Fun with micro-controllers!

Fun with micro-controllers! by Steven and Sarah.
Exploring micro-controllers with the Arduino NG development system. Seen here running in standalone mode with a 9v battery. Arduino makes embedded programming fun and easy by bringing together a clean and simple hardware and software development environment.

Here, I'm messing with reading analog input from a 10k potentiometer and PWM (pulse width modulation) of leds to produce variable brightness.

Link to my RFID tagged blog entries, with video of the setup above in action: stevenandsarah.com/category/rfid/
www.arduino.cc/ - "Arduino is an open-source physical computing platform based on a simple i/o board, and a development environment for writing Arduino software. The Arduino programming language is an implementation of Wiring, itself built on Processing."

cool... I just got mine today, I'm looking to do the same (among other things). I need to PWM control 7 sets of LEDs, not sure if the ATMEGA8 can do that. I was using a Basic STAMP to do it before, but I'm trying to get this less expensive guy to do it.

are you using one of their programs or your own?

just got my arduino today, and im psyched!

Hey, We're Make famous!!! That picture is part of my preparation for setting up an RFID doorlock system. It's based on the free RFID Toys chapter at www.rfidtoys.net/bonus.asp but I'll be using an arduino/atmega8 setup and Limor's/Ladyada's Minty Boost 5v power system to run it.

I'll post more pics to the make group as I go about getting my RFID implant, and start building the board and installing. I'll also include a link in the pics to my blog where I'll include schematics and arduino code.

christolles,

Just running a modified version of this in the picture:

Important note they seem to forget on the Arduino website: Arduino only "accepts for download" a new program in the first few seconds of reset. Meaning, you need to press the small reset button on the board, then immediately click the download button on the software. Call me silly, but it took me a while to figure that out.

jmillerid,

Just see this arduino url for information on a 99 cent add-on chip to control 8 leds with PWM. You can chain them together to control dozens, it appears:
