Quadcopter Multiwii Settings for an Arduino Mega with IMU

Posted on January 4, 2015 04:28 by Experimentaltechnik Comment

The multiwii code is very large and can be quiet overwhelming at the beginning(at least for me it was), but once you know that all the important settings are made on the config.h tab it becomes more overseeable. In the following I show the settings that I have chosen so far. Here is the video in which I tested them: http://youtu.be/ad5JCKX0C40
I can`t guarantee that the quadcopter will fly with them, because I didn`t try it yet. When I change something I will update this page.

Arduino Mega Protoshield Review

Posted on December 27, 2014 20:12 by Experimentaltechnik Comment

This is a protoshield(short for prototype shield) for an Arduino Mega. They are sold for around 3 Euro and in my opinion it`s worth it compared to the afford it takes to make a shield like this by myself. All the pins, the two leds and the reset button are brought to the top and labelled correctly. In the middle is a lot of room to solder electronic components onto it. In my case I want to solder a 10 degree of freedom IMU and some headers onto it and use it as a flight controller shield for my quadcopter.

How to control a SimonK ESC and brushless motor with an Arduino

Posted on September 11, 2014 18:25 by Experimentaltechnik

Here I`ve made a short video about how to control a SimonK ESC with an Arduino. (The SimonK firmware was already on the ESC when I bought it.) It can be controlled like a servo.

the code:

My next project: Making a Rotational Speed Sensor

Posted on September 6, 2014 16:00 by Experimentaltechnik Comment

I want to make an universal useable rotational speed sensor device. My first experiments with an infrared LED and an infrared diode which can be seen in the picture were promising. I could measure the RPM of a brushless motor and also of a propeller, just by the difference of reflections of the IR Led on the motor or propeller that got recognized by the IR diode. The Arduino code is already finished. The circuit is very simple, I didn`t even need an OpAmp.
A video about this project will come in the next days, but before I make that, I will solder everything together nicely and add a LCD to show the rotational speed.

Arduino: How to control a DC motor (Lego Technic) with a mosfet

Posted on September 2, 2014 02:20 by Experimentaltechnik Comment

In this video I demonstrate an easy way to control a DC motor with an Arduino and a mosfet.
The sketch used in this video can, as always, be copied from here under the video.

Arduino: How to control LEDs wireless over 433 MHz

Posted on September 1, 2014 08:53 by Experimentaltechnik Comment

Here is a short video about how to control 2 LEDs with 2 buttons wireless with a cheap 433MHz module and the virtual wire library. This was a bit tricky, therefore worth making a video about it.
You can download the sketches and breadboard pictures from below.

How to multiply your Arduino UNO for less than 4 dollar

Posted on September 1, 2014 08:24 by Experimentaltechnik Comment

In this video I show and explain how to easily get and use several Arduino UNO microcontrollers Atmel 328P-PU without the need to use the Arduino UNO board, except for uploading the sketch.
It became kinda obsolete, after I found out about the even cheaper Arduino Pro Minis. But anyway, it was a nice project and gave me some more understanding of the Arduino hardware.

Arduino: getting started with a 10 dof IMU

Posted on September 1, 2014 06:01 by Experimentaltechnik Comment

In this video I`m showing how I`m getting started with a 10 degree of freedom inertial measurement unit containing an accelerometer ADXL345, a gyroscope L3G4200D, a magnetometer HMC4883 and a barometer BMP085 on an Arduino UNO.

Matrix Keypad – reducing the pins from 8 digital to 1 analog on Arduino [How to]

Posted on September 1, 2014 05:24 by Experimentaltechnik 2 Comments

This is my second video. A tutorial on how to use a matrix keypad with just one pin of an Arduino. One reason why I started my Youtube channel with the keypad review video was that I knew that I could make this video afterwards. This was one of the projects that I tinkered with when learning about the Arduino soft- and hardware last year.
You can download the sketch and the library here: AnalogMatrixKeypad
