Connect pin A1

A2 to ground, using a wire or alligator clip, then disconnect it to send the key press "A" or the string

"Hello world!"

This wiring example shows A1 and A2 connected to

ground.

Remember, on Trinket, A1 and A2 are labeled 2 and 0!

On other boards, you will have A1 and A2 labeled as

expected.
