How to program Attiny85






Matrials
-Arduino
-Attiny85
-Wires
-Arduino IDE software


Attiny is a micro processor and it can do what normal Arduino can do, but much smaller. Attiny has eight pins, reset, Analogput 1 ~3(also can be used as an digital input). 2 more Io that can be used to send PWM signal.






To program Attiny you will need an older version of the Arduino IDE (1.0.5), and then you have to download the Attiny library from this link(https://github.com/damellis/attiny/archive/ide-1.0.x.zip) add the unzipped library to the hardware folder in the main Arduino folder. After you have done that you will see bunch of board lists that means that you have completed with the libraries. Now you will connect your Arduino to your computer and Go to files and add ArduinoISP from the example. You don't want to change any thing on the ISP file just upload it to your Arduino.

Now we can connect our Attiny to Arduino.

This is how the Arduino and the Attiny should be connected.



Pin 13 -> io 2
Pin 12 -> io 1
Pin 11 -> io 0
Pin 10 -> Reset
5V -> Vcc
GND -> Ground


Chooses board to Attiny85 8MHz and change the programmer to "Arduino as ISP"
Now you can upload Arduino codes on to Attiny.

Here is a quick Demo video

How to make a very simple crystal radio

Image
Crystal Radio. I have created a crystal radio just using one germanium diode and a magnet wire and will also need a crystal earpiece or you can us audio amplifier. (I use germanium diode because this diode has low voltage rating then other diodes) When my radio receive the signal from the air it is alternating current, but our diode rectifies the AC signal and only allow the positive signal pass through. Finally the signal goes through the ear piece or the amplifier  so that the human ear can hear. First step to create this is to wind a coil on a 10cm box and you will connect the end of the coil to the antenna and germanium diode. After that you will connect your crystal earpiece(amplifier) to the other side of the diode and connect the other side of the ear piece to the other side of the coil and to the ground(you can use your body as ground).

Broken Jump rope counter

Image
I had a jump rope with a counter on it. One day it didn't work. So I took the jump rope apart and then negative side was not connected to PCB so I connected. I also added a cheating button. This process took a lot of time for me beacuse the wires would not fit in. I noticed that the LCD display isn't connected by any wires. I think the pink thing has like little wires in them so if u attach it sends data. Unfortunately, I accidently took off the pink stuff from the display. So I couldn't fix the jump rope.
