The Arduino Uno IR Sensor detects infrared (IR) radiation emitted by objects. It typically includes an IR transmitter and receiver pair, with the receiver detecting reflected IR light. This enables ...

All modules are well-known off-the-shelf parts so we won’t go into details this time. Getting started with the Maker Uno RP2040 board using the Arduino IDE As mentioned in the introduction, the Maker ...

Connect the VCC and GND pins of the IR sensor to the 5V and GND pins of the Arduino, respectively. Connect the OUT pin of the IR sensor to D2 on the Arduino. Connect the anode (+) of the LED to a ...

6. Line Following Robot The line follower robot is a very interesting, easy to make autonomous robot. As the name suggests the line follower robot will follow the line drawn on any surface. To build ...

Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...
