An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

In this project we are introducing a simple IR receiver circuit and code that will allow you to integrate remote control function to various projects using the ATtiny85 microcontroller. Following is ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Saving the IR Remote Decoder Data into Excel Sheet Now to send data to an Excel sheet, we are going to use PLX-DAQ. It is an Excel Plug-in software that helps you to write values from Arduino to ...

Connections are simple. Connect GND pin of the sensor to GND pin, Vcc pin to 5V pin, and O/P pin to digital pin 2 of Arduino Leonardo, respectively, as shown in Fig. 3. Fig. 3: Circuit diagram of the ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Circuit Setup: Wire the LED matrix to the Arduino Nano as described in the circuit setup section. Arrange the LED matrix to display patterns or messages. Code Upload: Connect the Arduino Nano to your ...

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 ...

Once he received the boards, alll of his prototyping components were swapped out with SMD versions, including a TQFP ATMega168 chip in place of the full-sized Arduino board.

The beacon is just a simple ATtiny13 that flashes a message with an invisible IR LED. To receive the messages, [Kurt] made a scavenger decoder shield for an Arduino.
