Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
A ~$30 bench rig — an Arduino Uno R3 plus two MCP4725 DACs — that answers one question about a MOSFET: is it viable for cascaded digital logic? It sweeps gate and drain voltages and reports gate ...
