Task @showdialog

Write a program for a thermometer that outputs a heat-free signal when a temperature of 30°C is exceeded.🍦

• If the measured temperature > 30°C, display an ice symbol on the LED matrix and switch the RGB LED to ‘red’.
• If the measured temperature is < 20°C, switch the LED matrix off and the RGB LED to blue.
• In all other cases, switch half of the LED matrix on and the RGB LED to green.

Create query

Select a ||logic.if then else|| query from the logic blocks and insert it into the ||basic.forever|| loop. Click on the + of the query to add another condition.

Create conditions (warm)

Replace the first “true” block in the query with a ||logic.compare (=)|| block to compare the measured ||input.temperature| with the highest threshold value. Change the operator to >.

Create conditions (cold)

Replace the second “true” block in the query with a ||logic.compare (=)|| block to compare the measured ||input.temperature| with the lowest threshold value. Change the operator to <.

Define output

Complete your program by adding the output via the LED matrix and the RGB LED for the different cases. Use the blocks ||basic.show leds|| and ||basic.set LED to||.

Done! 👍
