Week 8 # - Journal

Night Lamp

The assignment of this week to Communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) on your phone or PC.

When the weather get Cold we need a smart Night Lamp we can control it by mobile app. and give us a cool colors and music while we are going sleep .

the Night Lamp has many colored light emitted from RGB LED and a strong light from 220 V lamp and controlled it by mobile app .

So I Built a simple smart circuit that contains Three action components ( RGB Led , Buzzer and Lamp with Relay Module ) and controlled it wirelessly by Android GUI on my phone.

Software :

1- TinkerCad Portal : to build and simulate the circuit online

2- The open-source Arduino Software (IDE) : to write code and upload it to the Arduino board.

3- Android Bluetooth Control App. to create the mobile app.

Materials :

§ 1 Android Phone

§ 1 Arduino Uno Board

§ 1 RGB LED

§ 3 Resistors 220 Ohm

§ 1 Lamp

§ 1 Relay Module

§ 1 Bluetooth Module (HC-06)

§ Jumper Wires

§ 1 Adapters (5 V)

§ 1 small Breadboard

Step 1 : Test RGB LED

• Design a circuit of Arduino board and RGB LED with 3 resistors ( 220 Ohm) as shown in the picture.

• Make it in actual Arduino Board and Breadboard.

• then write a c code to RGB LED to emit red color for 0.5 second then green color for 0.5 second then blue color for 0.5 second then white color for 0.5 second.

Step2 :

• add a buzzer to the circuit and write C code to do the same action with RGB LED and make a different tone from the buzzer with each emitted color.

Step 3 : test a relay and 220 v Lamp:

• Design a circuit of a relay with 220v source and a Lamp as shown in the picture and write the next code to turn on the lamp for 2 second and turn off it for 2 second.

• after uploading the code to Arduino the circuit doesn't work and after checking the circuit and insure its right i decide to replace the relay with another one.

• after replacing the relay the circuit works fine and the lamp turned on and off.

Step 4: Test the Bluetooth

• Design a circuit of Arduino board and HC-06 Bluetooth Module and LED and 220 ohm Resistor as shown in the picture.

• Do it in actual component.

• Write a C code to test the Bluetooth.

• if the Bluetooth receive '1' the LED turned on and if the Bluetooth receive '2' the LED turned off.

• open my mobile phone and Pairing the mobile Bluetooth with HC-06 Bluetooth module

• open the Android Bluetooth Control App. and it connected with HC-06 module.

• Press on Buttons and slider button then I used the first two buttons which send '1' and '2' via Bluetooth.

• when press the first button the led turned on and when press the second button the led turned off .

Step 7 : Integration :

• integrate RGB LED , buzzer , Relay and Bluetooth circuits in one circuit as shown in the picture.

• Write a C code to do :

• § When receiving number '1' turn on the Red color only in RGB Led and play a tone from the buzzer.

• § When receiving number '2' turn on the Green color only in RGB Led and play another tone from the buzzer.

• § When receiving number '3' turn on the Blue color only in RGB Led and play another tone from the buzzer.

• § When receiving number '4' turn on the White color only in RGB Led and play another tone from the buzzer.

• § When receiving number '5' turn on the Lamp with Relay module only and play another tone from the buzzer.

• § When receiving number '6' turn off RGB LED and the Lamp.

2- print the faces of the cube with square holes in sick white paper.

3- cut the squares by cutter

4- assemble the faces of the cube with each others.

5- put a Transparent paper inside the faces of the cube.

6- final enclosure

7- put the circuit in the enclosure

Step 9 :Test the final project
