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, […]

  Red LEDs are electron hogs. They will always be the first to glow and even prevent other LEDs from illuminating.     When designing your circuits be sure to isolate the red LEDs from other colors otherwise you’ll have a darkwad in the final design.   read more on LEDs at wikipedia

  I’ve been thinking the eTextile Lounge deserves a new photo, but I love this one so much!

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 multiple LEDs for the same project take a moment to determine how to indicate the polarity of the LED.     Before I begin a project I use paint, nail polish, beads, or bend the LEDs positive and negative leads into specific shapes.     This allows me to quickly and accurately add LEDs to the […]

  This is a force-sensitive resistor available from Adafruit for $7.00 USD.   Thru hole connections make this pressure sensor easy to adapt for eTextile use.     The sensor pad can be embedded into a textile or paper computing design.   You can also use conductive fabric and velostat to make your own pressure sensor. Just follow my video […]
