Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...
The I2CKeyPad8x8 library implements the reading of a 8x8 keypad by means of a PCF8575. Smaller keypads, meaning less columns or rows (e.g. 5x4) can be read with it too. Sometimes you need to control ...
The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...
The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...
This project demonstrates the interfacing of an Infrared (IR) sensor with the Arduino UNO R4 WiFi to detect obstacles in real-time. It utilizes digital signal processing to monitor the environment and ...
Abstract: This paper studies the link-layer error-control solutions for low Earth orbit (LEO) satellite-based free-space optical (FSO) communications. Specifically, we address the design of ...
