In this post, we will make a simple IR remote tester. Since infra red rays are invisible to light we can't check it using naked eyes. Therefore, we need some device/ instrument for testing it.
One simple method to check IR remote is by using mobile or digital camera. However, it's not handy.
We will make a simple circuit using TSOP1838
We simply need a Tsop1838, one led (RED 5mm) and a 220 ohm resistor.
We have to connect cathode of led to output of tsop sensor and anode to +5 volt. A series resistor of 220 ohm or 330 ohm should be connected in between anode of led and +5 volt in order to limit the current.

Once the circuit is made, provide voltage supply to the circuit.
