Amarino Shield Experiment 1- RGB multicolor lamp using Amarino shield

Fully assembled kit (4)

This is one of the most interesting experiments that uses Amarino shield and Amarino toolkit application. If you have never heard of Amarino toolkit and the shield, we recommend you to go the following pages:

  1. About Amarino toolkit
  2. About Amarino shield

This experiment with Amarino shield is similar to our previous tutorials on RGB multicolor lamp using Amarino and RGB multicolor lamp with custom Bluetooth ID on Amarino Interface.

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

Multicolor lamp experiment

RGB LED and its connection on the shield:

We have used common cathode RGB LED for the multicolor lamp (RGB lamp) experiment. The connections are as follows

For Red: Digital Pin 3 has been used.

For Green: Digital Pin 6 has been used.

For Blue: Digital Pin 5 has been used.

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 multicolor lamp 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.

d. Download Arduino code for Multicolor Lamp 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 find out 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 RGB Lamp application.

g. Connect to the Bluetooth adapter with your application and operate the RGB LED using the installed Multicolor RGB Lamp application.
