projects are very popular but also big and expensive. There are many times that we don’t need so many input or output pins. As a matter of fact, most projects could be accomplished with only 2 or 3 inputs and outputs. Besides the size, using one Arduino board for each small project can be costly.
So the solution is given (again) by Atmel with the ATtiny microcontrollers
. Especially the ATtiny85
chip, which has 8 Kb flash memory, 6 input/output pins, low power supply at 1.8-5.5V, small 8-pin packaging and costs only 2-3$.
It is very easy to program the ATtiny85 using our own Arduino board based on the tutorial Arduino-based ATtiny programming
published by MIT’s High-Low Tech
In this instructable
I will try to guide you step by step, through the whole procedure of constructing a small board – shield for the Arduino, so that the programming can be made easily and fast. This is what I named the ATtinyShield
. For more Arduino and ATtiny85 projects, check my blog: http://attiny85.blogspot.com If anyone needs the PCB and/or the Shield premade check here:
