Main board

All of our electronic boards are connected to Main Board.

This board includes:

Atmega2560 Microcontroller

LM2596 Regulator  

USB to Serial converter


LM2596 Regulator provides the input voltage of our Microcontroller , our battery is 12 Volts but our microcontroller needs 5 Volts.

LM2596 is a switching regulator, you may ask yourself why did we used a switching regulator, because linear regulators heat up and for decreasing its temperature you should use a fan , cooling pad , etc. And because they occupy a lots of space we used a switching regulator , they don't heat up to much so it doesn't need a cooler. (regulator's have two types switching and linear) 

If we use the switching regulator by it own our microcontroller will destroy so we use a electronic circuit to make it like a linear regulator.


                      Switching Regulator                             Linear Regulator


We used ATmega2560 microcontroller it has 256KB flash memory ,8KB ram , 4KB EEPROM memory , 16M crystal and it has 100 pins that 86 of them is programmable. We had a lots of other options but this one was our best option because it has everything that we needed and it has a good price.

Sensor Board

This board is located on the bottom of the robot and has the task of following the line. Sensor board includes: IR Sensor's Apds 9960's Multiplexer's Ams1117 We used 34 IR sensor's to follow the line, It has a receiver and transmitter , infrared waves are from 300GHZ to 430 GHZ and the length of these waves are from 1mm to 740nm. We could use a lots of things to detect red and green color but we choose APDS9960 Because it was more accurate and cheaper. We used two of them in the robot. Also we used multiplexer's because we didn't have enough pin's, 4051 and 4052 multiplexer's. We used Ams1117 because the input voltage of our color sensor (APDS9960) is 3.3Volts and our battery's are 12Volts so we need to reduce the voltage, you may ask yourself why didn't we use Resistor's to decrease the voltage , because it will be destroyed and we should use a lots of them and it will occupy a lots of space and the main reason is regulators make our voltage...

LCD Board

We used this board to connect our LCD Display (TFT ST7735R) to our robot, Also this board has a gyroscope (GY-25) and a buzzer. The gyroscope is because we need to know if we are on a ramp Our gyroscope (GY-25) can communicate two different type of communication protocol's I2C and USART , we used USART communicating protocol, the accuracy of this module is up to  ± 180 degrees.

OpenMV

 We had a lots of options to use for detecting the color of Evacuation Points , like OpenMV Camera , APDS9960 , Pixy Camera , We used OpenMV h7 plus to detect the  color of the Evacuation Point in the Evacuation Zone. The OpenMV that we used has a 5 megapixel camera and supports several communication protocols including UART, I2C, WIFI, SPI , USB , Bluetooth , etc.  To receive information from this camera , we used a 5 pin connector , which includes: VCC , GND and three digital pins. This camera has three microcontrollers named STM32H753, IS42S32800G 6BLI and 25Q256JVEQ-1912.
