Can I control a bipolar stepper motor with an L293d motor driver shield using HC-SRO4 ultrasonic distance sensor on arduino?
Yes, you can, they are completely independent, but that does not mean you can use e.g. an Arduino Uno to do the following:
- Read the sensor
- Based on the sensor values, control the L293D
In case you have doubt how to start, I suggest the following:
- First, only use the HC-SR04 sensor (build the circuit, use an example program, check that it works)
- Start over (remove the sensor), only use the L293D motor driver shield (with a motor), use an example program, check that it works)
- Now combine both circuits and programs or if you feel confident enough, start making your entirely new program.
