Hello All,
I'm building a new computer for our Pinewood Derby Track. The
directions show +positive and -Negative for the LED's. The High-Output
Infrared LED's show Cathode. The Infrared Phototransistors show
Collector and Emitter.
Is the Cathode the + or - side?
Is the Collector the + or - side?
Help if you know the answer
