Make a Chart of the Signal Strength

Use code to detect the signal strength between two micro:bits and plot the result on a bar chart.

Step 1

Challenge: Create a program that shows the current signal strength between two micro:bits on a bar chart. The bar chart should change as the signal strength changes.

Speak with a partner about what you need to do to code this app. 

Look through the palette. Which blocks might be most useful?

Step 2

Test your solution on the simulator.

Download your code onto the micro:bit and test it.

Tip: There's no right way to complete this challenge, but here’s one way you might do it. The weaker the signal, the more lights are turned on.
