This lesson gets temperature sensor data from the built-in sensor. The lesson uses two Micro:bits. One collects temperature data and the other receives the data. The data is collected and saved to a comma-separated value file.The code uses the Micro:bit’s radio to transmit the data. Use this to discuss how radio technology works. Radio technology uses frequencies. Frequencies are measured in amplitude and modulation. Discuss how amplitude and modulation are used to send information like music an
