Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

The project requires an Arduino Uno, an L293D motor driver, IR sensor modules, a battery, BO motors, and a hobby robot chassis. The circuit integrates sensors, motor driver, motors, and Arduino, with ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. In this project bot follow the ...

To work with the sensor we need to power the sensor first, for that we are using the 5V and GND pin of the Arduino UNO Board. As shown in the above arduino soil moisture sensor circuit diagram we have ...

Fig. 1: Block diagram of the smart slide pointer Fig. 2: Author’s prototype Circuit and working. The circuit diagram of the smart slide pointer is shown in Fig. 3. It is built around Arduino Leonardo ...

This infrared sensor based self-adaptive system measures the density of vehicles using infrared sensors at each of the four roads at the intersection. It sends data to Arduino Mega microcontroller ...
