If you need an Arduino to shut off from within your Sketch, this is the solution. We will explore wiring the Pololu Pushbutton Power Switch, programming the Arduino to shut off the power, and making the unit “power on” only. The Pololu Pushbutton Power Switch comes in two versions – the SV version geared towards […]
In this instructable, I will show you how to make a sensor that will light up more lights the closer you are to it. Step 1: Placing The Electronics This step will show you where and how to place the electronics on the breadboard Materials: 6-220 ohm resistors 3 green LED’s 2 yellow LED’s 1 […]
What is a solar tracker? A solar tracker can increase the efficiency of a solar panel by up to 100%! It does this by always keeping the panel perpendicular to the incoming rays of sunlight. here’s an equation to prove this: P = AW sin θ P = power generated by the solar panel A […]
Hello, in this instructable I’ll be showing you step by step how to build the TurtleDuino, an object avoidance robot, with an Arduino UNO microcrontroller on board. I designed the TurtleDuino using material from the hardware store (Home Depot) and all the electronics from sparkfun.com and jameco.com. Shopping List: Arduino UNO (Sparkfun.com) Ultrasonic Ping))) Sensor (jameco.com) 2 […]
This Instructable covers the assembly of a circuit capable of PWM-ing (pulse width modulating) a high-power RGB LED strip and programming an Arduino to cycle through a range of colors. In this context, “high power” is 9-12 volts. I will discuss how to mount a transistor to a heatsink and assemble the circuit. I will […]
The project This project follows on from the excellent work by ScotSEA and his Arduino reset program (see http://www.instructables.com/id/CatGenie-Resetting-a-SaniSolution-Cartridge/ ). I had never taken my Catgenie apart as Scott did, but had built a small contact board instead. I had previous updated Scott’s program to so that it output some debugging output to the computer […]
Thanks to: http://jeonlab.wordpress.com/ For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude). I’d […]
Aim: Switch relays from the ethernet or the internet, using your mobile, tablet or computer with a nice graphical user interface. Update V4.06 Please read the below steps to Step 2 if you are viewing this article for the first time. Please go to step 3 for the latest revision which is V4.06 Material: * […]
Have you ever wanted an ultrasonic tape measure, like this Stanley? (See picture). Well, I have but then I am a Lazy Old Geek. I don’t really need one but I thought I’d try to make one. And naturally, I thought of an Arduino. August 2012 update: I just found out the software used in […]
I own two excellent AM transmitters – one is homemade with a single 6888 Tube and the other is a restored old KnightKit Broadcaster. Additionally, I have a high-quality solid state transmitter from SSTRAN that I use to broadcast music to my collection of repaired or refurbished antique AM radios. I desired a top-notch FM […]
