This embedded C project interfaces an HTU21D sensor with an SSD1306 OLED via I2C using ATmega328P (Code::Blocks/AVR-GCC). Implements bit-banged I2C, CRC-8 validation, custom 5x7 font, and low-power ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Embedr is an AI-powered Arduino-like IDE designed to simplify development for Arduino-compatible microcontrollers. It looks ...

In this study, we demonstrate fabrication of an evanescent wave fiber optic humidity sensor based on PEG-PMMA microsphere film as moisture-sensitive material. A three dimensional stacking structure of ...

Circuit and Working Fig. 2 shows the circuit diagram of the humidifier. The system is built around an Arduino Uno (MOD1), a 5V SPDT relay module, a humidity sensor (DHT22), an ultrasonic humidifier, ...

An ultra-sensitive optical fiber humidity sensor based on an extrinsic Fabry-Perot interferometer is proposed and experimentally demonstrated in this paper. The Fabry-Perot cavity is constructed by a ...

Whether you want a rugged, take-anywhere speaker for the beach or the centerpiece for a multiroom sound system, these are the top Bluetooth and Wi-Fi speakers we've reviewed.

In addition to CO₂, it monitors temperature and humidity, providing a comprehensive overview of indoor air quality." Those sensor proved accurate, too.

This lab focused on sensor interfacing using the Raspberry Pi 5 and Sense HAT. The primary goals were to control the LED matrix to display messages and retrieve real-time environmental data ...
