For a recent project I needed to build a large and obvious bar graph display. This was to show the power generated from a bicycle generator. I came up with this design and was pretty pleased with the final results as it is relatively low cost but still pretty visual. It stands 1.5m high and

So you’re here because you want to start learning some of the Arduino Basics… So let’s start with THE most basics… no this “tutorial” is actually a little more basic than what you have in mind. It only requires that you: Have ANY Arduino Board. Have installed the drivers and required software for the board

This simple device simple plays a small tune at a random interval, between 5 and 30 seconds when the lights in a room go off. It can be cleverly disguised inside a tissue box, or inside or under any number of household objects. This is a vary simple project (my first audio project) and requires vary few materials, most of

In this tutorial you learn how to make a blinking clock with a difference! Updated 18/03/2013 Followers of my website would realise that I tend to make too many clocks in those tutorials. Well, I like making clocks… so here is another one. However this time I have tried to make the most simple version possible.

SOS is the commonly used description for the international Morse code distress signal (· · · — — — · · ·). [read more on wiki] Requirements: 1) Arduino 2*) 8 Ω speaker 3*) 150 Ω or similar resistor 4) 5mm RED LED 5) Hook-up wires 6) Any breadboard * Ω = Ohms Step 1:

I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun. The total cost is only $9! Here are a few limitations to RF solution: Communications is

Finally, I finished reading the datasheet. It didn’t give much information about how to connect the motor controller to a micro-controller. I used the simple circuit I found from a post in Pololu’s forum: Using Dual VNH3SP30 Motor Driver with arduino @ http://forum.pololu.com/viewtopic.php?f=15&t=1923. Dual VNH2SP30 Motor Driver Carrier MD03A to Arduino Circuit Diagram I connected

This is a funny looking clock that has that displays time on relatively large 32×16 Bi-Color LED Matrix. It includes also a countdown counter that I find very useful in many situations. Features: Date And time display Temperature display Countdown timer Buzzer notification Randomly changing colors of display Display intensity control (brightness) Aside the fact

This instructable was created to be entered in the Robot Challenge. If I win, the parts will of course, go into robots like this one. Notes on how to include some of the very components in the prize packages are given in the last step. I am 28, so of course, I’m not going for the
