DIY Radio Control Electronic Projects
This project, called “Simple-Timer” is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.
The “Simple-Timer” includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).
