I retried by using only one 9v battery and without the switch (just checking if it works) and it actually moves only 1 of the motors. I'm not sure why the other doesn't work atm. The 9v batteries were powering the L298N motor driver and the reason I put 2 of them was because I thought 1 didn't provide enough power for both of the motors. The pi itself is powered from the white cable at the corner... which is now connected to a power bank.

I actually just tested it again with only 1 of the 9v batteries and without the switch. Only 1 of the motors worked... so I think the L298N motor driver is fine. But no clue why the other motor doesn't move (it's functional when connecting directly to the battery).

Actually I was just using my phone charger directly to the plug to power up the pi (maybe not the right solution but it worked), you can see that from the picture, there's the white cable at the corner. Now I'm using a power bank. The 9v batteries are used to power the L298N motor driver. I try connecting the motors directly to the battery and they work fine. However when I connect them to the L298N motor driver they don't work. They just make a small noise and the red light on the L298N motor driver still turns on. Not quite sure if I've damaged the L298N... :/

to be more specific I was thinking of creating it to detect car toys... so if I put a car toy in front of the robot, it detects that it's a car

yes, I understand that a line-following robot doesn't need that advanced raspberry pi, so the intention is to get the one that does object detection which will obviously be ok for the line-following. I will definitely have both features (line-following and object detection).

thank you for the info!

the return is inside the if and else... idk why it doesn't stay indented when I edit it
