Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed ...

This FAQ analyzes the open-drain physical layer and the nuances of register-level addressing to better understand I2C communication.

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, ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate things ...

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 ...

3 pins are required to interface (two I2C and one reset). Adafruit invests time and resources providing this open source code, please support Adafruit and open-source #define SCREEN_WIDTH 128 // OLED ...

Abstract: Intelligent reflecting surface (IRS) is an enabling technology to engineer the radio signal propagation in wireless networks. By smartly tuning the signal reflection via a large number of ...

Abstract: Developing ultra-low-power devices requires low-power components, algorithms, and communication protocols. For environmental monitoring along the supply chain, products may travel a long way ...
