Circuit diagrams of electronic hobby circuits
These are some circuits of infrared based remote controls and alarms which consists of an IR transmitter and an IR receiver which are built around IR LED and IR sensor modules and some associated components.

In this shooting game one can improve their accuracy and speed very simply.We have to point the gun towards the target and press the switch.IR rays from the gun strikes on the target IR sensor module and a confirmation LED just lits and an audio indication is also heard along with it.This circuits use only a few components which are easily available in local market.
