BASIC REMOTE TESTER
Description: This circuit is used for testing your TV, DVD, VCD, etc.
remote control. This is the principal module for making infrared based protest counter.
According to the datasheet of TSOP4838, the input voltage to IR sensor
should be 3V-5V. When the sensor gets infrared signal, the voltage at its VO
pin drops and that triggers the BC557 transistor. At each trigger signal, BC557
glows the LED. Thus, you can see the response of your remote control signal.
In the schematic below, for TSOP 4838, V1 is INPUT and VO is OUTPUT.
FRITZING application does not have TSOP4838, so, I used the available infrared module. The available module does not look like the one we use in this experiment.
In real, the experiment set up looks like this:
It is not checked
