Introduction: Ardiuno Pro Mini Programer Tool

Picture of Ardiuno Pro Mini Programer Tool

this project is an easy methode to program a arduino pro mini whit the uno.

the things you need for this project are:

  • Malepinheaders
    • one of 2 pins
    • one of 3 pins
  • Femalepinheaders
    • two of 6
  • protoboard
  • wire

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

Nice shield, but you need to reverse the TX-RX lines. Thanks

Basv29 made it! (author)acheide2017-01-02

You say, that the good way is like the picture in this comment. But I have looked it up on google and every one say to do it lik i have done and it hase also never failed with programming.

Well, if it works Basv29 apparently is right. However, purely from a theoretic point of view, I would think acheide is right.

In
your setup, Rx is connected to Tx and Tx to Rx. usually that is how it
should be but in this case, you are using the usb interface. the Tx pin
of that one goes to the Rx pin and the Rx pin to the Tx pin of the
328... in your setup the mini however "replaces" the atmega and in order
to connect the Tx of the mini to the Rx of the usb interface, it needs
to be connected to the Tx pin of the Atmega

Nice DIY programming shield. I always like making my own shields instead of buying them. It helps me to better understand how they work.
