Step 12: An Alternate Hardware-Based Approach to Commutation Logic
It has occurred to me that the operations performed by the Arduino in this project are so simple that it almost seems like a waste to use a microproce...
Step 6: Hall Sensor Circuits
Now that you have the Hall sensors properly mounted on the motor, connect each of them with the circuit shown below and test them out with a DMM or oscilloscope to ensure that the output goes high and low as the motor is rotated. I run these sensors at 5V, using the 5V output of the Arduino.
