Basic remote tester

Description: This circuit can be used for testing your TV, DVD, VCD, etc. remote control. This is the fundamental module for making infrared based object counter. This project has been derived from “Remote tester project” .

DATASHEET OF TSOP4838

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.

IR1
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:
