Today, I’m going to create a simple infrared (IR) sensor circuit that’s great for beginners looking to understand remote control concepts. Let’s break it down step by step.

First, grab a mini breadboard. This will serve as the base for assembling our components. The next component you’ll need is an LED. Insert the LED into the breadboard, ensuring that the longer leg (the positive) is facing one side, and the shorter leg (the negative) is facing the opposite side. This will determine how the current flows through the circuit.

Now, take a 100Ω resistor. Insert it into the breadboard, connecting one of its pins to the negative pin of the LED. This resistor limits the current flowing through the LED, preventing it from burning out when powered.

Next, we need an IR receiver. This component detects infrared light, similar to how TV remote sensors work. Insert the IR receiver into the breadboard. Connect its longer leg (which is usually the signal pin) to the pin of the resistor that’s already connected to the LED. The shorter leg of the IR receiver will be used for the ground connection of the battery, so leave it unconnected for now.

With the core circuit set up, we’re almost done. Now, grab a 9V battery. Connect the battery’s negative terminal to the short leg of the IR receiver (ground). Then, connect the positive terminal of the battery to the positive pin of the LED. This provides power to the entire circuit and sets it up for testing.

Next, we need a simple IR transmitter to complete the test. I’m using an IR LED, commonly found in remote controls. For power, I’ll use a small coin cell battery. Insert the coin battery between the two pins of the IR LED (one pin touching the positive side and the other pin touching the negative side of the battery). This makes a quick and easy DIY remote control for our project.

Now it’s time to test the circuit! Bring the powered IR transmitter near the IR receiver on the breadboard. As you approach, you’ll see the LED light up, indicating that the IR signal has been detected and the circuit is complete. This demonstrates how infrared light can control electronic devices from a distance.

For more fun and practical use, you can experiment with using different IR transmitters, adjusting the resistor value, or adding more LEDs to create a stronger signal response. It’s a fantastic beginner project to introduce the concepts of IR communication and sensor-based electronics.
