  1. WORKING Christmas Tree Project Circuit

    why are the numbers on the integrated circuit different from the ones on the outside of the integrated circuit. this can be confusing when wiring, i am assuming the numbers on the outside of the circuit are the pin numbers. Hypermung designed the circuit and was hoping he could shed some light on this. thanks Richard
