you can find here Forward Voltage Which is Important to calculate the Resistance that we need to put beside the LED ..

you can Find that the Maximum is 2.6 Volt and current 0.02 A ..

So We need to calculate the Resistance ..

5V - 2.6v = 2.4V

Then the Resistance will be 2.4/0.02

Which will be 120 ohm ..



also Take in Consideration the arrange of the Pins of the Bluetooth to can deliver power and read data right .. and take care of the Orientation you will use ..

Then I start Building on it .. and this is the result ..






Task 2
Here are the Files to Be fabricated on CNC ..
For Fabricationg I followed the same Steps in Electronics Production Week





But I didnt notice this while I was making it on Fab Modules .. That there are a short circuit .. and this Short circuit happened because of I had in the design a circle because of un finished trace that I didnt See that above my trace that makes fab modules see them as 1 Trace and Didnt figure out that they are 2 Traces ..

the other issue that I need to take in consideration next is to leave a little more space between traces as I wanted to make my PCbs Design Perfectly Design with the Smallest Size and Traces ..


As A Credit For My Instructor Hagag He Had a Great idea Like you will see at the picture that he removed all the lines and let just the ground .. and this what happen .. the machine removed the short circuit ..



This is the error



Task 3
Then This is How it looks like my Final Output PCB ..
This how it looks like with Component




Task 4
This is the code i used for the output circuit ... Which read the data coming from the the Input circuit and Test it with LEDs and Pass it To the FTDI to Send it to the Connected Computer .

Here the PCB have 4 LEDs ..

2 LEDs for x axis and y axis
1 LED for Push Button state
1 LED For the connection of the Bluetooth


A Important note about the code ..
I Transform the Analog Readings to Digital Because of the Noise ..

To Understand the Code Syntax and How I Wrote it .. You can Check my Embedded programming Assignment As I made There a full Illustrating for How to use Arduino and What is all Functions I used There ..

Task 5
This is The working Circuit With the live data

• Eagle Schematic
• Eagle Board
• Output Code
