Hello everyone
I'm trying to build a small radio controlled car that has the ability to bypass obstacle.
I'm using ultrasonic sensors k3502 parking sensor as an eyes for the car. The ultrasonic will provide an audible sound that will be interfaced with the interrupt port in the ATmega8535.
The problem is I'm using L293 motor driver to drive the DC motors but the car struggle when moving. I'm using a 4.5v to supply the microcontroller which will supply the L293 motor driver which supply the DC motor. And for the sensor another source of voltage.
Is the concept I’m using is the prober one? Or there is another effective and reliable ways.
