My first Awesome IKEA lamp had multiple trimmers and push buttons to setup speed, brightness and color. I now added a remote control to get rid of all these. I chose one of these common rgb remote controls that are shipped with every other cheap rgb lamp. I got it from dx.com. The led i use is a 3W rgb star led from ebay with the following specifications:
Red=2,4V, Green=3,4V, Blue=3,4V, 350mA per channel
Make sure you do not get one with common “+”; if so you can’t use p mosfets but must use the n version instead. Common ground is no problem. You’ll get a complete partlist from the eagle file. The main changes from the original layout are:
- P_MOSFET: IRLML6402
- IR-RECEIVER: TSOP 31238
- IR_REMOTE: CR2025
I uploaded everything including the schematic, board and the code: Download!
The code is neither commented nor nice. Feel free to improve it 😉 There is a little problem with this version; the p-mosfets seem to have great leakage current so the leds wont turn off completely. I think the PORTD has to little output power…
