Tweetbot … the code
Twitter Controlled Robot
I presented this project at the 28th Montréal Python meeting. I posted the slides of the presentation in my previous post here. The objective of this project was to demonstrate the use of pyserial and XBee to wirelessly control a robot. This project was also my first attempt at using the Tweepy library. The...
Montreal Python #28
Today at 18:30h, I’ll make a short presentation at the 28th edition of the Montreal Python. I’ll present my PyGame Wireless Game Controller and a robot controller by the web. More details about the presentation on the Montreal Python Website: http://montrealpython.org/2012/03/montreal-python-28-lithographic-lobotomy/ You can get the slides of the presentation here: https://docs.google.com/presentation/d/1KTqljkl-fSZyuhXonCrQN10HsEFdp5AsavMEvj8bdRU/edit#slide=id.p...
Atmega328 Vcc pin
I received a comment from “N00B” on my Build an Arduino Clone post pointing out a mistake I made by connecting 5V power to the pin #6 instead of pin #7 of the Atmega328 micro-controller. He was right and I changed the text of the article from pin #6 to pin #7 but, what...
The Maker Faire World in New York
Following the Open Hardware Summit I went to the Maker Faire World in New York city. This event was held in the same location as the OHS, at the New York Hall of Science. 3D printers were all over the place! Of course there was the 3D printing village where Makerbot, Makergear, Ultimaker, Botmill...
Parametric Arduino Case
When you make a project using an Arduino board, you often need a case to attach the Arduino onto your project. This small project is my first attempt to make such a case that can be adapted to all my projects. To make it parametric I am using the OpenScad application. OpenScad is an...
Arduino Motor Controller Using an L293D Chip
Controlling DC motors is at the heart of many robotic projects. Servo motors are sexy but DC motors are cheap and a lot more useful to control wheel based robots. In this article I’ll display a “robot shield” circuit that allows you to use cheap motors to drive your robot. Wiring This shield has been built...
Wireless Arduino/XBee Game Controller
For this project, I keep the same controller as in the previous post but, instead of controlling a servo motor through a second Arduino, I will use it as a game controller. The game will be played on my desktop computer. Since I am not very good at writing games, I downloaded the PyGame...
A simple Arduino Task Scheduler (video)
I uploaded a new video to demonstrate the task scheduler in action. In this example I am driving two servo motors, two LEDs and a print-out to the serial port. You will find more details on how to use the task scheduler on my previous post. The code is available for download from my...
A Simple Arduino Task Scheduler (1)
My motivation to write a task scheduler framework is to help me faster develop new Arduino projects. In most projects, we repeat the same tasks over and over before getting to play with the new stuff. You can jump into the code right now by downloading it from my github account at: https://github.com/pchretien/scheduler. ITask...
