From the project

Wifi module to control Torrent LED Light Bar

The purpose of this project is to create a system for the user to be able to control the light bar wirelessly, using his smartphone.

According to the manual the bar is controlled by 15 wires. The voltage at these wires should either be 0 or 12V, respectively low and high level. Some wires should be hold at high level continuously of activating functions, more advanced ones requires mode selection by tapping several times on the wire (sending 12V pulses).
