In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by D9 of the Arduino Uno (TP1) while its cathode (K) to a ~1kHz signal available at D8 of ...

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 ...

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 ...

There is only one common solution for this problem: Modulate your IR signal so that your sensor can detect an IR variation rather than a fixed IR level. In this tutorial, we are going to interface E18 ...

With strong reflectance, the output voltage tends towards GND; with weak reflectance, it tends towards Vcc. The resistor wired in series with the infrared LED sets the operating current to a safe ...

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 ...

For decoding, use any TV/DVD IR remote controller. The circuit diagram for the decoding circuit is shown in Fig. 2. It is built around Arduino Uno board (Board1) along with IR sensor TSOP 1738 wired ...

So this inspired us to use GSM module for this project since the telecom network is widely spread within rural & urban area of the India. This system is used to monitor physical parameter like heart ...
