Arduino script for MPU-6050 auto-calibration

I while back I did some work on a self-balancing robot using and Arduino Uno and the InvenSense MPU-6050 6DOF sensor. Using the sensor is easy, thanks to Jeff Rowberg’s  I2Cdev library and sample code.  If you look around line 200 of the MPU6050_DMP6 example arduino sketch that comes with the library you will see the following:… Read More »

Arduino Joystick Module Example

In one of my rather frequent eBay visits, I came across a nifty little joystick module, much similar to the analog thumb-stick on the PlayStation 2 controllers. The module is very easy to use with an Arduino uno and only costs a few dollars. Several different versions are available from eBay, Adafruit, Sparkfun and other… Read More »

Free Arduino reference guide

Erik Verberne teaches Information and Communication Technology (ICT) in Netherlands and looked into the Arduino platform in an attempt to enhance his department’s curriculum. He diligently documented his research and is now sharing it with the community. The result is an e-book of over 200 pages full of examples and tutorials, from Arduino and ATTiny… Read More »

Arduino controlled LCD using a shift register and the SPI library

Now that I got my recycled 40×2 character LCD working with Arduino, the next step is to get it to show something useful.  I decided to add it to my Bluetooth Controlled robot  and display data from its two ultrasonic distance sensors (initially). Gradually  more interesting info like battery voltage and wheel encoder data can… Read More »
