A very simple IR remote control switch for an electrical appliance

This project describes a technique of adding the remote control feature to an electrical appliance. The goal is to construct a black box where you can plug-in your 120V AC appliance (it can be easily modified for 220 V mains supply too) and control the ON and OFF operations with a TV or DVD remote that uses modulated infra-red (IR) pulse train of 38 KHz frequency. I did this project for my wife who studies late at night on her bed and later feels tired to stand up and turns the light off. Now she does it from bed with the TV remote. The good thing about this project is that it does not use any microcontroller and is only based on the CD4017 decade counter IC.

Circuit diagram

The original circuit diagram for this project was published in the May 2005 issue of theElectronics For You magazine. The circuit diagram below is mostly the same. It uses a TSOP1738 IR receiver module at the input side to receive the 38 KHz frequency IR pulses from the remote control. Under normal condition, the output pin of the IR module is at logic High, which means the transistor T1 (BC557 PNP) is cut-off and its collector terminal is at logic Low. The collector of T1 drives the clock line of the CD4017 decade counter.
Now lets see what happens when somebody faces a TV or DVD remote towards the TSOP1738 and presses any key on it. The TSOP 1738 module receives the train of 38 KHz IR pulses from the remote, that makes its output to oscillate too. These pulses are inverted at the collector of T1, which finally go to the clock input of the decade counter. The arriving pulses could increment the CD4017 counter at the same rate (38 KHz), but because of the presence of the RC filter circuit (R1 = 100K, C1 = 10 uF) between the collector and the ground, the train of pulses appear as a single pulse to the counter. Thus, on each key pressing, the CD4017 counter advances only by a single count. When the user releases the key, the C1 capacitor discharges through the R1 resistor, and the clock line is back to zero. So every time the user presses and releases a key on the remote, the CD4017 counter receives a single pulse at its clock input.
