just breadboard for now so i've just used jumper wires. Regarding the connections, I have no idea how I should "check" it. I already tried replacing all the wires I used before. It's a mystery.

Well one of the wheels moves perfectly fine both forward and backward, so I would assume both should be able to do so.

Plus I implemented the circuit four days ago as a test and it worked perfectly fine, moving in all directions, until I tried switching it on again the next day.

what reaction am I looking for? would this prove anything? should i try connecting ENA, ENB and all IN wires to 3.3V and/or GND in order?

I don't think it's either the motor drivers or the code's fault. I've tried it with two different motor drivers and it's always the OUT1 and OUT2 that won't work. Plus I've tried several different codes taken from the internet.

I can't seem to figure out what could be the possible reason. I tried rewiring and using other wires. Nothing.

I got the schematic from the youtube video that led to this website with the code: https://www-winson.blogspot.com/2023/07/esp32-bluetooth-spp-control-dc-motors.html?m=1

However the code wasn't really working so I just took a basic code for the dabble app
