Week 8 - Journal

Steps of implementation on Arduino IDE

1. First, i begin to assign each value that will be used to add the <servo.h> library to read the servo motor and I named it as servoMotor. Then, I set the trigger and echo of the ultrasonic sensor to be able to read the distance of any object correctly. i added then the character of the incoming data that will be sent by the Mobile app and settle it as zero (initial value).

2. Then, in the void setup(), i begin with assigning each pin to its pin number and its state. also i attached the serial monitor code >> Serial. begin (9600) to be able to read the readings on my screen. the RGB LEDS 9,10,11 are as output pins. the servo motor is attached to the pin 3 .

3. Then through the void loop(), i begin with constructing the While condition that illustrate when I added a value the system will act as it. So iadded then the incoming data will be euqal the serial read function. if the incoming data as an example (pressing =1), the motion and light of the RGB LED will act by constrained values. The full path can be illustrated as follows: this is done by adding the Distance order as follows:

4- Then, I opened Arduino IDE and upload it to the Actual Ardunio after porting it with the USB.

Wiring Diagram by using Tinker cad

1. I used the Tinker cad to ONLY simulate the wiring of the circuit.

2. First, I chose from the panel: Ardunio Uno, mini breadboard, Bluetooth Module, Servo Motor, RGB LED, and resistors of 220,560,1k ohms.

3. I supplied the 5 V power pin from Arduino to the + side of the Breadboard and the GRD to the -Ve side of the Breadboard respectively.

4. i placed the RGB LED in the bread board and supplied the common cathode of it with the -Ve of the breadboard. Also for the anodes colors i crossed resistors of 220 ohms along them then to the Arduino digital pins as 9,10,11 respectively.

5. i connected the servo motor to the breadboard by supplying the power pin to the +ve and the GRD to the -Ve of the breadboard. And, the signal pin to the the Digital pin 3 on Arduino.

6. Last, i connected the Bluetooth Module HC-50 to the breadboard by supplying the power pin to the +ve and the GRD to the -Ve of the breadboard. Also, the TXD to the the Digital pin 0 on Arduino and the RXD to Digital pin 1on Arduino. i added 560, 1k as voltage divider 3.3 v.

1. First, I conducted the power by using MM jumper wires on one side along with the mini breadboard and the other on 5V of the Arduino. the same was done for the GRD side.

2. i connected the Bluetooth module HC-50 to the board. there are 4 pins in this module, Vcc to the =Ve of the board, GRD to the -ve of the Board, TXD to pin 0 in the Arduino uno, RXD to the pin1 of the Arduino uno. but the RXD needs to be as 3.3V output, so I added 2 resistors 560 and 1K ohm to act as a divider module (Regulator).

3.Then, I put the slider switch on the lower part of the breadboard. i settled the RGB LEDi placed the RGB LED in the breadboard and supplied the common cathode of it with the -Ve of the breadboard. Also for the anodes colors i crossed resistors of 220 ohms along them then to the Arduino digital pins as red, blue, green 9,10,11 respectively.

4. i connected the Servo motor to the circuit, by adding the power and ground of the motor to the line of the upper slots in the breadboard. Also, the signal pin to the Digital pin 3 on Arduino.

5- Then, I opened Arduino IDE and upload it to the Actual Ardunio after porting it with the USB.

6- Then, I opened Mobile app ( Mobile Bluetooth controller) after i paired it with HC-50 on my phone. i re connect it in the app.

6- As i programmed the code when pressing 1, 2,3 or 4. i made 4 equations by fixing the angle to the RGB led lights.

1. Problem: During practising the turorials, i added the bluetooth module HC-50 to the circuit and then I tried to upload the code to the Arduino. but it uploaded very slow and with errors.

The solution was to upload the code first to Arduino by removing the receiver and transmitter pins of the Bluetooth module, then adding them after uploading.

2. Problem: During practising the turorials, i added the bluetooth module HC-50 to the circuit and then I tried to connect the Bluetooth module with the PC. i paried it successfully, but while uploading the processing file, I see three different names of the Module to add in the code. and i didnot know which one to add.

The solution was that i opened the bluetooth options and read the name that the device configured my module. then i added it in the code and it works!
