The Gravity: I2C Oxygen Sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. With high anti-interference ability, high stablility and high sensitivity, this arduino-compatible oxygen sensor can be widely applied to...

Apart from the simple and fast development of graphics applications, a larger display has been added to the pool of benefits of working with 4D Systems displays. New 9” module with resistive or capacitive touch panel and with adapters for Raspberry Pi and Arduino. Intelligent...

  644 Narrow and 1284 Narrow are small, simple, ATmega644/1824-based boards, which are designed to improve small footprint Arduino projects. The Narrow board enables two to eight times more flash and RAM resources and ten more digital I/O as compared to an Uno/Nano, plus total...

Fonts sourcing/creation, usage and management, are some of the major challenges firmware developers face with projects where the display (TFTs, Epaper displays, etc.), is a critical element of the project's performance. From access to clear and good looking fonts to managing the size of...

We've seen several Security-based hardware projects from Koko (@justcallmekoko) in the past, including the Masterkey keylogger which we explored a few days back. Looking through his projects on GitHub today, I stumbled on another security-based project called the Tinyduck. A cheap...

Made popular by the Arduino based on it, the Atmega328p has become one of the most popular microcontrollers around, thanks to the ease with which it can be programmed using the Arduino IDE. Either as a direct clone of Arduino boards like Uno and Nano or as a new board with an entirely...

For a while now, most popular ESP32-S2 boards available in the market are produced by Espressif Systems. This includes the ESP32-S2-Saola-1 and ESP32-S2-Kaluga-1. However, there is a new LilyGO TTGO ESP32-S2 board for sale. This micro board is much the same to the ESP32-S2-Saola-1...

At the heart of any embedded electronics device, either on a DIY or professional product level is a microcontroller. They run the codes/firmware that helps developers obtain inputs from sensors and tie it to actions executed through actuators. While they are usually developed as...
