Resolver simulator. This converts a 0-10V input signal to a differential sine/cosine signal to simulate a resolver for a motor drive. We built an Arduino “shield” mezzanine board with analog electronics and a multiplying DAC to take the motor drive reference signal and the input voltage to create the resolver signal.

This is what the output looks like.

Tilt, G-force and light sensor. If the angle, acceleration value or light intensity exceeds a predetermined threshold, a servo motor is activated to move a load. It’s shown here mounted onto a Spin Indexer so the Tilt function can be tested.
