I came across a bunch of stepper motors and I have since been looking for a project to do with the kids. An old Telecran (French for Etch-a-Sketch) later, we are in business ! What I used for this project: – an Arduino Uno – 2 stepper motors – 2 easydrivers v44 (by www.sparkfun.com) –
Telecran (Etch a Sketch) + Arduino = Telecranduino ! using arduino Continue Reading
Instantaneous Voltage and current AC Voltage and current continually alternate, as the name suggests, if we draw a picture of the voltage and current waveform over time, it will look something like the image below (depending on what’s using power – the current waveform – blue in the diagram below – is what you get

Now with more LED. Arduino mega powered breathalyzer using the MQ-3 sensor. A relative gauge for judging how intoxicated you are. NOT TO BE USED AS MEANS OF BREATHALYZING NEVER DRINK AND DRIVE. This is more of a device to encourage one to drink more. The MQ-3 can’t achieve the accuracy to register exact

Analog sensors produce an analog (continuous) voltage that typically varies from 0 to 5 volts. They have three wires – ground, power, and signal (typically red, black, and white, respectively). Examples shown below include: Potentiometers Proximity Accelerometers Ribbon Bend Pressure Light Temperature Sound Multi-touch Touch Other Potentiometers Potentiometers typically measure rotation or linear travel, and

This is an audio spectrum VU meter using the LoL Shield for Arduino . The LoL Shield is a 14 x 9 LED matrix which fits onto the Arduino as a shield and is controlled through an efficient method known as Charlieplexing . It was designed by Jimmie P. Rodgers . This project uses a

his project is mainly based in this one from Glaciar Wanderer. I just liked his idea and worked it on my own. (I think this guy and me would be friends, as the projects he has in his photography category are things I’ve been wanting to do since I got my Arduino. I will not

The TROBOT is a miniature six-axis articulated robot, modeled after large industrial & assembly line robots. The prototype versions were developed to be interfaced with ABB’s Robot Studio software. Robot Studio was designed to program, simulate, and debug real industrial robots in an offline virtual environment. This project uses the power of ABB’s ‘Virtual Robot Controller’

Quickly testing a GPIO pin To set pin GPIO_PH1 as an output: sudo su (Enter your user password. Defaults to “ubuntu”) # See which pins are currently configured as GPIO, and what their state is. cat /sys/kernel/debug/gpio # Validate that the entry for the Tegra GPIO controller has a base value of 0. If not,

I saw these POV(Persistence of Vision) devices on other Instructables and thought I would like to make one and I have always wanted my own “APPLAUSE” sign. Next improvement will be to make it go on whenever I enter the room. 🙂 Maybe have it say, “And here’s Charlie !” But that is for another

NOTE: This instructable is now slightly old and a better machine has been made with lower cost parts and much better software that automatically allows you to “pair” new cards with new tracks as they are added to the iPod playlist. iPod playback track selection simply by putting RFID “bricks” on a table. – An
