Provides a better alternative to the standard motor driver chips
For my first post here I've decided to present a tip rather than a robot build. While working on a my first robot I became frustrated with the selection of motor … Read more
Shows how you can teach a single-axis move by using the Record/Play tactic
Using a
Did you hear about teaching a robot a move but don't know how to do that? Did you ever struggle around to make a polished mathematical way/time function more … Read more
Make servo/whatever controller out of Picaxe 28x1 and control it from Arduino over I2C
While working on my first Arduino project I found out that servo library is not compatible with software serial library which is very bad for my project. So, I … Read more
Recently I got two XBee modules. And after some struggle with serial comunication I finally understand how to share data between two Arduinos. As a start I used 2 … Read more
On Picaxe: sound 1, (110,3) is NOT a good idea, you should allways write sound 1, (110,3) low 1 (you do not need line breaks, just write it as above)   Being used … Read more
Sometimes you want something extra in your servo and you have to build one for the purpose
(If Google video is down, video is here) I like servos! However, sometimes you want what a servo does, but you need one that is special: Very strong, very fast, … Read more
RC-servo to motor conversion   This is a smart little trick i had read about in the magazine "Elektor Electronics" a year ago. In 15 minutes you can turn your … Read more
This might be useful for anyone building self-balancing robots or similar projects
This article introduces an  implementation of a simplified filtering algorithm that was inspired by Kalman filter. The Arduino code is tested using a 5DOF IMU unit … Read more
