In this project, we will learn how to use a speaker (peizo sounder) and use switch button to change the pitch of the sound. Sorry about this one, you might find it a bit difficult to digest at first, and I didn’t realise it’s actually harder than it sounds. Anyway, spend some time on the code,

7-Segment LED Display is a very useful component, but also a very confusing and difficult piece to use for beginners. It won’t be difficult once you get it working for the first time. This is what you will get at the end of the tutorial (part one): It basically consists of 7 LEDs, (8 if include

My First ever Robot. It tracks objects using Infra-red sensors, and has basic AI that follows and avoid objects. I will describe the how I made this robot, and upload some videos. Version 1 (16 Dec 2011): —————–The components used ———————- I actually planned this robot before making it. I didn’t use all the parts

Arduino HC-SR04 The Arduino HC-SR04 is different from most of those commonly seen on the market, which have 4 pins compared to 3 pins. But the operation principle is the same, transmit signal, and depends on when the signal is received to estimate the distance. Arduino HC-SR04 not only inexpensive but also practical, use a

Arduino Hexapod Robot Design I will show you how to build an arduino hexapod robot, from building the body, to how to implement the algorithm. To learn about the implementation of the algorithm, read this first, if you are not sure what is IK, read this.

[INTRO] This past semester, I decided to build a GPS receiver with an iPhone app that tracks it for my semester project. Here is a step-by-step tutorial to show you how you can build your own. [OVERVIEW] Architecture of my Real-Time GPS Tracker project. I’ll be using the diagram above to explain how the project

MaKey Makey is a project created by Eric Rosenbaum und Jay Silver. It’s an Arduino based keyboard. A very special keyboard, because you can use apples, bananas or Play Doh as keyboard keys. Sounds strange, but it works very well. How it works: The trick is using a very high resistor on the Arduino input (10..50MOhm).

In this week’s arduino tutorial, we take a bit of a detour and focus on some key elements of electrical engineering design that we’ll be using in future episodes. Included amongst these topics is Ohm’s Law, current-limiting resistors, pull-down and pull-up resistors, voltage dividers, potentiometers, analog inputs, and voltage regulators. If you’re yearning to learn

As promised, this week brings another communications tutorial! In this video, we’ll use both the serial and processing knowledge that we gained last week, plus an I2C enabled temperature-sensing IC. We’ll use processing to generate a pretty room temperature display on your computer screen. If you are new to processing, they have an excellent
Arduino I2C and Processing Continue Reading
Update (6/7/2012) – I’ve had to disable comments on this post, because it is being targeted by spam bots for some reason. Please use the contact page if you have a question about this topic. In this week’s arduino tutorial, we’ll be taking a look at SPI device control using the arduino. Specifically, we’re going
