An isolated analog output for Arduino Uno
Giovanni Carrera discuss how to achieve an isolated analog output on Arduino. He writes: This project completes the series of my articles about the Arduino analog I/O with the aim to use it as a controller of small automation systems. In control systems of the industrial plants it...
