IR Remote Control

Description

This Project is based on TSOP IR receiver; IC 555; IC 7474; BC 187.Here we have made use of TSOP 1738, an IR receiver which detects the IR rays from the remote. IC NE555 is the next important part which produces a clock pulse for toggling the D flip flop.The relay helps to connect any electrical devices to the circuit and you can control any electrical equipment, like light and fan. You must need regulated power supply of 5 volt to do this circuit because TSOP requires 5v. Its voltage should not exceed 5V.

Components

1 × IC7474 wo D-Type Flip-Flops in a 14-Pin DIP Package arrowOutputs Directly Interface to CMOS, NMOS and TTL

1 × IC NE-555 The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications.

1 × IC 7805 7805 is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. ... The voltage regulator IC maintains the output voltage at a constant value.

1 × IR TSOP 1738 TSOP17XX is a commonly used IR receiver for Infrared PCM remote control systems. ... This component is built with PIN Diode, Preamplifier and internal filter for PCM (Pulse Code Modulation) frequency and its epoxy package is designed as an IR filter.

1 × BC187 DiscreBC187(Data Sheet) is a General purpose switching and amplification,e.g. driver and output stages of audio amplifiers,it consume Low current (max. 100 mA) and Low voltage te Semiconductors / Transistors, MOSFETs, FETs, IGBTs
