Hi I am fairly new to ATTiny85 and wanted to know if I can drive 2 hobby DC motors and use 2 LDR to control each side of the motor. The led is just for indicating if the circuit is working. Please see the attached circuit diagram. I am still taking baby steps so if you have a circuit with just 1 motor and LDR please share. I plan to Either run all of this via a 9V power supply or a 2 pack AAA battery source.
If I plan to run them on cr2032 will it drastically change as i want to make them as small as possible.
