I have something better coming up that I played around with last week, better motor driver and PCB board, The L298N has a high voltage drop not super great

Great video, quick concise. Thank you

my pico won't active the power out of the controler for the TT motor, but powering the input 1& 2 with 5v and ground will make the motor spin, how do i get my pico to activate the motors?

@NerdCaveYT

7 ай бұрын

I am a bit confused are you power the driver with a separate power source, the pico won't be able to power the motor driver, The motor driver can deliver 5V output which you can connect to pico to power it, but then you can't have USB plugged into the pico.

Can I control a servo that module? I want to make a roof open and close witj a rain sensor module and one servo that open /close when rains

@NerdCaveYT

It depends on the size of the servo and the current that it will draw, there are other more effective motor driver modules then this L298N

Thanks, I've been trying to do this , but with just using the IC. It works fine with the arduino uno, but when I plug the same thing into the Pico, I get nothing. I check the pico pins with an LED and there are signals coming out. Any ideas?

@@NerdCaveYT thanks. I got it working. The issue was that the 3.3v from the Pico wasn't enough to power the ic. Had to use the other supply.

i have a wierd problme, the driver can control one motor fine but not both, each motor works fine individualy put when both plugged in only one workds

That sounds strange so when the left output works and right output of driver but once you run both it does not, could it be possible a code issue? Do you have a multimeter to check to voltage level that might be that there is to high of a voltage drop from the driver and you might want to increase your PWM if you used it

It's alive, thank you dude...! ~ I'm using four 2A batteries for powersupply, and sometimes there's only beeping sound (and the correct LEDs) from the L298n...! Is this a powersupply issue...?

@NerdCaveYT

Жыл бұрын

Is the beeping sound coming from the module? I have not encountered that before. I know if you use the PWM and you do not supply enough voltage to the motors it will give of this high frequency buzz sound.

@@NerdCaveYT yeah, it comes from the module, not the Pico board...!

I have a question, how do i control the speed of the motor normally? i've tried using PWM for the enable pins, and setting the duty cycle lower, but that didn't seem to work. I am not using a joystick, and just want my code to be like the first example, but with speed control. Thanks!

@NerdCaveYT

7 ай бұрын

Only way to do speed control is with PWM, now if the PWM duty cycle is to low, the motor will not receive enough power to make the shaft turn and you should hear a high pitch frequency noise, and as you increase the duty cycle it will start to turn. So with button controlling the speed make the duty cycle to a point where motor turns then you can use a button to increase or decrease the duty cycle to control the speed. Also a side note the L298N even though very common motor driver it is not as efficient as the alternatives. I will next week make an update video with a different driver the drv8833

Hello In your video you feed the pico through the usb socket. can it be powered with the LN 298 card? if yes how? otherwise how to power the pico other than through the usb socket?

@NerdCaveYT

7 ай бұрын

So I mentioned in video the LN298 does have a 5V output which you can plug into pin39 of Pico to power if the USB is not plugged in, both should not be plugged in at same time, so when programming the Pico do not have power connected from the motor driver to the Pico.

@@NerdCaveYT Thank you very much for your answer. Another question, is the voltage supplied to the LN298 board lowered when it reaches the engines? If I power the board with 7.4V I will have how much power to the motors?

@NerdCaveYT

7 ай бұрын

@@pasquentmax If I remember correctly there is a high voltage drop like 1.6V or somewhere in that range, the LN298 is not a great motor driver, I used it because had a few laying around, recently I made a new design for the DRV8833 a custom PCB which I will probably upload next week

if you connect the board to a breadboard you can just use normal wire then, network cable works well or just anything that works with breadboard if you have no breadboard then directly soldering wire to pins
