    I have a question...If I have uploaded a code on an Arduino mini pro from my mac using a USB and FTDI, with data that prints to the serial port. Then next time I plug in the Arduino, select the correct port ect, can i just open the serial monitor and see the data being printed to the serial monitor? Or do i need to upload the code again? The reason I ask is because the code that was uploaded on the Arduino originally has not been saved, so I would like to use the sensor without uploading anything again. Plus i keep having issues with uploading so it would be good just to know that I dont have to upload again and again each time I connect the sensor to the computer! Thanks in advance!

  • Uploading sketch to Arduino Pro Mini using Arduino UNO

    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! Harriet
