Programming Arduino mini pro using USB to TTL converter

Here in this post i'm going to tell you how to program your arduino mini pro using a USB to TTL converter.

Requires:

1.USB to TTL converter( I used D-SUN)
2.Arduino mini pro
3.Connecting wires

Connections  USB-to-TTL  to Arduino Mini Pro:

1. USB-to-TTL: TX (Green) -> Arduino Mini Pro RX
2. USB-to-TTL: RX (Violet) -> Arduino Mini Pro TX
3. USB-to-TTL: GND (Yellow) -> Arduino Mini Pro GND
4. USB-to-TTL: +3.3Vcc (Red) -> Arduino Mini Pro VCC

1.Now open your program in Arduino IDE 

2.Select your arduino board (here it is arduino pro min)

3.Select your processor (here it is ATmega328(3.3v,8MHZ)

4.Click on Upload sketch (green right arrow)

5.when  you see "compiling sketch " on status bar press and hold pro mini reset button

6.As soon as you see "Uploading" on status bar release pro mini reset button

7.If your timing is correct  you will see "Done Uploading" .  :-)
