Create circuits
We could teach our kids about electrical current by giving them a plug and an outlet, but that seems dangerous. Instead, we'll use Scratch, a PicoBoard, and an alligator clip to demonstrate electrical resistance.
Time for action – complete the circuit
Once again, we will find a sprite that has some scripts attached to it and modify the control to work with the alligator clips on the PicoBoard:
Start a new Scratch project and select choose new sprite from file.
Delete the original sprite.
Open the Fantasy folder and select the Jumping Jack sprite.
Replace the key up arrow pressed? block with the sensor block and select the A connected option.
Replace the key right arrow pressed? block with the sensor block and select the B connected option.
Replace the key left arrow pressed? block with the sensor block and select the C connected option.
The PicoBoard has four connectors labeled A, B, C, and D. Plug a set of alligator clips into each of the A, B, and C sensors.
