A Wifi platform for $3… who wouldn’t want to play with it? For the last few weeks we have been seeing a lot of awesome projects built around ESP8266 Wifi modules: These modules come in different shapes and colours and can be purchased from the internet for 3 dollars only. They are therefore cheap enough […]
Introduction This project is a simple way of using the Arduino to simulate the behaviour of logic gates. Logic gates are explained on this page. The project does not actually carry out the function of the logic gate, just turns a light on or off based on one or two inputs. Effectively showing the truth
Have you ever wished there was a better way to be notified when your laundry was done? Have you ever forgotten a load in the washer because you couldn’t hear the buzzer and your clothes became smelly and moldy from sitting there for too long? Well, I have and decided to solve this problem by

In this tutorial i will show you , how to make a simple Inexpensive Intrusion Detection(Burglar alarm) using an Arduino Uno board . This project uses the Infrared Emitter-Detector pair to detect intrusion and triggers an alarm as soon as the object crosses the infrared field . ** To see a Similar Project Made with

Practicing the art of time-lapse photography without an intervalometer is doable, but not particularly efficient. And while any decent photo equipment store will be happy to sell you one, you can go the DIY way and build your own intervalometer based on the excellent Arduino platform. Theoretically, building an Arduino-based intervalometer is as easy as connecting an infrared

Last week, we learnt about the basic structure of an Arduino program and took a closer look at the ‘blink’ example. Hopefully you took the opportunity to experiment with code, adjusting the timings. This time, we’ll be writing something from scratch. In fact, let’s make a traffic light. Apart from the basic Arduino, you’ll need:

A microcontroller is a self-contained, but very limited computer — halfway between a computer and a component. The top reasons to integrate a microcontroller into your projects are connectivity and interactivity, and one easy way to get your microcontroller talking with the outside world is standard asynchronous serial I/O. Many devices can communicate this way,
For an upcoming project I needed a pneumatic ram with a closed loop control system so I could position it accurately. Didn’t have the budget for an off the shelf solution, so I bodged one together with an ardunio, a couple air solenoid valves, and a pair of potentiometers. How it works is one potentiometer
What is a tilt sensor? Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. Sometimes they are referred to as “mercury switches”, “tilt switches” or “rolling ball sensors” for obvious
If you ever wanted to integrate RFID functionality into your project, this small tutorial might help you accomplish that. I used the RDM630 module from seeedstudio in its UART version. It comes on a small board with presoldered connectors which fits perfectly on a breadboard. You only need to connect the antenna to the two pin socket.
