Arduino Uno PWM to I example shield with project in Protel Format and LTSpice

Here is a Arduino Shield as a Protel project with a PWM to voltage to current circuit.

It can be used to source a programable current or sink a programable current.

The circuit is included as an LTSpice circuit also.

This actually started as a base Protel project for making shields but I had to put an example circuit.
