Design And Construction Of A PC-Based Candle Igniter

ABSTRACT

This work is on a PC based candle igniter system that lets you light up a candle using matchsticks by just pressing the ‘Enter’ key on the PC’s keyboard. It is especially useful when celebrating such occasions as birthdays and anniversaries.

The number of matchsticks required to light up the candle is placed on the candle. The heating coil for igniting the matchsticks is kept near them.

The interface circuitry between the PC and the heating coil for the candle-matchsticks arrangement comprises an inverter, monostable and relay driver. Transistor BC548 (T1) acts as the inverter, IC 555 (IC1) is configured as the monostable circuit and transistor SL100 (T2) is the relay driver.
