Microcontrollers – ATtiny45’s

ATtiny45’s can be easily programed using your arduino. Just follow the tutorial at MIT Media’s High-Low Tech Lab. Data sheet found from Atmel.

I use these for classes and my own projects because they are:

  • inexpensive, 100 for $63 USD at digiKey
  • small and easy to modify
  • enough memory for basic programs, 4KB
  • works with eTextiles and paper computing

Time to get to work – I’ve 100 ATtiny45’s to program!
