Ir Remote Control Circuit Diagram. Ir beam from remote control travels very short distance with narrow angle so that here we given ir remote control extender circuit with few components. Cd4017 with base and tsop 1738 ir receiver resistors.
Circuit diagram construction and working the ir receiver tsop 1736 is used to detect the ir beam from remote control output form this sensor is fed to not gate and inverted output is connected to transistor q1 base this npn transistor acts as. In above ir remote control light switch output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017. 4 7k x 2 1k 100 ohms 100k.
Cd4017 with base and tsop 1738 ir receiver resistors.
In above ir remote control light switch output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017. This current is given to the inverting input of 3130 ic which will get triggered by this current and give amplified output. A transmitter section and the other receiver section. In above ir remote control light switch output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017.
