Light sensor and the rows and coloum

I created a project using a Micro:bit, a light sensor, and Tinkercad.

My project is all about how the Micro:bit LEDs can light up using rows and columns depending on the light level. When I click the “Start Simulation” button, I can increase or decrease the light sensor value. As I increase the light level, the LEDs on the Micro:bit begin to turn on, one row or one column at a time. When I make the light level lower, the LEDs slowly disappear again. I think this looks very cool because it almost feels like the Micro:bit is breathing with light.

To build this project, I used components like the Micro:bit for the LEDs, a light sensor to control the brightness, and the code editor in Tinkercad. The code is the most important part. I used the “while true” block to keep the program running forever, so I don’t have to keep repeating the instructions. I also used “input light level” to check how bright the light is. With “LED plot,” I told the Micro:bit exactly which LED should turn on at which light level. I added a one-second pause and then used “clear screen” to reset the LEDs before the next cycle.

This project can be used for signaling someone or even as a fun party light because it keeps blinking and changing patterns. I really enjoyed making it, and I learned how rows, columns, and light sensors work together.
