Infrared Transmitter and Receiver : 6 Steps - Instructables

Using the switching output of the 555 timer to drive an infrared (IR) LED; meaning the LED will turn off at about 38,000 times per second. This is done so that the receiver will detect the signal using a IR receiver sensor that is tuned to detect that frequency and turn the red LED on. You might be asking yourself how this works. The answer is fairly simple, this will be similar to how your ...

555 Timer : 8 Steps (with Pictures) - Instructables

Operation: Fig 5 shows the output from the 555 timer. You can see that the duration of the high pulse is about , as expected. Also notice how a new pulse is triggered every 10 ms, each time the signal from the Arduino drops low. Fig 6 shows the output from the 555 in blue and the output from Arduino digital pin 0 in yellow. You can see that the Arduino signal is normally high, it drops low for a tiny fraction of a second, only visible when we zoom in the time…

IR Transmitter and Receiver 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 TSOP. So we are using 555 timer in Astable mode to oscillate the IR at 38KHz frequency. As we know oscillation frequency of 555 timer is decided by resistor R1, R2 and capacitor C1.
