L298N motor driver and battery issues I'm trying to build an Arduino 4WD smart car. so i connected my l298N motor driver module with my v4 shield and used a 4 x 1.5v AA batteries to try and power my 4 motors up. i connected 2 of the motors in parallel so i can use 1 L298N to power it on. initially it worked but then a few minutes later it stopped moving. i thought my connections were bad so i redid all the connections but it didn't work so i changed the battery to 9v. with this the motors worked for a few seconds then stopped but was making noise so i tried powering the motor driver with my Arduino but it didn't come on. I tried powering the motor driver module with my Arduino but the driver module didn't come on.i decided to use my bread board and l293D IC to control my motors it didn't work but the motors were making noise. I changed my motor to one that i removed from a PlayStation controller but nothing still.i did research on the internet and was advised on this tutorial (https://create.arduino.cc/projecthub/maxxlife/arduino-4wd-car-cf5fd0) to not use AA batteries but no explanation why. so i checked other tutorials and saw people using AA to control 1 or 2 motors. Why shouldn't i use AA batteries? does anyone please think they know the solution to my problem? thank you
This is how my kit looks https://www.ebay.com/itm/NEW-4WD-Robot-Smart-Car-Chassis-Kits-car-with-Speed-Encoder-for-Arduino-M26/201561877173?_trksid=p2047675.c100009.m1982&amp;_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D36860%26meid%3Dc76077722d4348e88152fa6c7f32c005%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D181329341315
Also should i change my use Li-ion battery 18650 x2 instead of the 6LR61 9v battery i used
Rule #1 9V batteries a power supply they are NOT. In your case you are looking at small voltages for the motor power. Your choice of a driver is not the best as you will have from 1.2 to 2.4 volts across the L298 depending on the loading. This is directly from the ST data sheet. Try the TB6612FNG instead, taking advantage of the device’s use of MOSFETs. The TB6612 may be a little more expensive, but it will be clearly worth it.
