Interface and application programming

Introduction

So for this week's assignment I decided to make an LCD which will be used as user interface for the final project also it will be used in the communication assignment as it will communicate to the sensor PCB and upon it it will reply to the user.

PCB Design

So I began designing the PCB, so I searched on how to connect an LCD to Atmega 328P .

Milling

So this was a simple square PCB

Soldering

It was a systematic procedure but I had to be carefull while soldering the buttons also Later on I discovered that I forgot connecting the AVCC and the AREF to VCC so I added jumpers.
