I had finished sewing an Atmel ATtiny45 into a paper breadboard when I realized that I hadn’t programed the micro controller! Luckily I was able to attach alligator clips to the ATtiny45 pins and program the chip with a fade program via an Arduino Uno.    

  Traveling is never dull as a I wake at dawn to program ATtiny45 microcontrollers for next weeks hackers at Ljudmila PIF Camp in Trenta, Slovenia.   Luckily I have my own tutorial on using Arduino as ISP and fresh coffee!    

  The workbench remains littered with ATtiny45’s, Arduino, LEDs, and breadboards.    

  How to set up a breadboard circuit for ATtiny45 to blink five LEDs in sequence.     BREADBOARD CONNECTIONS ATtiny Pin 0 to LED positive (signal, white) ATtiny VCC (+) to power positive (+, red) ATtiny GND (-) to power negative (-, black) LED negative to resistor (breadboard connection) Resistor to negative power (-, black) repeat for Pin 1, […]

How to set up a breadboard circuit for ATtiny45 to blink one LED. BREADBOARD CONNECTIONS Connect Power to ATtiny Power positive to ATtiny VCC (+, red) Power negative to ATtiny GND (-, black) Connect LED LED positive to ATtiny Pin 0 (signal, white) LED negative to resistor Resistor to negative power (-, black)   CODE Upload the following code to […]

  When working with Arduino to program ATtinys I use this standard breadboard set up. The right half I use to program and the left side I use to test.   This system allows me to upload the boot loader and code and then quickly test the microcontroller for blink.

I’ve been working on the interactive eTextile flowers that I will present at the Denver Art Museum Untitled event Friday 26 April. Inside this felted stamen I inserted a Maxbotix ultrasonic range finder   This sensor will feed analog information to an ATtiny45.  If the range is within two feet then the 10mm red LEDs will illuminate. If you are […]
