this project is an easy methode to program a arduino pro mini whit the uno.
the things you need for this project are:
- one of 2 pins
- one of 3 pins
- two of 6
Step 1: The Schematics
The schematics are verry easy, it is just connecting whit the pictures.
For connecting the female pinheaders look ad the PCB picture
For etching your own PCB there are PDF doc's avalible on the rigth size
Step 2: Prepare the UNO
For installing the UNO you have to remove the ATmega chip. The moste easy way to do this is with a simple tool called a IC puller or you could do it with a tweezer.or a verry smal flat screwdriver
Whe you place the IC back it better if you don't push it al the way down, so it wil be easyer to remove the next time
Step 3: Preparing the IDE
In the arduino IDE you had to select the arduino pro mini whit the exact specs of the pro mini (Frequentie and the voltage)
When you select the UNO, the programmer doesn't work
Step 4: Adding the Pro Mini
Now you had to put the shield ontop of the prepared UNO.
When you have don it than you had to pin the mini in to the shield.The moste inportant thing is that you select the good "port" for it and that the oriantation is good. The mini TXO pin had to be on the far left edge of the shield
Now you can program your mini pro just like a normal UNO
