PROGRAMMING A PRO MINI

Unlike Arduino nano, pro mini cannot be programmed directly by plugging in a USB cable as it doesn't have a built-in USB to serial TTL converter. Therefore first we should connect an external USB to serial converter to the pro mini in order to program it. The first image shows how these connections are to be made.

Vcc - 5V

GND - GND

RXI - TXD

TXD - RXI

DTR - DTR



COMPLETE CIRCUIT DIAGRAM

The 2nd image shows the complete circuit diagram of this project.

D2 - INT MPU6050

D3 - I/O (MODE)

D5 - I/O (UNIT)

D6 - I/O (ZERO)

D7 - +(1) ENCODER

D8 - +(2) ENCODER

A0 - I/O SHARP IR

A1 - + Buzzer

A4 - SDA (OLED AND MPU6050)

A5 - SCL (OLED AND MPU6050)

GND - GND OF ALL MODULES AND SENSORS AND BOOST MODULE

VCC - + OF BOOST MODULE USB PORT

B+ - BATTERY +

B- - BATTERY -


The 3rd picture was taken while I was creating the code. This is a temporary setup which was made for testing the code, modules, and the circuit. It's optional for you guys to try.
