Mustang Indicator Design

 

For my Go Cart, i wanted to add Turn signal indicators. I liked the shift register design of the mustang indicator lights, so I based my design off that.

One specific requirement: The satisfying “Click” needs to be audible. For this reason I used relays instead of directly driving LEDS.

A bit overkill, but the AT45 does exactly what i need for this project

Of course, we need a way to program the AT45
