Karthik, a young science enthusiast who loved soccer, wanted to solve a real-world problem he imagined. He thought about "Biryani Boy," who loved blasting music in his car while eating, but struggled to get the ambient lighting just right—the light was either too bright or too dim, ruining his vibe.
Inspired, Karthik designed the "Light Bit," a smart ambient light system that adjusts the brightness of red, green, and blue LEDs to find the perfect balance. Using a micro:bit as the brain, he connected the LEDs to its pins and programmed buttons to control each color’s brightness—button A for red, button B for green, and both buttons together for blue.
Karthik cleverly used variables to track the brightness levels and included code to ensure these levels didn’t go beyond safe limits. He added a buzzer that alerted the user if the light was too bright or too dim, helping Biryani Boy keep his lighting perfect without constant fiddling.
The project’s code used functions to handle button presses and brightness adjustments, keeping the system efficient and easy to use. A continuous loop updated the LED brightness and monitored the combined light intensity, triggering the buzzer when needed.
During his presentation, Karthik demonstrated the light bit in action. Pressing buttons smoothly changed the LED colors, and the buzzer softly warned when brightness was out of range. This simple yet effective system showed how technology could improve comfort and experience, turning ambient lighting into an interactive, personalized feature.
Karthik’s Light Bit was more than a gadget—it was a thoughtful invention blending coding, electronics, and user-centered design to make everyday moments brighter and more enjoyable.
