Use a ATTiny85 (can be ATTiny45, ATTiny44) to make an Arduino just for US3.00 and name it as Tiny Arduino.

Tiny Arduino have only eight pins as shown in figure above, Pin4 is ground (Gnd), Pin8 is 5V (Vcc), Pin1 is Reset, Pin2 and Pin3 originally used to connecting the Crystal. In order to utilize all the IO, the internal oscillator (RC Oscillator) is used to replace the external clock which require a crystal. Therefore the Tiny Arduino is now come with five IO. Below shows the Arduino IO functions.

1. There are five IO, each IO can be Input or Output
2. Among the five IO, two of the IO can perform as PWM
3. Among the five IO, three of the IO can perform as Analog Input

I2C may require to extend the features of Tiny Arduino.

Step 1: Materials

1 x 5V power supply power supply
1 x Breadboard (Project board)
1 x ATtiny85 (This is our Tiny Arduino)
1 x Arduino Duemilanove (use to upload Sketch to ATTiny85)
1 x 10 uF capacitor  (prevent Arduino duemilanove from automatically reset)
5 x LED
5 x Resistors
and some Wires
<p>have you used with a external crystal? if so do you need to change the board files to use a external crystal? there is no option by default for a external crystal</p>
<p>that I can do to convert 2 PWM inputs (rc servo) to 5Vdc analog?</p>
The photo in Step 9 gave me an idea to create a standalone Arduino ISP in a prototype shield to mount over this one another shield, with the socket and the components to flash the Bootloader and also flash a sketch in a ATMEGA328. <br/>I have been busy a couple of weeks!<br/>Thank you!
Could you also control a servo/lcd with the attiny?
Servo Tester based on ATTiny85 <br>https://trandi.wordpress.com/2013/06/18/servotester/
This may help you for servo. <br> <br>http://www.cunningturtle.com/attiny4585-servo-library/
I am looking to do something like this for my servo need smching if I were to follow the link on cunningturtle.com would I just add that code instead of the code that was listed in this instructable onto sketch? Thanks for you help.
You have to follow my procedures to burn the code (servo sketch provided by cunningturtle.com) to the ATTiny45/85

I didn't test with servo, anyway it support LCD. See the instructable by baharini. <br> <br>http://www.instructables.com/id/ATTiny4585-LCD-display-control-with-a-shift-regis/?ALLSTEPS
Nice post. Thanks. <br>On your &quot;5 channel running light circuit&quot;, it's a good idea to tie the reset (pin 1) to 5V. If you leave it floating, you may find the AtTtiny resets itself randomly. If you use a resistor with a high enough value (10k) for this &quot;pull-up&quot;, you can still program it with your ISP.
Yes, you are correct.
Here is some extra help for those using the Mega ADk or Mega 2560 instead of the Uno or Due.<br> <br> Check it out:<br> <a href="https://www.youtube.com/watch?v=DebJ1s5I3QM" rel="nofollow">https://www.youtube.com/watch?v=DebJ1s5I3QM</a>
You can actually get the chip on the uno, the atmega 328, for cheaper then you can get the ATtiny. Amazon currently sells the atmega 328 for 1$ a piece.
Are you sure? <br>The cheapest ATMega328 that I can get from Element14 (Farnell Malaysia) is RM12.99 (about US 4.16)
You can make the code smaller with a for loop.
Tried this one today. But i get an error: &quot;avrdude: usbdev_open(): did not find any USB device &quot;usb&quot;&quot;. What does that mean?
Are you using Arduino duemilanove as your AVRISP? Make sure you can upload AVRISP sketch (from Arduino software example) to your Arduino duemilanove first.
thanks for the info, I keep meaning to starting messing around with the ATtiny, maybe this will motivate me to really do it!
