Light sensor driven device powered with Microbit

Through programming in Microbit, we created a Rube Goldberg device to pop a balloon. A light sensor is first covered with a piece of cloth. When a heavy object drops from the tube and falls into the bucket, which is tied with the cloth, the cloth would be raised and the light sensor would detect light. Afterwards, the servo motor is programmed to rotate and the needle attached to it pops the balloon.
