How to use Atmel ATtiny85 with Arduino || Arduino tutorial

In this video I'm demonstrating how to program and use Atmel ATtiny85 with Arduino code. If you have a small Arduino project and need only few input and output pins, you can substitute the 28-pin Atmega8/168/328 microcontroller with the small, 8-pin ATtiny85 chip. You'll save some space, simplify your project and decrease power consumption.
The ATtiny85 microcontroller offers digital, analog and Pulse Width Modulation pins.
By default Arduino IDE doesn't support the ATtiny chips, but High-Low Tech Group at MIT Media Lab created their own libraries and shared them publicly. You can download them free of charge here:

This tutorial is based on High-Low Tech Group's explanations found on their website:

Cool I never knew you can do that. Makes my life making small circuits much easier.

[Miata]

Just now saw this video. So Darned Cool! Working on a project for a tiny embedded system w/ low skills and no budget. This is the perfect answer! Thanks!

[northshorepx]

Thank you so much! I've just got into Arduino and in 6 minutes you've opened my eyes/given me a massive paradigm shift in understanding why this is such a powerful and versatile system. Could you tell us some more about what you've learned in real world terms of the power and battery requirements for this small microcontroller please? Ps your dog is very sweet!

[frankroni]

Nice clear explanations. I have several Arduino projects that I hope to transfer to ATTiny's.

[DevineIshaq]

This was incredible set of instruction. Thanks

I'm using Attiny84A, how do you do the analogRead on it? Mine doesn't seem to work.

[roberthenry]

newb here...dumb question time, are the AT, s re-writable?...and if they are how do you burn it forever, ....sorry, big time newby, but dabbles with mostly audio electronics ....and would like to build/burn dedicated projects....cheers man. rob.

Question....
There are 8 pins on an ATTiny85. Vcc, Gnd and Reset, does that leave the other 5 pins for I/O?
Thanks

[MagiKnightOne]

Impressive and simple tutorial.

Thank you.

[RahulSingh-myvx]

sir when i program it i get avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check." please help me about it

[jenpau]

arduino 1.8.3 didnt work i cant see the attiny in board, can you help us?? please thank you

[thevivekmathema]

PLEASE HELP!!! [URGENT!!!]
Can I use 25V 2.2 uF electrolytic capacitor instead of 50V 10uF capacitor? i don't have the 10 uF cap and I need to complete the project urgently. i worry that I will destroy the Chips!.. Thank you

[malagiyawanna]

can anyone help me to do this. what i want is when contact get open ( assume a reed switch) then LED get blink 10 S and off.I want to use ATtiny85. Thank you.

[lshi]

could i also use a 100µf compacitor because i didnt have a 10µf here?

[pepijn_m]

nice video, can you explain how to use atmel studio with the attiny85?

[fmoreno]

excellent video, I was wondering...can I reuse the attiny85? 

[gustavosilveira]

Hi, great video! But, how can I make a standalone? How I would use a battery? Thanks!

[volodymyrishchiv]

Is it also possible to program Atmel ATtiny15A using same technic?

[electrolove]

If we disconnect the ATtainy85 with arduino uno after programming, and give the power supply with out source, will it work as the program?

[InventionTherapy]

What is the best Arduino to start learning on?
