Read a push button on a digital pin and draw its value on the dashboard chart.

This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on.

The steps

  1. We add a While loop, which repeats forever.
  2. We create a number variable called reading.
  3. We declare a digital input called button on pin 2.
  4. Inside the loop we set reading to what the button gives us.
  5. On the dashboard we draw a chart and give it the variable reading.

When you finish, the app takes you straight to the next tutorial in the path.
