UNIVERSAL PERIPHERAL INTERFACE

8-BIT SLAVE MICROCONTROLLER

Testing out an ADXL335 accelerometer, and interfacing it to an AVR microcontroller. Read more here

This plastic part fits a single Arduino microcontroller board to protect its bottom from short circuits. The Arduino clips in to the plastic shell by a small overhang on the top of the walls. The smooth curves and regular pattern of plastic lines created by melting a thin filament of material and squirting it on top of the previous layer makes for a design reminscent of a geological formation.

The Basic I/O Shield is designed to provide a range of input/output devices suitable for beginners learning about microcontrollers and various types of I/O devices, or for use by more advanced user to provide inputs or outputs for their own projects.

 

The Basic I/O Shield provides simple digital input devices such as switches and buttons, and digital output devices such as discrete LEDs and high current open FET drivers. It provides more advanced devices such as an I2C EEPROM, an I2C temperature sensor, and organic LED graphic display. A potentiometer is also provided for use as an analog input device.

A spare part for a Nokia 1202 mobile phone, which is a handy 96x68 pixel display for microcontrollers. The interface is 9-bit SPI at 3.3V levels and uses an STE2007 chip, bonded directly to the glass. I've got it wired up to the MSP430 LaunchPad board, partly because that board is 3.3V and partly because there's a handy bit of example code, here: dangerousprototypes.com/forum/viewtopic.php?f=19&t=3486

Pixel VGA, version 1 (Floor Cluster) - Garnet Hertz

 

Two dozen old computer monitors occupy the center of a gallery floor in a cluster facing the wall. Each screen is controlled with custom electronics to create pulsating and strobing patterns, casting a colored wash across the darkened gallery.

 

Dimensions: Variable (approx 3m x 3m). VGA monitors, custom electronics. 2011.

I designed and built a passive infrared trigger for my Canon EOS 5D camera (will work with any camera with a remote shutter release socket) to take pictures when something (an animal) sets off the PIR sensor. This will allow me to set the camera up to automatically capture anythng that moves in front of the sensor. I used a microcontroller to control the camera wake up and shutter release relays. This gives me the ability to control the frequency and number of shots. For the prototype I trigger the wake up relay for 300ms then the shutter release relay for 300ms followed by a 300ms pause before checking the input again to see if there is still movement in front of the PIR sensor. I also put a long delay (1 second) after 5 continuous shots. Depending on results I may replace this long delay with a wait until the PIR is no longer being triggered to prevent too many pictures of one event if the animal stays in range of the PIR sensor for a while. The cool thing is that the camera can go into sleep mode allowing the battery to last for days as the circuit wakes the camera up when movement is detected.

Microchip Technology's MCP6051/2/4 (MCP605X), MCP6061/2/4 (MCP606X) and MCP6071/2/4 (MCP607X) op amps feature offset voltages of just 150 microvolts and are well suited for applications requiring low power consumption, low-voltage operation and high precision, such as those in the industrial, medical, consumer and other markets

The class provides a hands-on opportunity to build and program a variety of interactive circuits.

Arduino controllers are very powerful, but it's easy to get started programming them-especially with our kits.

I just received these 2x16 LCDs (and one 2x40) white on blue with LED backlight. This is a setup for using it in 4bit mode with an I2C IO expander. (Excuse the bad pict, blue LCDs are a pain to shoot)
