Especially for low numbers of switches in non-microprocessor controlled devices. If the number of buttons you require on your front panel numbers less than 16 then this is how you get a clean button press. You can use CMOS or TTL but the component values change. I'll show the component values for CMOS but it should be noted that the values should also be sweetened to taste.
Figure 1 shows the basic arrangement. However CMOS and TTL don't like smooth transitions. There are a number of parts in both CMOS and TTL. Above is the full debounce circuit using one sixth of a 74C14 package.
Arduino and iOS. Android and Arduino. Arduino. Labviewduino - A LabVIEW library for controlling an arduino through the firmata protocol. Indrotuction A basic library that permits controlling an arduino through the firmata protocol.
The current version is developed and tested with the arduino ver0021 software. The purpose of this library is to make it easy to LabVIEW developers to connect their code to the real world using the arduino hardware. My goal is to use this subvi of library through labview to make arduino as a cheap DAQ device. If anyone also interested in contributing towards this direction let me know. developer guide 1.

It's a low-profile through-hole version, with a simplified design. It's based on a ATmega328P microcontroller, and comes pre-flashed with the Arduino bootloader. Open source design, with bare basics hardware. Diavolino is sold as an easy to assemble "through hole" soldering kit. Intro / Home Page.

LCD Smartie - A free open-source LCD program! USB development board with a custom scriptable language. SigLab is an open source USB development board that takes commands from a small program that runs Python-like scripts.
The hardware is basically a PIC18F2550 breakout board, but the firmware makes it easy to get started using the familiar desktop scripting language. SigLab is a combination of open hardware and FOSS (free and open source software) projects to provide easy to use and full featured scriptable USB interface for digital electronic experiments. SigLab USB interface consisted with Microchip’s PIC18F2550 microcontroller unit and it provides 14 bidirectional (digital) I/O ports for external interfacing.

RBBB_Instructions_06.pdf (application/pdf Object) Web-Connected Light Sensors With Pachube & Arduino. Two of the more interesting products in the 'Internet of Things,' a.k.a. real world objects connected to the Internet, are Pachube and Arduino.
We profiled Pachube (pronounced "patch-bay") in May; it's an open source platform enabling you to connect sensor data to the Web. Arduino is an open-source electronics prototyping platform, which we briefly profiled in February. So far both services have spawned some geeky and quirky - and in truth not overly useful - trial apps. For example Pachube has been used to monitor house plants and a recent Arduino creation monitors a teapot's tea level. However this is not to undersell the potential of either service - it's just that both are currently in the experimental stage. It's fun to look at what is being developed now, because it gives us a glimpse of the Internet of Things of the future.
Morgellon from The Daily Duino set up two light sensors in his room - one mounted on the wall and the other taped to a window (facing outside). Arduino - HomePage. Perfduino: Build Your Own Arduino Microcontroller! This how-to takes you through all the steps of making your own arduino on a perfboard or perfduino!
Arduino microcontrollers are great for learning about physical computing and are very useful for rapid prototyping. Arduino’s simple programming language makes it a favorite of hobbyists and diy-ers around the world. Because arduino boards range in price from 30 to 70 dollars, it can be very cost effective to make your own.
