With this you just type the text you want on your computer and your 5×5 dot matrix shows the message. Used: ~25 leds ~Arduino uno ~5x 100ohm resistor ~and a bit of skripting It took me a while to figure this all out but in the end it was quite rewarding. not really practical though. […]
This Instructable is part 3 in an Intro to MaxMSP series I’ve just finished teaching atWomen’s Audio Mission in San Francisco. Part 1 is an introduction to MaxMSP and MIDI, part 2 is intermediate Max and Audio, and this Instructable is all about interfacing MaxMSP with hardware. I recommend at least skimming over my last two instructables before […]
The mailbox phone alert sends you a text whenever you get mail. I remember anxiously checking my mail multiple times a day during the spring of my senior year of high school as I awaited letters back from colleges. Nervously, I would walk up to the mailbox. My heart would skip a beat as I […]
I design and create this Palm Arduino V3 prototype PCB, as I was tired of recreating Arduino Compatible on perf board every time I prototyping a new project, especially when I had to spend a lot of time tracing the wiring to see that I made the right connection. I design this Palm Arduino (version […]
Adding an LCD display to Arduino projects can add real value but the cost of doing so can be significant. Not a financial cost – you can pick up 16 (characters) x 2 (rows) LCD for as little as £3.50. The cost is the pin count it can take to drive them. Using the built-in […]
Arduino Mega Introduction: An Arduino Mega is an electronic circuit board known as a microcontroller that uses ATmega1280. This offers 54 pins, which can be set to input and output variations, and 14 for analog and pulse output signals. There are also 16 analog input pins for reading analog voltage levels. The board has 4 […]
I saw the Open Hardware Pulse Sensor at thought I’d try to make it at home. Took me awhile, but here’s my bumbling process. Step 1: Pulse Sensor — Overview I’ve been working on re-making the the Open Hardware Pulse Sensor so it’d be “easy” to send off to OSHPark and make at home. I’m not sure but I […]
Last month, I made a XY-plotter by Makeblock and use it to built a Drawing Robot. This Drawing Robot was built with two Linear Motion Shaft D8x480mm, two Long Beam0824, the timing belt, two stepper motors, two stepper motor driver, and a micro-controller Arduino. You can send a picture from the phone or you can […]
For this project, I was inspired by my best friend. She had been wanting some disco-fabulous armor-inspired wearable technology for music festivals and costume parties for some time. I took a pair of construction/gardening knee-pads and turned them into glitterific shoulder pads that shine bright with 50 LEDs that are Arduino controlled! This project was […]
When we’re working with LEDs, we often like to control their state (on/off), brightness, and color. There are many, many different ways of going about this, but none are as compact a solution as the WS2812 RGB LED. In its tiny 5mm x 5mm package, the WS2812 includes 3 super bright LEDs (Red, Green, […]
