Live Missions
Rain Monitor Alarm
Use a rain sensor (or you can improvise with a moisture sensor or even two wires that get connected by water) placed where it would get hit by rain. Connect it to the Junkbot Core and add a buzzer or...
Wireless SOS Button
Similar to the wireless doorbell, use one microcontroller as a transmitter with a clearly marked SOS push-button, and another as a receiver with an alarm. Program the transmitter to send a radio mess...
Parking Distance Assistant
Use an ultrasonic sensor to measure distance in front of a model car or device. Program the controller to produce different beep patterns depending on distance. For example, if the object is far away...
Smart Irrigation System
Set up a soil moisture sensor in a potted plant’s soil and connect it to your controller, along with a small water pump or a servo that opens a valve (you can simulate with an LED if no pump is avail...
Voice-Controlled Light Assistant
Utilize a microphone and a laptop (or external AI service) for speech recognition since the microcontroller alone can’t decode voice. Train or program it to recognize two phrases: one for turning the...
Fitness Tracker Wristband
Using the Junkbot Core’s accelerometer (motion sensor), program it to detect a step – you can interpret a sudden jolt in the vertical axis as a step while walking. The device should count these steps...
Smart Washroom Fan
Use an ultrasonic sensor or PIR sensor placed at the door to detect if a person enters. If motion is detected (or the door opens), assume the washroom is occupied – trigger a fan (you can simulate wi...
Intruder Alert Alarm
Set up a PIR motion sensor facing the area you want to protect. Connect it to the Junkbot Core and add an output like a buzzer or loud piezo speaker. Program the system so that when motion is detecte...
Wireless Doorbell Alert
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 MakeCo...
