Step 3: Create a program to display water temperature data as an LED bar graph
Step 3: Create a program to display water temperature data as an LED bar graph
First, plug the water temperature sensor into your grove shield at pin 0 and plug your LED lights into the grove shield at pin 1.
First, plug the water temperature sensor into your grove shield at pin 0 and plug your LED lights into the grove shield at pin 1.
Then, click here to open a Makecode program that displays water temperature data as an LED bar graph. Read the code comments to understand how the program works and then download the program to your micro:bit.
(To find the DS Temp Extension, in the search bar for extension, copy and paste this link "https://github.com/bsiever/microbit-dstemp-alpha". Then you can add the extension "DS Temp".)

Test the program! Hold the water temperature sensor in your hand, hold it near your grow lights, place it in a cup of ice water. How does the bar graph change?
