Re: Raspberry 3 B+ Car with L298N tutorial/setup?

just were a bit confusing and I thought that 1 motor should turn, Although you prefer pictures to words, it might be useful to confirm that this is not what the documentation specifies: From https://gpiozero.readthedocs.io/en/stable/api_boards.html#gpiozero.Robot left(speed=1) Make the robot turn l...

Re: Raspberry 3 B+ Car with L298N tutorial/setup?

The test wiring was for one motor only if you want to test both motors you need to connect IN3 & IN4 in the same was as you did for IN1 & IN2. If only one motor is working when you connected it to the pi then I suggest you check your wiring and you have it connected to the correct gpio pin. Hey, I ...

Re: Raspberry 3 B+ Car with L298N tutorial/setup?

As we don't know what voltage your combination of batteries is producing at the moment we can't say if using new batteries would help , that's why a volt meter would help then you could measure the voltages present in different parts of the circuit while its in operation. Finding the cause of your ...

Re: Raspberry 3 B+ Car with L298N tutorial/setup?

Right then before you can go any further with trying to figure out what is causing your problem you really need to invest in a digital multi meter. It does not need to be anything expensive as you are only working on low voltage DC. This is a cheap one I have sitting on my work bench. https://i.img...

The LED is coming because the input voltage is dropping due to the load on the battery.

But is the motor turning ?

Again I will ask Do You Have A Volt Meter ?
No I dont have.
and it doesnt turn.

Re: Raspberry 3 B+ Car with L298N tutorial/setup?

Then the problem is with the motor driver board. Do you have a meter by any chance ? and can you post a picture of your motor driver board so I can see the board in detail to see what pins/ terminals it has exactly. take the picture from above so it looks like this https://i.imgur.com/OMnayOZ.jpg h...

ok simple test. Disconnect the wiring between the pi and the motor driver board at the pi end. With the battery connected and the LED on take the wires connected to IN1 and IN2 and connect one of them to the ground terminal on the motor driver board and the other connect to the 5v terminal on the m...

gpiozero uses BCM numbering for the GPIO. Are you connected to the BCM pins 7, 8, 9, 10 as shown in https://pinout.xyz/ ?
you mean the GPIO 7,8,9,10 ?
if yes they are connected


in1 = 7
in2 = 8
in3 = 9
in4 = 10

You can use any of the physical pins #9, 25, 39, 6, 14, 20, 30 or 34 on the 40-way header. Do the motors run when you test them with a bat...
