Most Collected: Tip/walkthrough

This is often referred to as STT (speech to text) and TTS (text to speech).  When I started with computers (eons ago) there were crude text to speech programs. … Read more
Controlling Picaxe microcontrollers with a computer or let them communicate
Using a
On general demand (ok, Fritsl asked me...), I will show and explain you how to let several Picaxe microcontrollers communicate with each other or how to control a … Read more

Remote control a set of servos attached to an Arduino board from Processing through the serial port
Using a
This is based on http://www.arduino.cc/playground/Learning/SingleServoExample but extended to multiple servos and with a matching Processing class. To try this … Read more
More Servos, Less Pins, Less Cost
Some time ago I posted a library for running ten servos from an Arduino using just 2 pins. I have extended it to 20 Servos from 4 pins. The library has a variable … Read more

Update! Aparently there is a huge difference in the glue-sticks. Take that into consideration regarding everything in this post. However, I had some of the "bad … 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
Control your Robot with a PlayStation 2 Controller & Arduino

I have been revamping the code for Mr. Tidy and it has grown large enough (23Kb when compiled) to be a real headache to scroll through. I know that some IDE's solve … Read more
Reading Receivers, Driving Servos and ESCs
Hi, I have put together some detailed information on reading from RC Receivers, interfacing with servos and interrupts. Its Arduino based but the principles would … Read more
Turn your servo into a powerful linear actuator
Provided you have the tools and the servo you can built this for under a couple of bucks. The actuator extends with a rate of about 50mm/min. It is rather slow but … Read more
