Below you can see a “CIE1931 Fade” Arduino sketch by Tom Igoe (https://tigoe.github.io). The sketch takes input from a potentiometer and produces a fair LED fade, using the CIE1931 perceived lightness ...

What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated p… ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Two encoders are used to recreate the famous Etch-A-Sketch interface, hooked up to an Arduino Nano that then communicates encoder data to the Pi over I2C, due to the limited GPIOs available.

The Etch a Sketch toy has gone more or less unchanged for over 60 years, but if you’re handy with a soldering iron you can build an upgraded version that ...

There are many ways to do this, but on the Intel® Edison board, I found that the easiest way is using the /etc/init.d directory. If this is your first time using init.d for start-up scripts, you ...

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

Da Vinci, the Arduino-Powered Etch-a-Sketch Patrick McCabe’s latest creation is a delightfully ironic combination of high-tech and low-tech that is sure to please.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
