Grandfather Floor Clock Interior Lighting – Breadboard

The first step was to test the LED strip control circuit.  I’m using a TIP120 here; they are not as efficient as a MOSFET but they have sufficient current capacity for this application and were already at hand.  The resistors are both 1k ohm 1/4 watt.clk-led-control-p1_bb Continue reading Grandfather Floor Clock Interior Lighting – Breadboard

  • Must have manual on/off switch
  • Only active if there are people present
  • Light source not visible when the light is off

I chose an Arduino Uno as the controller.  I have a few of them around and have wanted to find an appropriate project to give them a try. Continue reading Grandfather Floor Clock Interior Lighting – Design Choices
