Crocodile clips
The large holes at the bottom of the board are designed to attach alligator/crocodile clips to create electrical circuit with other components.
~hint
No crocodile clips!?!?! Use wires or aluminium foil!
~
Connecting crocodile clips
The hole for P0 and GND allow to grab the board on the side which makes for a great grip.
Pass one jaw in the hole and grab the side of the board with the other jaw.
For the center holes, P1 and P2, you can also grab the bottom of the board but they are a bit harder to grip.
You can also grip the board between the jaws. In which case, you will want to make sure to avoid overlapping the jaws with the other pins as it will create short-circuit in the board.
Adding a little tape helps keeping the crocodile clips in place.
Example: on pin pressed with random numbers
This example displays a random number every time the crocodile clip holds GND then connects and disconnects the P0 pin.
Each time the crocodile clip is firmly connected and disconnected from pin P0,
the @boardname@ will return a random Number between 0 and the parameter limit.
input.onPinTouchEvent(TouchPin.P0, ButtonEvent.Down, () => {
basic.showNumber(randint(0, 10))
