ATtiny programmer using Arduino ISP

ATtiny programmer using Arduino ISP | robots | Scoop.it

For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC)  and low power consumption.

There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude).

I'd like to share how I program ATtiny85 with JeonLab mini 1.3. The idea has been adapted fromHigh-Low Tech Group and provideyourown.com. One missing note from High-Low Tech Group is that you need to add a 110-120 ohm resistor between VCC and Reset pins of JeonLab mini (or Arduino) to prevent Auto reset on serial connection as explained in here and here.

Using Shift Registers Tutorial

Using Shift Registers Tutorial | robots | Scoop.it
Shift Registers can greatly expand the I/O capability of your microcontroller. This is the best tutorial I have even seen. Kevin has a great teaching voice / method that makes things clear.
