How to Program Attiny Using Arduino Uno

I just wanted to make a small arduino for my few projects because buying a arduino for every project will be too expensive for a 15 yrs  old guy !!!!!

Step 1: Things You Need

arduino IDE
attiny files on ur arduino IDE
You can download the files given below and move the files in hardware
1- arduino uno
1- attiny 45 or 85
1- breadboard
few jumper wires
1- 10 uf capacitor

Optional (if you u want it permanent )
1- perfboard
1- 1 led any colour that u like
1- 220 ohms resistor
and some pin headers

Step 2: Lets Get Starded

Open the arduino IDE
and open the arduino isp sketch from the examples and upload it on your uno Note(don't connect anything to  arduino while uploading the isp sketch).

Step 3: Step 3:- Connecting It With Attiny

Unplug ur uno from the computer and connect it with attiny as shown in the picture below after wiring it then connect the 10uf capacitor the + wire to the reset pin and the - wire to gnd pin after wiring it connect it with usb
Here are the pinout
attiny pin 1- arduino pin 10
attiny pin 5- arduino pin 11
attiny pin 6- arduino pin 12
attiny pin 7- arduino pin 13
attiny pin 4- gnd
attiny pin 8- 5v
TA ADA!!!!!!!! now u can program attiny

UPDATE: Here is the schematic of the attiny programmer with the led and capacitor , there is also a pcb view of the shield

Step 4: Making the Circuit Permanent

I made the circuit because i need to program more attiny's so it would be consume time for making the circuit again and again
here are some photos of the shield I hav also added a led in the shield and also check the video

Another question:
The ATtiny85 clock is chosen between 8MHz or 1MHz (Arduino Uno's is 16MHz) so let's say I will use ATtiny85 with the 8MHz clock to make a Led Matrix Clock; This clock, however, will not work at half the clock speed, and the Arduino Uno works at 16MHz, thus delaying the clock time? Thanks

Thanks for the tutorial.
To load the sketch, it is not necessary to write the bootloader in Attiny?

[Sauspin]

I think to program the sketches is necessary to burn the bootloader first.

[Jamebonds1]

No. Don't bootload ATtiny. It will damages your mircocontroller.

first i am impressed with you because you r just a 15yr teen...i m new to micro controllers though i studied during my college time..from few days i am looking for some info on net to make a pwm for a cheap..reliable solar charger..but i was so confused with various type of mc..as they needed first bootloader and then prog..aftrr reading your inst..i feel i got my answer..buy one uno and attiny chips for making pwm.s...great..i am glsd for u

[Jamebonds1]

I'm not 15 years old at that time haha. It is 24 years old at that time.

[Pranavthegreat]

actually no because the arduino doesn't have a bootload for attiny and as you are going use arduino as isp in the programmers option you don't need to bootload it

I was able to program an ATTiny 85! Thank you.

[AshokB25]

Hello. Can you please help me to program attiny102 using arduino. Thanks.

[LukášM33]

very thanks!

[majdia1]

Thanks for the diy. I saw some boards shield made with a reset switch button, could you tell why and for what it is used??

[Pranavthegreat]

To reset the code on your attiny

[arduinomaster]

purchase a shield to save frustration for only 8 bucks

Hi, if i need two digital outputs and four analog I/Os, can ATTINY24 does the job? Do I follow the same instruction as Attiny 45?

[Pranavthegreat]

No you can't as the attiny has only 3 analog also u can follow the same procedure for attiny 24 and even 13

Thx for the post... I am messing around with electronics and Arduino for years but never programmed an Attiny before... I had some Attiny45 lying around and wanted to peogram it using your shield... Made the shield according to the scheme and pics... downloaded the Tiny.zip and extracted to Arduino/hardware folder... Uploaded ArduinoISP and plugged the shield while not connected to USB... Later plugged the shielded arduino to usb and opened Blink example, selected Attiny45@8Mhz from board list and tried to upload sketch with no luck... It says:

avrdude: usbdev_open(): did not find any USB device "usb"

Tried the same on my other WinXP pc with a different response something like:

avrdude: attiny45 not present

Any ideas why? double checked my connections...

[Pranavthegreat]

if the arduino isp was uploaded perfectly then i suppose you should not face any problem and for the error i recommend you to search it on forums because i have never experienced this error before.

Nice tutorial! If you want to know how to do this with an Arduino Mega, check out my blog at: http://jamestav.blogspot.com/2014/08/programming-attiny85-microchip-using.html

[Fanima Dekoi]

Thank You! I use this a LOT.

[Pranavthegreat]

your board looks better
