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 […]
down vote favorite I have a minor issue with my ECG. When I poke at the leads, I get a reading. But when I hold the leads or place it near my heart, I don’t get anything. I’m pretty sure this is hardware related, but I don’t want to completely rule out a potential software […]
1. Overview The Wixel shield seamlessly enables a wireless link (with a typical range of ~50 feet) to replace your Arduino’s USB interface, which means you can use the standard Arduino computer software to: wirelessly program the Arduino (this feature is not available with the Arduino Leonardo or the A-Star 32U4 Prime). wirelessly debug sketches with […]
Today I want to make a LED Scroll Bar as the above picture showed. Ten LED strips can flash in different effects by using a control board. Required Components LED strip, Arduino Nano, Dupont line and a control board. So, how to make a LED Scroll Bar? Step 1) Cut the LED strip into 10 […]
This video shows the Traffic light and pedestrian crossing I’ve implemented with an Arduino. It’s a reproduction of the crossing near my home, timings taken from a video of it. Incidentally, I produced the diagrams for this using a product called Fritzing. It’s a nifty piece of software that allows you to draw a breadboarded version of […]
Water is basic need in every one’s life. Saving and proper usage of water is very important. Here is an easy project which will give the alarm when there is rain, so that we can make some actions and save the rain water. As a result, we can increase the water levels of underground water […]
This project is a RC quadrotor helicopter (quadrocopter, quadcopter, quadricopter, etc). It’s a RC helicopter that uses 4 rotors. You need some pre-requisite skills: How to use Arduino, enough to get started Soldering, wiring, basic electronic skills Basic hand tool operation A quadrotor helicopter flies with 4 spinning propellers on a + shaped frame. When […]
Open Fethercoin ATM is an open-source automated teller machine for education and experimentation. Based on John Mayo Smith’s OpenBitcoinATM which can be seen in action here A “voucher” is printed containing a private key QR Code that has been pre-loaded with the correct value of Feathercoin for the denomination deposited during the setup stages. Designed […]
I spend a fair amount of time zipping around town on my scooter, and thought it would be cool to add a voltage monitor to warn when the battery might need recharging. Waiting until the electric starter no longer works is somehow lacking. So after an evening with an Arduino Duemilanove, I had a simple […]
Schematic Diagram You may remember, if you studied electronics as part of your science course at school, that there is a specific way of drawing circuit diagrams. Each component has a particular symbol (which may vary slightly depending where in the world you live) that allows anyone to look at the drawing and build the […]
