BLUE TERM APP FOR ANDROID

Blue term description:

VT-100 terminal emulator is a program for communicating with any serial device using a Bluetooth serial adapter. The RFCOMM/SPP protocol emulates serial communications over Bluetooth.

This is an open source application.

CONNECT AN ARDUINO TO BLUETOOTH MODULE (HC-05)

Arduino and Bluetooth HC-05 connecting easily.

Today, I connected my Arduino Uno board to the Bluetooth module HC-05 in order to communicate with my Android smartphone. The HC-05 Bluetooth module and its siblings are far the most popular and inexpensive Bluetooth module used for RF communications by Arduino as a microcontroller.

Then, the image below show the Bluetooth with offers 4 pin outs. Its for 5V, Ground, RX, and TX that have to connect with the right pins on Arduino Uno board. The advantage of this HC-05 module, is we did not need an additional electronic parts.

The way to connect the Bluetooth nee to identify the 5V and Ground Arduino pins on my Arduino. It is to provide the power source for activating the Bluetooth module. GND is of course connected to the GND of Arduino. Next, connect the Bluetooth module's RX pin to the Arduino's TX pin, then connect the Bluetooth module's TX pin with the Arduino's RX pin. The figure below show the Bluetooth connected.

After connecting the Bluetooth serial module with Arduino,we are able to pair the HC-05 with any Bluetooth enables device. As a password to pair, I am using '1234" as a pairing key. After pairing is successful between the devices, the LED indicator will turn "on", like the picture below:

LDR MODULE

LDR Module is a light sensor. Also known as Light Dependent Resistor. (LDR).

Typically, the resistance of the light sensor will decrease when the ambient light intensity increase. The features of LDR Module are discussing below;

• Can detect ambient brightness and light intensity
• Adjustable sensitivity (by drop any object in front)
• Operating voltage almost 3.3V-5V
• Output type ; analog voltage output -A0 
• With fixed bolt hole for easy installation
• Just a small board PCB
• Size : 3cm * 1.6cm
• Power indicator (red) and the digital switch output indicator (green)
• Stable and small plate
• External GND GND
• A0 small board analog output interface

How to used:

• Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect ambient brightness and light intensity.
• As a module light conditions or light intensity reach the set threshold.
• Detecting the ambient light intensity changes
• Digital output module , DO can directly drive the relay module, which can be composed of photoelectric switch.
• Analog output module AO connected to the converter then we can get a more accurate light intensity value.

GPS ANTENNA 3M LENGTH FOR ARDUINO

GPA Antenna used to received a signal from satellite. This antenna is needed to place at open area workplace. This is because GPS have an unit typically which is will NOT WORKS indoor, underwater or underground.

The picture show that the GPS Antenna for Arduino GPS Shield cable lenght 3M.

So, the combination of GPS Shield + GPS Antenna 3M length for Arduino Uno is shown below:

GPS SHIELD ARDUINO V3.0

Arduino GPS shield is a GPS module bread out broad designed for Global Positioning System receiver with SD interface. It is easy to use for recording the position data into SD card.

The figure show that the chip of the GPS Shield Arduino V3.0.

The features of this GPS Shield Antenna:

• with micro SD interface
• active antenna design with high receive sensitivity, compatible normal antenna
• extremely fast time to first fix at low signal level
• UART interface
• Operation tem perature just nice. (-40deg ~+85deg)

RESULT & ANALYSIS (GPSSCREEN)

The coding blinking has been download to my Arduino Uno Board. The Figure above shown that the led is blinking.

To download any coding to Arduino controller, here is the step has to follow:

1. Compile the coding
2. Download
3. Conclusion

• Here is the compile session.

As in figure above, after finish the coding, we need to click the right symbol (√). Then it will compiling the coding and check whether the code.

Any error of the code will be display at the black screen. After the compiling is finished , it will display as picture shown below.

• Here is the second step is download.

To download the coding, first. Click the (->) symbol ad shown in figure above. Then, wait for device to downloading.

After the downloading is finished, it will shown like the figure below:

Now, the coding has been downloaded to the Arduino Uno board. Lastly, the project is in progress to develop.
