Digital Reads and Writes

Here's an example wiring that goes with the code below.

We have two switch buttons, connected to signals #1

and #2, the other side of the buttons connect to ground

There's also two LEDs, connected to the signals #3 and

#4 and the negative wires connected to ground. (All the

3.3V and Ground pins are connected together so you

don't

have

to use the ones right next to the signal pin!)

Note the pull up resistors for the buttons. Seesaw does

not allow enabling internal pullup or pulldown resistors

at present. Also 330 ohm current limit resistors are

shown for the LEDs.

Here is the MakeCode that reads the buttons on signal #1 and #2 and lights signal #3 and signal #4 if the

corresponding button is pressed:
