Introduction: Uploading Sketch to Arduino Pro Mini Using Arduino UNO

I have started my way with the arduino UNO, moving to pro mini I didn't buy the USB adapter but used the UNO board to upload my sketches.

Step 1: Removing the Atmel IC

Very cerfuly remove the Atmel IC from the Arduino UNO, the pins are very gentel so be very cerful.
I used a flat driver, twisting it gently from both sides to take it out slowly bit by bit.

Step 2: Connection

Connect UNO's pin 5v to mini's main VCC pin,
UNO's pin GND to mini's main GND,
UNO's pin RX to mini's RXI,
UNO's pin TX to mini's TX0,
UNO's RESET to mini's GRN

Step 3: Load Sketch

Load the sketch to the Arduino IDE, for the example I used the Blink sketch wich is also used for an Arduino first test

Step 4: Set Board

Set the IDE for using the pro mini board,

Tools => Board => Arduino Pro or Pro Mini (5V, 16Mhz) w/ Atmega 328

Step 5: Upload Sketch

Upload the sketch using the regular uploading button.

Step 6: Your Good to Go

You should recive the "Uploading Done" massage in the status bar and you are good to go, sketch uploaded.

Now go make something...

A slightly different configuration worked for me:

Pro Mini ----- Uno

DTR -------- Reset

VCC ------- 5V

GND -------GND

RX -------RX

TX------------TX

Thank you very much. it worked for me.

I realize this is old but I tried this method and it worked properly.

in arduino IDE tools->programmer->?? what we have to select.

Hello!

I have an Arduino mini pro (a replica version). It was working fine, and uploading code fine. I dont think i changed anything. However now i am having the following issue:

- COM port coming up

- upload error: stk500_getsync() error.

I have other Arduino pro mini's in same set up that are working just fine so i dont think it has anything to do with the computer (drivers ect..) or the FTDI port.. It must be to do with the board.

Do you have any ideas? Its possible its the bootloader but that seems like such a rare issue that I would like to try other solutions first!

Any help will be gratefully received! I have collected data for my final project using this sensor and i didnt get to calibrate the sensor!

Thanks in advance!

arduino pro mini has a factory problem..i tried many of them do not take code, not from USB converter like PL2303 or any other ..also not from another Arduino...probably this model has a fundemental problems..i do not advice anyone to buy or use arduino mini..it is just a big waste of time

Thanks, very helpful!

hai friends i am using arduino pro mini board .and i can connect the board to usb using the cable named as(TTL to USB converter PL2303) but it can't connect the board so i cannot able to send my program in this board what can i do.......?help me for this problem the error like avr

dude ...

Can you provide with more details ?
Your connections, the complete error massage, etc.

Yeah ! it's working ! Thank you very much for this !
