Project report - Essay Example Hence, we decided to go for the Bluetooth speaker on a plane that connects to an iOS system. The Bluetooth speaker that connects in an airplane requires everyday materials like LEDs (Light emitting diodes) , an arduino which is an open electronic board based on user friendly hardware and software with a few PWM (Pulse Width Modulation) pins, a Bluetooth low energy shield, a proto shield, a momentary push switch, some copper wire and, an Iphone 4s or an Iphone 5. Ipad (mini, 5, 4) or an Ipod touch 5th generation can also be used in place of the Iphone. Resistors can also be used, but their use is dependent on the type of LEDs we are using. Since, according to Ohm’s law, resistance and voltage are directly proportional to each other if all other things are constant, therefore high voltage LEDs will require a resistor (Instructables.com 2015). The use of low voltage LEDs eliminate the need to use resistors and also help in cutting down the cost. Most of the materials used are readily available in local hardware stores. Usually there exists a BLE (Bluetooth Low Energy) compatible App on the App Store that can get the iOS system to read the BLE compatible device. In case, the user wants to add additional things, a new customized App can be written. The customized app can help run other features that the traditional BLE reader lacks. However, to develop and then run a customized app on an iOS device an extra $100 enrollment fee is required because one needs to be enrolled in the iOS developer program with Apple (Instructables.com 2015). Since, we are trying to cut down on costs we will not write a new customized app in App Store. Instead we will go with the already present App of Red bear Lab’s in the Apple App Store. The project is fairly easy to make and requires very less time. The materials are not ordered; rather they are just bought off shelves from a hardware store or an electrical equipment shop. This eliminates the ordering
