I am just looking for some general direction for which type of motors, and basic wiring advice.
I used an Arduino with a small Pololu Dual Brushed Motor Driver and 2 small brushed motors. I also hooked the Arduino up to an accelerometer. I had the a single 5v battery for the whole system. The 3.3 V was used for logic and the 5V was used for the Arduino and to drive the motors.
Everything worked, however I noticed a lot of noise introduced into the accelerometer signal after the motors where connected and turned on.
And am designing an entirely new model and design. I want to start from scratch and design the circuit so that I can reduce noise in the sensors so i can have a fine precision control. I think what I need is a brushless motor and external ESC ( electronic speed control ) which should be powered from their own battery. Then I should use a different (smaller) battery for the arduino and sensors. Hopefully there won’t be a way for noise form the motors to affect the accelerometer reading.
Is this the right direction to go with hardware?
