How-To: Shrinkify Your Arduino Projects

If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. In this video, Matt Richardson shows you how, based on a tutorial from MIT Media Lab's High-Low Tech Group. The best part is you can use the same Arduino code and development environment that you're already used to.

I find the last sentence about what the tinys will understand is a real let down. Reference From MIT high low tech site. The following Arduino commands should be supported: pinMode() digitalWrite() digitalRead() analogRead() analogWrite() shiftOut() pulseIn() millis() micros() delay() delayMicroseconds() SoftwareSerial (has been updated in Arduino 1.0)

Blink:21: error: 'delay' was not declared in this scope

Blink:22: error: 'LOW' was not declared in this scope

But why do you need it in the first place?

No you can see at 3:06 that when running only from battery he is not using a capcitor

[DemangoProductions .]

Why do you have to use the Capacitor?

[AndyGadget]

Shrinkify ?!?!

Looks more like you're smallerizing it to me !

I want an audrino now....

[Razuliann]

Dat smile!

[ttttkk2]

can I program a atmega16a-pu chip like that?

But Attiny45_85 library is looking for WProgram.h so that is why there is a mess.

Also while compiling, it is possible to have the following error:

avrdude: stk500_getsync(): not in sync: resp=0x00

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

To fix it, you will need to remove the 10uF cap before uploading the example ArduinoISP code.

And voila! Happy coding!

Okay for those of you who are having the following problem:

Blink:15: error: 'OUTPUT' was not declared in this scope

Blink:15: error: 'pinMode' was not declared in this scope

...

Here is a small tut. of how to fix it:

you need to download Arduino software version 0022.

Then follow the same tut. as shown in this video.

It will WORK!

The reason that 'OUTPUT' and other arguments are undeclared is because from Arduino update 1.0, they changed the core library WProgram.h to Arduino.h.
