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.

- Must have manual on/off switch

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
