In the schematic, you can also find an LM358 Op-Amp which is doing all the comparison work and generating the output. Other than that, there is a potentiometer that can be used to adjust the ...

If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown ...

At the heart of the circuit lies the CD4027 IC, which is a dual JK flip-flop. JK flip-flops are bistable multivibrators capable of storing one bit of data and toggling their state with every pulse ...

Schematic of IR Beam Breaker Circuit. TSOP1738 IR sensor module responds to only 38 kHz pulsed infrared rays. It will not sense continuous IR ray from the IR LED. So a transmitter circuit(as one in TV ...

IR Transmitter Circuit Diagram. We are using TSOP1738 as IR receiver, so we need to generate the modulated IR of 38 kHz. You can use any TSOP, but you need to generate IR of respective frequency as ...

Tired of loud TV ads? In 2012, Peter de Bruijn built the Mini-Mute — a clever circuit that let him mute his TV with a simple ...
