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

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 ...

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 ...

Clocks come in many styles and sizes, with perhaps the most visually pleasing ones involving marbles. Watching these little spheres obey gravity and form clearly readable numbers on a clock has ...

[wyojustin] was trying to think of projects he could do that would take advantage of some of the fabrication tech that’s become available to the average hobbyist. Even though he doesn’t have any ...

Designed for M5Stack Atom, AtomS3, and AtomS3R series IoT controllers based on ESP32 or ESP32-S3 wireless SoC, the Echo Pyramid base enables smart voice ...

No one likes getting up in the morning — unless you're an early bird — but a good alarm clock makes waking up just a little easier. We've tried dozens of alarm clocks, from the gentle, gradual ...

Hook up the Adafruit BME280 to your Arduino Giga R1. You can use a prototyping shield to simplify connections. Connect the antenna to the Arduino Giga R1 WiFi if you haven't already Connect the ...

Composite video output from M0 microcontrollers: Circuit Playground Express (not 'classic'), Feather M0, Arduino Zero, etc. Requires latest Adafruit_GFX and Adafruit_ZeroDMA libraries. Gator-clip ...
