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.
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:
