Target shooting games are often popular at fairs. Today, we will create a game using micro:bit that can be played at home.
Materials
One Micro:bit board
One power module providing 5V and 3.3V output
One MG90S servo motor
One photoresistor
Several DuPont wires
One 18650 battery holder
Two 18650 batteries
One laser pen
One iron wire
One circular cardboard
Wiring Instructions
Connect the photoresistor to P1
Connect the servo motor to P0
Program Instructions:
The programming part is quite simple, as shown below
Testing
If the servo motor is powered by 3V, the response will be very slow and sometimes it may even stop working. Therefore, choose to use 5V power.
Install the power module providing 5V and 3.3V output
Use 3.3V for the micro:bit, and 5V for the servo motor. The wiring is shown in the diagram below
When the installation is complete, it looks like this
Start the game
