From the Wemos D1 mini to the NodeMCU, the ESP8266 based boards are by far the most popular platform, among makers and hobbyist, for building WiFi based projects due to their low cost and general ease of use. For today’s tutorial, we will continue our exploration of the most popular of the ESP8266 based boards; the NodeMCU development board and we will […]
We’ve gotten used to seeing “meta clocks,” clocks that use an array of analog clock faces and piece together characters using the hands of the clocks. They’re very clever, and we always like to see them, especially when they come with detailed build instructions like this one does. What’s also nice about [Erich Styger]’s “MetaClockClock” display

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, and we’ll build on those skills in this lesson. Ultrasonic

Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with

For the last month or so I’ve been working on a project involving a NeoPixel, I chose to use a NeoPixel instead of the usual RGB LED strip because I felt that the individual addressable LEDs would be easier to work and create better effects. While this is true I did not take into account the learning curb
Generally, any activity out on the water is more dangerous when done at night. Hazards are less visible, and it can be easy to get into trouble. [Xyla Foxlin]’s party canoe can’t help with that, but it does look the business after dark. The canoe is made out of fiberglass, directly formed onto an existing canoe to make
At first glance, this might appear to be a Rube Goldberg machine made of toys. The truth isn’t far off — it’s a remote-control animatronic story machine driven by its spectators and their phones. [Niklas Roy] and a team of volunteers built it in just two weeks for Phaenomenale, a festival centered around art and digital culture

Original glowing ornament for your Xmas tree. It’s made from brass rods wired by a freeform method and contains 18 glowing LEDs. Step 1: Tools soldering iron solder soldering paste 0.8mm brass rod 18x SMD LED coin battery on/off switch Step 2: The Rings The main challenge here is to create a round shape from
A few weeks ago I made a freeform Arduinoflake. Lot of you loved it. But its magic is not only being freeform but also in the pattern of the LEDs. So I decided to create a PCB version which would be really easy and cheap to make for everyone! It’s the same beauty in a different
The Raspberry Pi compute module is a powerful piece of hardware, especially for the price. With it, you get more IO than a normal Pi, plus the ability to design hardware around it that’s specifically tailored to your needs rather than simply to general-purpose consumers. However, this comes at the cost of needing a way
