The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

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 ...

Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical ...

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 ...

We'll use an Adafruit library called Adafruit_Neopixel to control the color strip. As of November 2024, our color strip has 55 LED lights and 13 LED pins. WE'll explain how to write a program that 1) ...

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 ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
