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 , 1
