Wireless Doorbell Alert

Context: In a big house (or school), it’s useful to have a wireless doorbell – press a button at the door, and a bell rings elsewhere. Let’s create a simple wireless alert system to understand communication between devices.

Task: Use two Junkbot Core devices (or one device with radio features and another acting as a receiver). Program one as the transmitter: when its button is pressed, it sends a wireless message ( in MakeCode or similar). Program the second as the receiver: it constantly listens for the message. When received, it activates a buzzer or plays a tone and maybe flashes an LED to simulate a doorbell ringing inside. Ensure both devices are set to the same radio group/channel.

Expected Output: A two-part doorbell system that works through the air. During a demo, you place one device at the “front door.” When you press its button, the second device (placed across the room as the “chime”) immediately rings or beeps and lights up. This mission shows how wireless tech (like IoT gadgets) can be used for practical home systems and introduces communication between micro-controllers in a straightforward way.
