The author had 2 remote controllers to control 6 outlets in his apartment. He wanted to remove the remote controllers and control the light with his i-phone. Just by using Arduino & Ethernet shield, he made his own controller.
The parts that are needed
- 1x Arduino uno (can be any arduino)
- 1x Ethernet shield (it should be the one with the w5100 chip)
- 1x mixro sd card
- 1x 5v to 12v stepup
- 1x 433mhz transmitter
- 1x 3d printed box (stl provided)
- some 433 mhz controllable wall outlets
He made the external case using 3D printer.
