Introduction Disclaimer: I am not an expert in any of this. There is lots of information online regarding such designs. Although this setup worked for me, do not trust any of my calculations. Please work all this out for yourself and consult many other sources, or it may spontaneously burst into flames. The contraption is […]
What it is… Type: Graphical (128×64) monochrome LCD with LED backlight Interface: Serial / SPI This is a good time to read the datasheet Available from: Adafruit, of course! Introduction: This mini-tutorial will go through the process of setting up a ST7565 LCD. These LCDs are graphical which means they can display pixels, not just […]
If you’re like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects. The problem was that I’m such an electronics newbie that I didn’t know […]
This will teach you how to make a very simple 1×10 array of LEDs on a breadboard controlled by an Arduino Uno to make the LEDs blink and flash in 10 different patterns. Link to notebook for project: https://docs.google.com/document/d/1YP4p11SbDNOnM7mDn-sRjJLnxGPj6o0DkrFZnznVMvk/edit Link to YouTube video of LEDs in action: http://youtu.be/waaNSYbWn2Y Step 1: Insert LEDs into Breadboard Insert […]
This instructable shows you how to use NES controller in Atari 2600 or ZX Spectrum (with Kempston Interface) with the aid of an Arduino. Step 1: Background talk I have recently acquired a couple of Atari 2600s and a bunch of joysticks. Both consoles were working but all of the 5 joysticks were damaged beyond repair. Indeed, […]
This Instructable shows you how to build a four-gang outlet box in which each outlet is controlled via an Arduino (or any other TTL level signals). It differs from the other relay boxes in that it uses no circuit boards and has very few parts (one chip and 4 relays). Step 1: Assemble Materials/Review Plan Tools […]
There are a lot of Twitter feed readers around the Web that use Arduino AND a PC to display twits on LCD displays or whatsoever. Then, I decide it was the time to design a solution for performing the same job WITHOUT A PC, and here’s the project. In a simple equation: Arduino + Ethernet […]
Bored of blinky lights that blink in response to time? Make them blink with space instead! This instructable shows a quick method for connecting LED tree decorations to a Geiger counter via arduino, so that the lights blink between different strings each time radiation is detected. It’s nicer to think of this as “cosmic rays” […]
We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite […]
Forward: This instructable was originally posted at http://www.instructables.com/id/How-to-make-LED-Fader-using-Digispark/ My students and I developed it into this exemplar, for which they received a very good mark. Viewing the following video may leave you with a sense of too much too fast. Please continue to read this Instructable which documents my students’ Tanner and Amanda’s culminating math […]
