Can we use Arduino Uno instead of Arduino Pro Mini?

The first glaring hardware difference is the voltage that the Mini operates at: 3.3V. Unlike the Arduino Uno, which has both a 5V and 3.3V regulator on board, the Mini only has one regulator. The Pro Mini 3.3V runs at 8MHz, half the speed of an Arduino Uno.

What does Avrdude mean in Arduino?

The tool avrdude is used to upload sketches to the Arduino boards which use microcontrollers of the AVR architecture. When uploading code to your board in the IDE, avrdude may give an error. avrdude: ser_open(): can’t open device “portName”: the system cannot find the file specified.

Arduino PRO MINI – How to upload code

  1. There is a voltage regulator on board so it can accept voltage up to 12VDC.
  2. First let us upload code using the 6 pin version .
  3. Plug in the USB board to PC & open the Device Manager .
  4. Open the Arduino IDE , feed in the COM port allotted.
  5. From Examples open the BL;INK sketch.

Why Arduino is not working?

First make sure your board is on (the green LED is on) and connected to the computer. The Arduino Uno and Mega 2560 may have trouble connecting to a Mac through a USB hub. If nothing appears in your “Tools > Serial Port” menu, try plugging the board directly to your computer and restarting the Arduino IDE.

What does not in sync mean in Arduino?

This error is what happens when your computer isn’t communicating with the Arduino. It has nothing to do with whether your code is right or wrong. The most common cause of this error (IMO) used to be people choosing the Duemilanove 128 when they had the newer Duemilanove 328.

What is stk500_getsync error avrdude?

Many new people find this error avrdude: stk500_getsync (): not in sync: resp=0x00 while uploading program to board. Before we start to conclude the error first know how arduino works.

What are the common errors in Arduino Uno?

Error Reason 9: External Crystal is missing or faulty. Check that Most of the Arduino boards use 16MHz or 8MHz crystal, If you are trying with fresh chip, this is common mistake. Use 16MHz crystal for ATmega328p with Arduino UNO boot-loader. These are the most common mistakes that cause error avrdude: stk500_getsync (): not in sync: resp=0x00.
