Electronic target circuit (exported to Europe, America and other places)

In order to thank many brothers for their support, I now post the circuit diagram of the electronic target that I have made before and is currently in production (mainly exported to Europe and the United States) for the reference and correction of interested brothers. Since it is still in production, the code and the target disk are not available, so please forgive me. The target has five game rules, can be played by 1-4 people at the same time, and has music and lantern effects. (Editor: shizhou)
