To make the ELapShelf even more useful, I've decided to add some accessories.
The first will be a touch activated reading lamp.
The lamp will be powered from 5VDC and be controlled using a NXP PCF8883 Capacitive touch proximity switch IC that was included in the Make Life Accessible kit.
The basic circuit (taken from the NXP PCF8883 data sheet) is as follows:
I used a SparkFun SOIC to DIP 8 pin adapter PCB along with a few Rs and Cs to wire up the touch control.
I don't need to run the switch through the FRDM-KV31 board, but that might change later.
Here's a short video of the switch circuit in action.
