Salah's Week 13

Assignment

Group Assignment:
- Measure the power consumption of an output device
Individual Assignment
- add an output device to a microcontroller board you've designed,
  and program it to do something

Evaluation Standards

Link to the group assignment page
Document how I determined power consumption of an output device with my group
Document what I learned from interfacing output device(s) to microcontroller and controlling the device(s)
Describe my design and fabrication process or link to previous examples
Explaine the programming process/es I used
Outline problems and how I fixed them
Include original design files and code
Include a ‘hero shot/video’ of my board

Output Preview

Roland:MDX-20 FabModules EAGLE Arduino

Group Assignment

Output devices In this assignment we are going to measure the power of an output device using the regulated power supply readings and also using the multimeter
Here is the output device we are going to use for this assignment. A 6V DC motor.

The readings

The power is 0.08*6 = 0.48 watt

Niel's RGB PCB

I wanted To test at frist the Consept of niel's RGB board , So I intend To make his PCB At frist

Frist Open Eagle and start To put the main Components

Component	Quantity
Attiny 45	1
ISP	1
Voltage Reglator 5V	1
Resistor 1K	2
Resistor 499	1
RGB LED 4 Pins	1

And then Go to the Board and start To put the Components and wire them

And then Export Them As PNG

and then go to Modela and Fabricate Your PCB

If You want to know More about how to fabrricate I recommend to you This Electronics Production

Then Solder the PCB

Then Connect the PCB to the USab asp

Then Check that the Computer Can read the board

And then Upload the Following Code

and Voulah ! The Magic Will Apear

MY PCB

In this Part I Ment to Fabricate My Own PCB , It was a little bit Challenging To me but the Result was satsfying To me

And without Further here is the Schematic

And here is the Board

Don't Worry I Will leave the Downloads Files Down

After that I need Now To fabricate the PCB

and Let's Start To Wire Them

And As ususal let's Bring Our asp To start Programming the Circuit

and Let's Upload The Following Code

                                    
                                        #define white 8
#define red 7
#define green 3
#define blue 9

void setup() {
  pinMode(white, OUTPUT);
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
}

void loop() {

  digitalWrite(red, HIGH);
  delay(500);
  digitalWrite(red, LOW);
  digitalWrite(green, HIGH);
  delay(500);
  digitalWrite(green, LOW);
  delay(500);
  digitalWrite(white, HIGH);
  delay(500);
  digitalWrite(white, LOW);
  delay(1000);

}

And Like Magic the Board Works
