Our first Arduino robot called Rolly in our February issue proved to be a popular project. Powered by an Arduino Uno board it was easy to put together and cost very little. In this project we upped the ante again with our first walking robot appropriately called Stompy. He’s a quadruped a four-legged walker and […]

The last few weeks I was playing with Firebase mostly because I wanted to get familiar with this technology. So at some point I thought that it will be a great idea to connect Arduino with Firebase. Imagine that you have a simple temperature sensor that measures the boiler’s water temperature every few minutes and

Being able to capture sound, store it and play it over and over again never fails to leave me in awe of its pioneers, from Thomas Edison to Alan Blumlein, the British electrical engineer who, in 1931, invented ‘binaural recording’ – what we now call ‘stereo’. (Never heard of him? Blumlein amassed 128 patents in

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

In all my arduino projects I was using cheap 1602 LCDs mostly because… they are cheap but also of the libraries flexibility. Recently I found a nice TFT 1.8 inch 128×160 in a very competitive price and i thought to give it a go. Just $4.5. I had a little bit of trouble to make

TL;DR – I wanted all of my AV components to turn on and change inputs as soon as I started Airplaying music to my Apple TV from my iPhone, so I popped open the Apple TV, wired up a photocell sensor to an Arduino Uno, wired up some Infrared LEDs, wrote some code, and made

This is a simple guide on how to make a Ultrasonic sensor arduino mega with code, an HC-SRO4 Ultrasonic Sensor, a Buzzer, and some leds. The ultimate goal of this tutorial is to use the buzzer and LEDs to display how far the object is from the ultrasonic sensor. Step 1: Materials Needed The Materials

Arduino temperature display I’ve had an Arduino-based weather station since June 2009, but one problem with it has been that there hasn’t been any easy way to display the data in real time without going to the database (or the raw import files) to see what the latest observations were. I wrote a quick web

“M-my lord, it-it’s impossible to locate the ship. It’s out of our range.” – Nute Gunray We recently moved into a new house and as always the first problem to address was finding the optimal place to park cars in the garage. Ideally, we wanted to park the cars as close to the garage door
