12V Lighting Controller
Description:
A 4-channel controller for anything that needs +12V switched at up to
3A per channel. Uses the "RBBB" arduino design for control, and an
LMD18400 4-channel high-side automotive switch from TI. All 4 channels
are PWM and the there are 2 interrupt and 2 analog/digital inputs with
protection circuitry. Use this for "common cathode" LED strips or other
loads where +12V needs to be switched on the high side.
Two of the inputs are interrupt-driven and 2 have analog capability, so this could be used as a 1-door sub-controller for home automation using a port of the "Open Access Control" or as a converter/interface to another system.
