Week #7 - Journal

Project Idea:-

The Assignment idea(Smart Motor controller device, With LEDs (Green, Yellow, and Red )changes when an object comes at varying distances from an Ultrasonic sensor module.

To Control the movement of servomotors by two modes:-

1. Controlling by Potintometer

2. Controlling by ultrasonic sensor
   

I care about this idea: to know the basic principles of electrical circuits and electronics which will help me Creating simple Smart Devices that replicate specific functions or perform cool functions. and it's good to make an alarm device and simple piano.

I Searched on the Internet about smart Arduino Device Ideas, I Inspired by this Project:

I had thought that It will be better If I changed the idea by adding LEDs, both LEDs and Servo can be controlled by input from the movement of the potentiometer wiper or sensing from the Ultrasonic sensor

Design Process of the Project:-

1. I searched on the internet about the Sample project circuits Ideas

2. I imagined the schematic diagram of the circuit in my mind, then I sketched it using paper and pen.

3. I searched about the datasheets of all the components to know the (operating voltage and current) and to know to connect the Components together with the Arduino.

4. I opened the Tinkercad

5. I dragged all the components that I will use into the Working Area.

6. I Connected the 5v of Arduino to + on Breadboard and the GRD to the -.

7. I Connected The LEDs with the Resistors to the Breadboard and to the Arduino as it is on the wiring diagram for components with the Arduino board.

8. I Connected The switch to the GND on the breadboard and Vcc with the Arduino.

9. I Connected The Ultrasonic Sensor as it is on the wiring diagram for components with the Arduino board. (VCC to +, GND to -, Trigger to 3 and Echo to 6)

10. I Connected The potentiometer to the GND on the breadboard and Vcc with the Arduino and Signal to A0.

11. I Connected TheServo Motor to the GND on the breadboard and Vcc with the Arduino. Signal to pin 5.

12. I Coding the Arduino MicroController to make the Function of the Device

13. After finishing. I simulated the circuit to make sure that all is ok.

Fabrication Process:-

1. I Used the Simulated diagram for components with the Arduino board to make it.

2. I collected all the parts that I will use to make the circuit device.

3. I joined and assembled the parts of the design together to show the final design of the project on the breadboard.

4. After making sure that all the connections are ok such as the Simultaed device on the Tinkercad.

5. I Connect the Arduino to My PC

6. I Opened Arduino IDE

7. I Uploaded the Programming code to The Arduino Micro Controller.

8. Start powering

9. Here we have the device.

we supported each other to know how to deal with the Electronics and connections and use them, Moreover we helped each other with a lot of problems which occur during the connecting and design.

We supported and helped each other in The Coding Process and we search and find fritzing has all components needed and we can program and export schematic diagrams from it.

The instructors helped us on how to make the week Exercies Projects.

I had some problems with the internet connection and on Recording the Simulation from Pc Screen.

I had some problems with understanding how to connect the Sensors to the Arduino and The Coding Part , After research and (Try & Error) all became ok.

I learned how to:-

1. Understand Arduino Code structure and write Arduino C code syntax correctly

2. Create and Use Variables to store and manipulate different types of data in Arduino C

3. Use Interrupts to do multitasking in Arduino C

4. Understand how code blocks translate into Arduino C programming language

5. Use Looping (for & while) for repeating actions in Arduino C

After this week I learned how to design and program a smart device that performs a certain function or solve a problem: program Arduino UNO to read signals from multiple input components (Sensor, Switch, or variable resistor) to control multiple action components (Motor, Buzzer, LED...etc) using Arduino C Text Code.
