Subtract that from your supply before you start, that is a big hit in low voltage systems. That is a total of 4 junctions yielding a drop of 4 * 0.7 = 2.8 Volts.
L298N MOTOR DRIVER BOARD ARDUINO SKETCH SERIES
This places two junctions in series with each motor lead. You have two configured as a darlington configuration on each output. Through a silicone junction it will drop 0.7volts for each junction. Since they are transistors they have a PN junction. I will see if I can help but no guarantee. In your spare time read some materials on basicĮlectronics.
Why shouldn't i use AA batteries? does anyone please think they know the solution to my problem? thank youĪlso should i change my use Li-ion battery 18650 x2 instead of the 6LR61 9v battery i used so i checked other tutorials and saw people using AA to control 1 or 2 motors. 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 ( ) to not use AA batteries but no explanation why. 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. 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 thought my connections were bad so i redid all the connections but it didn't work so i changed the battery to 9v. initially it worked but then a few minutes later it stopped moving.
i connected 2 of the motors in parallel so i can use 1 L298N to power it on. 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'm trying to build an Arduino 4WD smart car.
