This sketch is very similar to ttMoveDouble except it’s using the controlP5 GUI library to control how big the circles grow every time a sensor is activated. controlP5 is really cool, and I encourage you to check it out!
I spotted a post by Lior Hass on Hackaday a little while back where he described his Alarmino project where his alarm system now connects with an Arduino and a custom board to simulate the phone line and interpret Contact-ID protocol. He could then get the system to SMS him in the case of an alarm. In his case, he did this in lieu of using a central monitoring service and it only reported events that would have been sent to the central monitoring service. But suppose someone was using a central monitoring service and just wanted to augment the system with additional potentially detailed and configurable notifications.Scott's After Hours Projects
This is a project that I have been working on a few months now and I have completed its build very lately. The main processor used in this project is an Arduino MEGA 2560 which is interfaced with a real time clock called the DS 1307 chip (which gives you the time and date).
Arduino meets Ecology and Christmas. This integrations uses Arduino as a Twitter trigger for the lights, so if you tweet one of the keywords: PACE, AMORE, SERENITA’, FRATELLANZA, TOLLERANZA, GIOIA, SPERANZA, SOLIDARIETA’, FELICITA’, PEACE, LOVE, BROTHERHOOD. This is an Italian Project and the Tree can be found in Lonate Pozzolo near Varese.
My old keypad GDO gave up the ghost a while back so I decided I'd undertake a new Arduino based project. I ordered a Velleman 12 key keypad from some supplier. I don't remember who, but I did a quick search and found a bunch of people selling them for about $5 US so this is still a viable project.
Cooking Hacks, the open hardware division of Libelium, a wireless sensor networks platform provider for Smart Cities solutions, has released a new e-Health biometric sensor platform to give the maker community tools that use Arduino and Raspberry Pi open source hardware platforms to monitor patients’ conditions.
I’ve been on mission lately to design a handheld bluetooth game controller. I’ve made a prototype in the past but, it never was really usable as a gaming device. Although the concept worked well the form factor was not quite there.
Ok this is not a project 100% core Arduino, because it uses custom hardware and only the bootloader of Arduino. But it's a game controller , programmed with Arduino software.
This is similar to Processing + Arduino 01, except it involves TWO PIR motion sensors instead of one, in order to control both of them without having to type the same code twice, I used a custom function.
Ever since I was little I always had a fascination with walking robots. It was extremely interesting to observe these robots move, walking made them seem much more lifelike than their wheeled or stationary brethren. As a child, I would always ask for the latest robotic toys and drooled over robotic pets such as the Sony Aibo which was unfortunately out of my budget (and my parents' Christmas budget). Now,, with a degree in mechanical engineering, and the tools and knowledge necessary, I've finally started building my own quadruped robot.
A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems – a PID is the most commonly used feedback controller. A PID controller calculates an "error" value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize the error by adjusting the process control inputs.
