Quick Crossing Flasher Update

Electronics, Trains

I took a little time this evening to revive a project I’d started quite a while ago but hadn’t gotten much attention for quite a while. Some time ago I decided to create a crossing controller powered by an Arduino. I had gotten as far as a working prototype of the flasher on a breadboard. Tonight I decided to try transferring that two some simple PC board to keep it tidy. I found some small square boards pre-drilled at radio shack that I decided to give a whirl along with some connectors. The idea being that this component could be easily disconnected from the Arduino and lights as needed. Generally I wanted to be able to remove the gates from the module for transportation.

On the bottom are all the inputs as I’ve labeled them, I’ve started putting the components on for light #2. The blue resistors are what came with the lights, the brown one is for the transistor, and the transistor itself controls the lights being on or off.

For L2 I need to connect the input to the resistor where I’ve marked and ground to the transistor where I’ve marked GND. I need to repeat the arrangement for L1 and run a connection to the 5V output.
