The legs of the LEDs are twisted, to show that I have the anodes going to the same row as the resistors.
Right now, this is all that is needed. Just a few indicator lights, and a button to simulate picking up the handset to start the program (that tells the joke.)
Eventually, I will wire the LEDs to a more permanent place in the phone.
Currently I am using parts from a Raspberry Pi 3 and a Elegoo Upgraded Electronics Fun Kit.
