About two years ago, I built a big 120 face LED geodesic dome that plays music with a MIDI output. However, it was a difficult build and the sensors weren’t completely reliable. I decided to build the Bucky Touch, a smaller version of my geodesic dome that is easier to construct and has upgraded capacitive touch sensors. […]
Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N*(N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects. Throughout […]
Hello there! Fellow electronics enthusiasts, I am quite sure we all make some or other projects, as a part of our learning experience or academics. We sure would want to display some data present on our micro-controllers, from sensors or simply display some message, so here is a quick tutorial about OLED displays, in which we […]
Spooky teddy is a 2-part Halloween decor. The first part is the teddy bear that has a 3d printed mechanism that can rotate with an Arduino UNO and a solenoid. The second part is a self-rocking chair powered by an Arduino nano and a solenoid attached to the bottom of the chair. The two parts […]
Once I saw a beautiful box of chocolate in a store. And the thought occurred to me to make an awesome gift out of this box – an animated box with chocolate. What we need: Сlear plastic chocolate box 9V battery Battery cable adapter uSD 1GB Arduino Uno TFT Shield for Arduino Step 1: Step […]
If you are not familiar with ESP8266 micro controller, I really feel you have been missing out! These things are incredible: they are cheap, powerful and best of all have built-in WiFi! ESP8266 started their journey out as a WiFi add on board for more traditional Arduino boards but shortly after, the community realized the […]
Eyes on the prize, Violet. Eyes on the prize! Get ready for a candy-grabbing face-off with your family and friends with this classic arcade game – the candy claw machine! But this time, it’s going to be a bit different – first, it’s going to be at your home, and second, you’re going to make […]
Zener Diode Tester is controlled by Arduino Nano. Tester measure breakdown Zener voltage for diodes from 1.8V to 48V. Dissipation power of measured diodes could be from 250mW to a few Watts. Measuring is simple, just connect diode and press button START. Arduino Nano gradually connect range of voltages from lower to higher, in four […]
I made a weather station connected to internet. It measures temperature, humidity, pressure, rainfall, wind speed, UV index and it calculates few more important meteorological values. It then sends this data to weathercloud.net, which has nice graphics and UX. It also has a weather webcamera. It cost me around 140€. I made this station as my […]
Making reverse loops can help in model train layouts to change the direction of trains, which cannot be done with turntables. In this way, you can create single-track layouts with a reverse loop on each end to run trains without any pause or interruption. So, without further ado, let’s get started! Step 1: Gather All the […]
