Step 3: Show all of your garden information on your OLED screen
Step 3: Show all of your garden information on your OLED screen
Use what you have learned from programming the micro:bit from the previous Episodes to create a program to show all your data on the OLED screen and change the LEDs color if the data is too high or low.

If you need a little help, check out this code which combines what we have learned in the previous episodes to collect temperature and humidity data, show it on the OLED screen, and change the color of the LEDs!

Try adding other types of data to this program. Note: check out how the LEDs are broken into two sections in this code, one part for humidity and one part for temperature.

Step 4: Start a journal for your plants
Step 4: Start a journal for your plants
Start a journal to keep track of how your garden is growing. You can create a digital journal or print the pages out. Keeping track of how your garden is growing is a good way to learn more about what your garden needs to be healthy.
