The Internet provides resources for almost everything, even videos about the I2C bus. Or at least about appliances using the I2C bus for more or less useful things.

This is what we have found:

  • ZEROPLUS--I2C Bus Measurement

  • LEGO NXT quadcopter seesaw demo

    An arduIMU runs an AHRS program, and sends orientation information to the NXT via the I2C bus. The NXT runs a control loop and sends motor commands back over I2C. Finally, the arduIMU spins the motors. The large oscillation halfway through the video is me giving one arm a push off screen. The controller is tuned to be less agressive for the safety of the nearby interns : )

  • SAA1064 Arduino bar graph

    A quick demonstration of the SAA1064 LED display chip (connected to bar of 16 LEDs), controlled via I2C by my Arduino. The '1064 can control 32 LEDs with the addition of a capacitor and two NPN transistors. The yellow and green wires are the I2C bus... The bus is shared with a DS1337 real time clock circuit - most of the other junk between the Arduino and SAA1064. The big bunch of blue and white wires are LED cathodes. The bar is displaying analog voltage from the potentiometer in the foreground, which is read and interpreted by the Arduino. The graph's brightness (and the LCD's as well) is controlled by ambient light, as read by a TEMT6000 sensor (the doodad I cover with my finger and shine a flashlight on in the vid), also read and interpreted by the Arduino. The graph brightness is handled by the SAA1064, while the LCD's backlight is being dimmed directly by the Arduino via a transistor and PWM signal.

  • I2C communication between an ArduIMU and Lego NXT

    An ArduIMU from DIYdrones runs the AHRS code and outputs euler angles for pitch and roll to the NXT over an I2C bus. The NXT is the master and the ArduIMU is the slave. The floating point values for pitch and roll are broken down and sent as a package of bytes. A LabVIEW code on the NXT recombines the package of bytes.

More Information here - www.autosportlabs.org This is a prototype I made to test several technologies I am developing for my other Project (a 1976 Valiant Hemi Charger). Most of the details are in the Video. Arduino (AdaFruit Boarduino), I2C Bus powering the OLED Display and Tayloredge Smart-Nixie Sockets running In-1(4) Nixie Tubes, In-13 Nixie Bargraph, Megajolt Distributorless Ignition Controller controlling the ignition timing and feeding the RPM (and other data) to the controller. More Details, Source code and Construction Tips (but no drawn circuit diagrams yet) are available if you contact me on the MegaJolt (www.autosportlabs.org) Forums. No, I won't build one for you (unless you are prepared to pay consulting engineer hourly rates), but I will describe and help you build your own. Yes, I know the Gemini is hardly an impressive Street Machine, but its my daily driver parts-getter that I'm testing this stuff on while I build my Triple-Webered Hemi Charger where the final version is intended for. :) Enjoy the glowing plasma Tacho !

Man kann zwischen Rock/Pop, Trance/Techno, Ultrabassboost und Bypass wählen sowie die Lautstärke regulieren. Ein TDA8444 dient als Anlogwandler für Lautstärke, Bass und Höhen sowie auch als LED-Treiber für Checkanzeigen der Klangfarbe. Die Lautstärke wird im internen EEPROM des AVRs abgelegt und bleibt auch bei Ausfall der Betriebsspannung erhalten. Der Quellcode wurde nun nochmals komplett überarbeitet und verbessert: electronicfox.el.funpic.de Da findet man den neuen Quellcode, HEX-File, INC-Datei und komplett.pdf.

  • Dare to Dream Different Contest - Brickstick

    I would create an application that allows children of all ages to build sophisticated Lego robots which are controlled by a wireless controller joystick without requiring a PC for programming. A child would use the touch screen to write a declarative program that defines how inputs on the wireless controller drive outputs on the robot. For example, a program could define that the vertical value on the left joystick is scaled and applied to the power setting on the left wheel. It could also define that a click on the left shoulder button steps the position of a servo through a series of predefined values or poses . The application would use the I2C bus to communicate with Lego Mindstorms hardware 3rd party devices including - Lego motors, servos, sensors, and the wireless controller. It may also utilize devices on the prototype board including the accelerometer, buttons additional GIO points. The key invention would be the creation of an intuitive touch driven interface to build and execute the program, and monitor the IO. My initial designs are inspired by the touch interfaces on the Squeezebox, Touch Microsoft Surface. These utilize careful layout, color c

  • pressure sensor read out via AVR

    here is a little demonstration how sensitive the SDP610 (Sensirion) differential pressure sensor is. It can be read out as a I2C slave device, the numbers on the display are hi byte, low byte and checksum byte of the measurement. One tick corresponds to 1/60 Pa ( the atmospheric pressure is rougly 100.000 Pa, just for the sake of all those zeroes and so that you get the idea). You can see almost everything including the air movements when I move my hand :-) remember, it's a differential pressure sensor and the other port is right beneath the connected input (white silicone tube). I forgot to show the start-up sequence. I perform some tests on the I2C bus and the device, followed by a soft reset. Feel free to ask me if you have trouble interfacing this device. And now for some good news: you can get a sample from Senrision, entirely free of charge :-)

  • Brickstick - Lego NXT Programing without a PC

    This is my video submission for the Microsoft Dare to Dream Different contest (dreamdifferentcontest.com). The contest required entrants to build an embedded application using the new .Net Micro framework which allows C# programming on a resource constrained platform. The entry needed to use a prototyping board with touch screen provided Microsoft. My entry was a touchscreen driven programming & execution environment called Brickstick that allows Lego I\O to be connected to the prototyping board and programed and run controlled without the use of a PC. All programming and execution is done through the touch screen. This makes it easy to build remote controlled robot with sophisticated features, without the complexity of a complex programming environment. My entry used a number of complex I types utilising the I2C bus such as the NXTCam, NXTServo and PFMate, all designed and built by Mindsensors. Its also used some other interesting I/O types such as the BlinkM and an LED array. Unfortunately the sound quality is not very good as I needed to use a Bluetooth wireless headset to record the sound when my PC card failed. Towards the end of the video you can see a robot I built called the Mighty Digger which shows off Brickstick in its best light. Many thanks to Mindsensors for their support in getting the sensors up and running on this non-conventional platform.
