Bluetooth adaptors supported by Amarino Shield

BT adaptor

 In Amarino shield version 3.0, there are headers for 3 different bluetooth adapters.

a. General Bluetooth Adapter – Cheapest adapter available at www.buildcircuit.net. RECOMMENDED !

b. BlueSMiRF– Bluetooth Mate Silver– More expensive adapter available on sparkfun.com.

c. BlueSMiRF Gold – The most expensive adapter available on sparkfun.com.

Bluetooth Modules for Amarino shield– Whichever Bluetooth adaptor you are using, the baud rate of Bluetooth adapter should match with the Serial Monitor’s baud rate. For example, if your Arduino source code has

Serial.begin(57600);

then, the baud rate of Bluetooth adapter should also be 57600. The default baud rate of BlueSMiRF module and general adapter is 9600. The shield works excellent with 9600. However, if you want to change the baud rate of BlueSMiRF module, here’s a tutorial.

We don’t know if we can change the baud rate of general Bluetooth adapters with the process mentioned on this tutorial. You can try it.

– This project has been tested with BlueSMiRF module as well as general Bluetooth adapter module and it works well.

Amarino shield 3

CONNECTION: In this experiment, the sensor signal from LM35 temperature sensor is fed to analog pin A0.

Check out the schematic of Amarino Shield 3.0

Steps:

a. Download Amarino and install on your Android Phone.

b. Download Amarino Library for Arduino and move it to the Libraries folder. You can check here if the Amarino team has upgraded the library. It’s always good to use the updated version 🙂 .

c. Download Temperature sensor (with LED controller) application and install on your phone. If you know Android Programming you can download the Android source code also.

d. Download Arduino code for this experiment  and upload to your Arduino. Here, you have to keep few things in mind:

POINT 1: In Amarino 3.0 DIY shield, you have to use the IC1 switch (1 P DIP switch) to switch off CD4094 while doing Amarino related experiments. If it is switched on, the CD4094 chip might affect your experiment.

POINT 2: The Arduino Sketch has its default baud rate set to 9600 bits/s. Therefore, your Bluetooth adapter should also have the same baud rate. Generally, the default baud rate of BlueSMiRF and general Bluetooth adapters is 9600 bps. However, if you want to change baud rate of BlueSMiRF module, follow this link. We have tested this experiment at 57600 bps and 9600 bps and it works perfectly well. You cannot change the baud rate of general Bluetooth adapters 🙁 .

e. Stack the Amarino shield over your Arduino and your Bluetooth adapter over the correct female header on the shield. The shield supports 3 types of Bluetooth adapters. Please check here to know which adapters are supported.

Test if Amarino application connects to the Bluetooth adapter: After installing the adapter on the shield, switch on the Bluetooth function of your phone, open the Amarino application and connect each other using the pairing code 1234. You can see the MAC ID of the Bluetooth adapter on the Amarino application interface. On the image shown below, you can see that there are two Bluetooth adapters with two different names and IDs registered on the application. Pressing the “Connect” button connects the application to the chosen adapter. You can connect only one adapter at one time.

Amarino Interface

A low cost general Bluetooth adapter is enough for this shield. You can purchase one at buildcircuit.net.

If you have never done any experiment related to Bluetooth adapter, we recommend you to try this one… CLICK HERE.

f. Keep the Bluetooth function of your phone alive, pair it up with the Bluetooth adapter using the pairing code: 1234 and note down the MAC ID of your Bluetooth adapter and type it on the text box of your Temperature sensor (with LED controller) application.

g. Connect to the Bluetooth adapter with your application and use the Temperature sensor (with LED controller) application to operate the 5mm white LED with PWM signals and see the temperature data on the application interface.

Steps:

a. Download Amarino and install on your Android Phone.

b. Download Amarino Library for Arduino and move it to the Libraries folder. You can check here if the Amarino team has upgraded the library. It’s always good to use the updated version 🙂 .

c. Download Sensor Graph (with LED controller) application and install on your phone. If you know Android Programming you can download the Android source code also. You can also get the original Amarino source code. The original source code has the Sensor Graph interface only (which means… there is no LED controller slider on the application).

d. Download Arduino code for Sensor Graph (with LED controller)  and upload to your Arduino. Here, you have to keep few things in mind:

POINT 1: In Amarino 3.0 DIY shield, you have to use the IC1 switch (1 P DIP switch) to switch off CD4094 while doing Amarino related experiments. If it is switched on, the CD4094 chip might affect your experiment.

Amarino shield- CD4094 control with Arduino and Android Serial Emulator

Fully assembled kit (4)

This is the second experiment for Amarino shield. If you do not know anything about Amarino toolkit or this shield please click on the following links:

  1. About Amarino toolkit
  2. About Amarino shield

You can get a list of other experiments at the end of this post. Before you try this experiment, we recommend you to try experiment no. 1. In the experiment no.1, you will see how you can control the CD4094 and its corresponding LEDs without using Android phone.

In this experiment, you will see how we can convert a decimal number to its binary form using an Android serial emulator and Amarino shield. On the Amarino shield, you can see that there are 8 pcs of 3mm LEDs which represent the 8 bits. In your experiment, for example,  when you press 255?, you will see that all the LEDs are switched on representing 11111111 that results in actual decimal to binary conversion. Likewise, when you press 1?, you will see LEDs switched on in this pattern: 00000001, i.e. one LED is switched on and other are switched off.

For this experiment, you can use ANY KIND of Android emulator. Here are some examples of Android Serial Emulators. We have used BLUE TERM for this experiment. You can also search this application on your Android phone, it is available on Google Play Store.  Download source code of BLUE TERM(for programmers)

Experiment steps:

Step 1: Download the BLUETERM application or any other general Bluetooth serial emulator for your Android smart phone.

Step 2: DOWNLOAD ARDUINO SOURCE CODE and upload on to your Arduino.

Step 3: Stack the Amarino shield over your Arduino and connect a Bluetooth Adapter.

Please note that the Amarino shield supports 3 different types of Bluetooth Adapters, you can use any one of them. Check out the adapters supported by the shield.

For this experiment, we are using General Bluetooth adapter, the cheapest and the best one. 

The cheapest Bluetooth adapter is available at www.buildcircuit.net. BUY NOW.
Step 4: Connect your phone to Bluetooth adapter using Android Serial Emulator. If you are using the general Bluetooth adapter, the pairing code is 1234. For other adapters also, the pairing code should be 1234.

Step 5: Switch ON the IC1 -1 P DIP switch. If the switch is off, the 10pcs of LEDs connected to CD4094 will not work.

Step 6: Press a number from 0 to 255, and press ? , you will see LEDs responding as binary form of that number.

For example, press 1? glows one LED, i.e. the decimal to 8 bit binary conversion makes… 1= 00000001

or 255? glows all the LEDs, i.e. 255 = 11111111

or 3? glows only two LEDs, i.e. 3 = 00000011

Amarino shield- CD4094 control with Arduino- WITHOUT SMART PHONE

Fully assembled kit (4)

This is the first experiment for Amarino shield. If you do not know anything about Amarino toolkit or this shield please click on the following links:

  1. About Amarino toolkit
  2. About Amarino shield

You can get a list of other experiments at the end of this post.

This experiment has been derived from HEF4794_- Arduino_ Experiment.

This example makes the use of an LED Driver in order to control an almost endless amount of LEDs with only 4 Arduino pins. In this experiment, we use the CD4094 chip. Here, you can get the original version of this experiment: http://www.arduino.cc/en/Tutorial/LEDDriver . The Arduino team has used HEF4794.

An LED Driver has a shift register embedded that will take data in serial format and transfer it to parallel. It is possible to daisy chain this chip increasing the total amount of LEDs by 8 each time. You need to refer to datasheet for connecting more CD4094.

The code example you see here is taking a value stored in the variable dato and showing it as a decoded binary number. E.g. if dato is 1, only the first LED will light up; if dato is 255 all the LEDs will light up.

NOTE:  Switch ON the IC1 -1 P DIP switch. If the switch is off, the 10pcs of LEDs connected to CD4094 will not work.
