I own several Arduino's and shields. * 2 [[http://arduino.cc/en/Main/ArduinoBoardUno|Arduino Uno]] * 1 [[http://arduino.cc/en/Main/ArduinoEthernetShield|Arduino Ethernet Shield]] * 1 [[http://www.dfrobot.com/index.php?route=product/product&product_id=52|DF Robot Ethernet Shield]] * 1 [[http://www.sparkfun.com/products/9219|Arduino Pro 328]] 5v/16MHz * 2 [[http://www.sparkfun.com/products/9218|Arduino Pro Mini 328]] 5v/16MHz * 1 [[http://www.dfrobot.com/index.php?route=product/product&filter_name=proto&product_id=55|DF Robot prototyping shield]] * 1 [[http://www.dfrobot.com/index.php?route=product/product&filter_name=lcd&product_id=51|DF Robot LCD Shield]] I own 2009 (Older Version) * 1 [[http://www.seeedstudio.com/depot/solar-charger-shield-v2-p-914.html?cPath=132_134|Seeed Solar Charger shield]] [[http://www.seeedstudio.com/wiki/index.php?title=Solar_Charger_Shield_v2.0b|Wiki page]] * 1 [[http://arduino.cc/en/Main/MiniUSB|Arduino Mini USB Adapter]] The revised one. Used [[http://sureskumar.wordpress.com/2011/01/17/connecting-arduino-pro-mini-328-with-arduino-serial-usb-board/|this layout]] to connect The Pro Mini 328 to the Mini USB Adapter. But apparently this doesn't work because reset isn't pulled 'hard' enough or something. No biggie: just connected pin 3 from the Serial USB board to the 'next' pin on the 6 pin header. So eventually I connected 5 pins of the 6 and now it's working like a charm on the Pro 328 and the Pro mini 328. Me happy! Link I used for my LikeJar [[http://itp.nyu.edu/physcomp/Tutorials/ArduinoBreadboard|Arduino on a breadboard]]. The switch is to disconnect the pin3 from the FTDI chip, to use the Arduino Pro Mini as a AVR programmer using the Arduino-ISP sketch.\\ {{:usb_serial_mod.jpg?500|The way it looks now.}} -- Not really Arduino but handy (for me), links to other stuff in my component box. * 4 [[http://www.sparkfun.com/products/315|H-Bridge Motor Driver 1A]], [[http://www.sparkfun.com/datasheets/IC/SN754410.pdf|Datasheet]], [[http://itp.nyu.edu/physcomp/Labs/DCMotorControl|Usage example]] * 3 [[http://www.sparkfun.com/products/9453|Line Sensor Breakout - Analog QRE1113]] * 1 [[http://www.sparkfun.com/products/692|Triple Axis Accelerometer Breakout ADXL330]] * 1 [[http://www.dfrobot.com/index.php?route=product/product&filter_name=gp2d12&product_id=113|Sharp GP2D12 IR Range sensor]] * 1 [[http://iprototype.nl/products/arduino/modules-adapters/rf-receiver-434mhz|Rf receiver]] ([[http://winavr.scienceprog.com/example-avr-projects/running-tx433-and-rx433-rf-modules-with-avr-microcontrollers.html|Usage example]]. * 2 [[http://iprototype.nl/products/arduino/modules-adapters/rf-transmitter-434mhz|RF transmitter]] * 1 Kingbright 3 digit 7 segment display.
