I am building a Haynes Roadster car and want to be able to do sequences with the rear LED lights when at shows etc. I am happy programming an arduino, however, i’m no electronics expert. I am needing some advice on where to buy a reliable PSU to power an arduino from noisy car electrics. As I need a level of integrity, is there any arduino that is more robust than others?. I will be switching LED lights with relatively low current <500mA - would rather switched with transistors rather than relays as would like a strobe effect and don’t think relays will switch quick enough. Again any advice on a off the shelf module (10 output) that could achieve this?
(ill be building in a bypass so lights will function as normal on the road)
Any advice much appreciated.
