ArduinoADKFront450px My experiments with the different variants of the Arduino family. It’s partially a notebook for myself so that I don’t have to reinvent the same wheel over and over again. But I hope, it’s also helpful or entertaining for the curious browser.

As always, have fun exploring;-)

Function tracing for an embedded System via LogicAnalyzer

By | October 16, 2013

OK, I’m trying to play with some embedded systems once in a while. This time around I was trying to implement a relatively fast (1000000Baud) asynchronous serial connection with an Arduino Micro. The Micro is running at 16MHz, so that connection gets close to what should be possible. I implemented my protocol handler and it… Read More »

Robot – North-facing Teddy with CM-900

By | June 5, 2013

 Another experiment with the Robotis CM-900 and my Arduino ADK. This time it’s using a Pololu MinIMU-9 v2 and three Dynamixel AX-12A’s to try to keep the little teddy bear straight and facing North. Sometimes the sensors get a bit confused and the actuators follow to create interesting circle patterns. But overall it seems… Read More »

Robot – Attacking Duck with CM-900

By | May 31, 2013

 I got my Robotis Bioloid Premium Kit and at Maker Faire I got the new open source controller for it, the CM-900. I’m still waiting for some DIP headers, they seem to be out of stock all over the country and DigiKey has a rolling shipment date for my order (seems to be consistently… Read More »

Science Olympiad – Div C – Robot Arm

By | March 15, 2013

This post is about how little differences might cause huge effects in the end. Our team was building a Robot Arm for the Science Olympiad, Division C event. After telling it where the bonus box is located and giving it the start command, it was supposed to be working completely autonomous via a per-determined script… Read More »

Gates and Maglev Track

By | November 2, 2012

Earlier I wrote about my DIY photogates. They work pretty well but there is always room for improvements. So I added a little 16×2 LCD display to the Arduino setup. That way, you can use the large computer-displayed stopwatch or you can rely on the little LCD.  Both work simultaneously and on the same Arduino… Read More »

Arduino-based Photogate Timer

By | October 19, 2012

Mostly for the Science Olympiad – Division C – Maglev event, but also just to learn more about Arduino in general, I tried to build a photogate setup on the cheap;-) I expect the Maglev event’s timed part to be somewhere in between two and three seconds. So even for test runs, a hand based… Read More »

Arduino and LEGO NXT is fun

By | October 15, 2012

OK, I knew about the Arduino platform for quite some time. But I was not sure what I would like to to do with it. But with the next Science Olympiad looming on the horizon and the need to find a cheap photo gate timing system, I had the idea of an Arduino-based system. The… Read More »
