The OUT Pin of IR Sensor Module 1 is connected with the Analog Pin A0 of the Arduino Uno.

The VCC Pin of IR Sensor Module 1 is connected with the 5V Pin of Arduino Uno.

The GND Pin of the IR Sensor Module 1 is being attached to the GND Pin of Arduino Uno.

NOW, You are Ready to make a Line follower Robot Car

Then when we connect, open up the Serial port screen which transmits at 9600 bits per sec and checks the message, as per written in the program.Īs per the program, the LED also blinks and illuminates based on the Obstacle sensor output. For better and precise testing, we can solder the wires (jumper wires) to the sensors as their connected pins are not portable. Once Upload is done the TX RX LEDs blink quick.

Once connected to suppose COM3 port, open the Arduino Set up IDE where the code set up is done, compile the code once and then Upload the code to the Board. Now, time to connect the Board to the Computer using the USB jack.

When the full circuit is done and the code set is also done. You Can adjust the sensitivity by rotating inbuilt potentiometer on above the IR Sensor.ĬLICK TO SEE THE CODE TO CHECK RANGE FOR IR SENSOR NOTE - Before Making the circuit must check the IR Sensor Module range. It consists of two H-Bridge circuit inside the IC which can rotate two dc motor independently. Input Pin2 ( To rotate the motor in Anti-clockwise direction. Input Pin1 ( To rotate the motor in Clock-wise direction. It is Recommended Power Supply(36V is Maximum) The infrared receiver that receives the signal transmitted by Infrared Emitter Illuminates when the obstacle is detected Output Pin that goes low when Obstacle is in range

Ground (It grounds the Input and completes the circuit path)

On board Obstacle Detection LED indicator.

Active output level: Outputs Low logic level when obstacle is detected.

Detection range: 2cm – 30cm (Adjustable using potentiometer).

The sensor has very good and stable response even in ambient light or in complete darkness. The module has on board potentiometer that lets user adjust detection range. This particular Sensor Module has built in IR transmitter and IR receiver that sends out IR energy and looks for reflected IR energy to detect presence of any obstacle in front of the sensor module.

Highest Output Current 1.2 A Per Channel.

This particular Motor Driver Module is a quadruple high-current half-H drivers.
