The WiFi Shield was delivered by Amazon. The Arduino UNO Rev 3 was found at RadioShack… First you need to load the last Arduino IDE (Ver 1.0.2) it has the necessary library to use the WiFi shield. Tried the examples “Scan for available networks” and “WPA network example” from: http://arduino.cc/en/Guide/ArduinoWiFiShield It works like a charm! …
Anyone who’s started learning about microcontrollers and code could tell you that a good place to start is by looking at the most basic example sketches provided. As often times their simplicity can teach you a lot more than you think. With the Arduino, one of my favorite examples is the blink sketch, which is …
I have loved making projects with Arduinos, but at $30 a piece your projects can get expensive. So I want to show you how you can make your own Arduino from scratch and save money doing it. Make your own Arduino for around $8. For this instructable I show you how to make one on …
Another project I’m working on required a good timer, but the more I read about Arduino, I realized that I couldn’t make an accurate timer using an Arduino that was already devoted to other tasks. The Arduino will always lose time if you perform other tasks. The solution was a Real Time Clock module that keeps perfect …
At University, Alexander Zenger and I decided to realize a weatherstation with an Arduino Microcontroller. We wanted to measure temperature, pressure and humidity. It should be also possible to get every 5 min a value update on an external server. Our basic idea was to develop a weatherstation which is easy to use with different technologies …
I previously worked on an enclosure for the Computer Club server rack, and I thought it would be a good idea to put together a standalone temperature sensor system. Preferably it would interface over the internet so that IRC bots and other programs could talk to it. The project will use four DHT-11 temperature sensors, …
Currently, we are chasing an invisible monster named Corona Virus ( COVID-19 ) and we are going through the biggest health crisis in our time due to a sharp increase in infection cases. One of the main symptoms of the COVID-19 infected person is an increase in body temperature, in addition to other symptoms such as pain …

In this project I’ll display the temperature in a 4 digit 7 segment display (common anode). The sensor is the cheapest you can find so actually the temperature changes pretty easily which makes the display to show always different temperatures. But the idea is to apply this code to other projects with 7 segment displays …

This foot pedal plugs into the Arduino case which plugs into your PC via microUSB cable. Arduino microcontrollers can easily be used to power fun projects like robots and even sending tweets to Twitter but they’re versatile enough to turn up in the strangest of places – like under your feet. We had a question …
