After the disappointment of trying to use the 28BYJ-48 as a drive motor for my robot, I purchased some DC Gearbox motors from Pololu to use as drive motors. These motors are a bit pricey at $36.95 each, but they are powerful, and have built-in encoders for monitoring the rotation.
I built a test circuit using a L293D H-Bridge integrated circuit. My initial circuit was quite simple. The L293D has 2 independent H-Bridges which can control 2 motors. Each motor has 2 inputs which are signals from the controller. In my case, the controller was an Arduino using PWM (pulse width modulation) outputs. The chip then has 2 outputs which can drive the motor using a high voltage, high current source, VS, which can be up to 36V according to the data sheet.
can you please give any details on how to drive pololu dc motors with encoder with l298n using arduino and its code.
