TriEmbed. What’s the password? Arduino + Keypad. Keypads are everywhere; on your cellphone, on your TV remotes, on your stereo and now on your Arduino. Wait…. Why do you want a keypad on your Arduino? Well it’s a pretty useful device to input numbers and letters (example: telephones), it can also be used for security measures like a keypad door lock, and it’s prefect when you need a low-cost and accessible interface for your next idea. After all, It wouldn’t be practical to use a single button or a potentiometer to input your Pin on an ATM. So for this tutorial, we will be going over Sparkfun’s 12 buttons keypad (0-9, #, * ), and get you all set up with some code and schematic too.

The buttons on this particular keypad are setup in a 3X4 matrix format so we only need 7 pins to detect the pressing of 12 keys. Hooking it up So this wiring example looks really confusing, but it’s not. Code For this tutorial we have 2 Arduino projects.

Matrix Keypad library This page last updated September 04, 2013, at 11:42 AM by gratefulfrog This tutorial is based upon theMatrix Keypad library Navigation What is it? The Keypad library allows your Arduino to read a matrix type keypad. You can scavenge these keypads from old telephones or you can get them from almost any electronics parts store for less than $5 USD.

They come in 3x4, 4x4 and various other configurations with words, letters and numbers written on the keys. Download latest(This includes four example sketches.) Identifying the keypad pins First you need to get a piece of paper and draw the right hand diagram as you see it below. Procedure Connect your Ohm meter leads to pins 1 and 2. Notes on using the library The library is non-blocking which means you can press and hold the key all day long and your Arduino will continue processing the rest of your code.

Example Troubleshooting 1. 2. 3. Modifying the library More information on using and creating libraries. Yet another laser cutter. When my EPSON 830U decided not to work for me anymore (printing heads clogged) I thought I could make some use of the still working mechanics of the printer. It's based on a couple of stepper motors for both axis of motion (print head and paper feed). So I replaced the original power supply and drive electronics for an arduino board and an stepper motor driver from Adafruit industries. Now I could move the printhead anywhere on a page. Next step was to add a laser on the printhead and to control it using a PWM output from arduino (so laser power could be modulated from the computer).

Though it only cut thin back color cardboard, it has may uses. Data format is very simple: each line contains a sequence of integer numbers separated by blank space. If you have an old EPSON printer, you may want to give it a second thought before putting it to the trash. Video was shot by taping an iPod to the printer's head. 0. Motivation When I bought such a motor control shield recently, it came as a kit without any instructions. I could find the circuit diagram and list of parts on the Internet after some searching, but almost nothing on assembly and how to control it. Therefore I decided to create this page to share with the community what I learned so far.
