Arduino Uno : Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ...

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 ...

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 ...

In this tutorial, we are going to interface E18-D80NK IR Proximity Sensor with Arduino. The E18-D80NK is an advanced low-cost IR Proximity Sensor with an obstacle detection range of 3 cm to 80 cm. The ...

The Circuit diagram for IR Remote Decoder using Arduino is given below: The connections are very simple as the IR Receiver sensor only has three pins, Vs, GND, and Data. Connect Vs and GND pin of IR ...

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, makin… ...

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 ...
