to control 12 VDC motor speed based on thermocouple input to Arduino. Thanks!

Love this Hack with voltage controlled by ardunio, i've learned so much watching your videos... thanks !!! .... I got a question... In you opinion , is this the best unit to use to control voltages with ardunio up to 3a... .. say input is 12v, output from 0 to 12v... or is there some IC I could use... the smaller the better.. for loads from 1 to 3 amp lets say ... your advice would be much appreciated..

You are welcome. I am glad you like them. This module is being controlled using PWM which does not change the voltage. Actually the motor speed is being controlled by the duty cycle or the at that interval and for how long the voltage is turned ON/OFF. so the voltage stays the same. This method can't be used to control a power supply. I have this application on my list and I will God willing make video on that.

nice video, i have project to control 24v 10a dc motor, it can foward-reverse, so i want to use bts7960 as motor driver, but i do not want to use arduino, can i use this 3a pwm controller as input for L-PWM or R-PWM in bts7960?

The module just needs PWM doesn't matter from where. Yes you can sue. I will reply to all Subscriber's 🔔 questions. So make sure to Subscribe.😊

Hello, I had a question, after cutting the connection between the 555 timer output pin 3 and the is it possible to connect the output from pin 3 to arduino's digital pwm pin and back via another pwm pin in order to read the pwm signal from the LM555 and then create limiting conditions on the pwm using the arduino's digital write pwm signal pin and feeding it back to the output 3 ?

You can read PWM using Arduino but it needs a little work like frequency and duty cycle. Do a Bong or google nsearch

What is the frequency this module works at? I would like to control a servo motor with it and the servo motor works with a pwm at 50 Hz.

Hello Sir What an interisting hack that you did. I wonder if i can control the speed using hall sensor magnet, so if any pole side of magnet geting closer n closer, the more speed we had. Can you figure out the value of hallsensor in map? As we know the value of potensio in map is 0, 1023, 0, 255. Or maybe someone can tell me the value of hall sensor if I change the potensio with it. Best regarads and million thanks before

Does it reverse it too with negative values?

@@robojax I watched it, great durable controller. But my question is, can we control it with arduino forward and backward? In arduino the value of 100 runs it forward. Will -100 (negative value) run it backward (reverse)?

Can this use nodemcu?
