Abstract: This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are controlled by an Arduino-based microcontroller that ...

Chemists in South Korea have created a stable color-changing sensor that displays an easily quantifiable response to the pH of its surroundings. Published in Microsystems & Nanoengineering, Dong-Hwan ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...

Reading analog clocks is a pretty straightforward skill to learn. However, if you’ve already learned to read and don’t want to pick up the extra skill, a word clock is a perfect ...

Soldered Electronics has made ESP32-based e-paper displays for years, starting with the launch of the Inkplate 6 in 2019. The Inkplate 13SPECTRA is their latest model based on an ESP32-S3 WiFi and ...

This program written with Arduino Code running on ESP8266 (Wemos D1) is just a test to access, read status and control Tuya compatible WiFi Smart Devices (Plugs, Switches, Lights, Window Covers, etc.) ...

Abstract: In recent years, many applications using paired RGB and Near-infrared (NIR) images have been proposed in camera vision and image signal processors. With the current progress of the CMOS ...

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 ...
