Two teams answer questions by pushing their button. They can score an amount of points equal to the random number of lights lit on their button. This requires some strategic choices and luck. When the teamscores meet on the large led strip, they can take away points from the other team. First one to the […]
In this example, you will use your Ethernet Shield and your Arduino to query a Network Time Protocol (NTP) server. This way, your Arduino can get the time from the Internet. Circuit The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via the SPI bus. It uses pins 10, 11, […]
This WiFi Smart Oximeter helps you scan Spo2 and BPM using MAX30102 and ESP32 and display the values on the Smartphone Step 1: In this tutorial, I will explain how to build your own WiFi Based Smart Oximeter using MAX30102 and ESP32 in detail. The project is simple and easy to build. You only need […]
I just got a new go kart engine, i went from 6hp to 10hp. This new kohler engine I got I think was not built to put on a go kart, so I had some trouble finding a way to attach the gas petal. Well after a few days of not really figuring anything out, […]
The Arduino system offers an easy and open-source method for programming microcontrollers. Normally this means using a serial cable or USB cable attached directly to the microcontroller project. But what if your project is floating in a weather balloon, glued to the bottom of a swimming pool or baked into a loaf of bread? It would be […]
Last year the comedy sketch show ‘Portlandia’ made fun of an arts and craft trend, where craft artists would take ordinary items and ‘put a bird on it’. I fell victim to a similar trend in the geek crowd: Take an ordinary silver item and add LEDs to ‘put a cylon in it’. 🙂 When […]

Lots of people celebrate Halloween by making pumpkin sculptures most of them only just carve a scary looking face from the pumpkin and place. in this tutorial, I am showing how to give a more awesome effect to your pumpkins. here I added human/obstacle detection, smoke and lights. let’s scare them all Step 1: Components […]
Measuring the consumption of a resource that has units by volume can be more tricky than it sounds. Use of resources such as water, gas, and even electricity is typically measured by gauges that determine either instantaneous flow rate or cumulative volume over time. Both techniques have problems: measuring flow rate at frequent intervals allows […]
This project is loosely inspired by the laser harp of Jean-Michel Jarre. Instead of lasers however, it uses eight SHARP infra-red distance sensors, the variants with the longest range of 35 to 40cm. These sensors are laid out in a row to provide rows of 8 notes at 3 different height levels giving a total […]
