4-20 mA current output for Arduino Uno

Giovanni Carrera writes: The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller ATmega328 and numerous other chips, such as the PIC. One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino.” 4-20 mA current output for Arduino Uno - [Link]
