1 × RGB COLOUR SENSOR complete color detector including RGB sensor chip and it can detect and measure a nearly limitless range of visible colors
1 × ARDUINO UNO Arduino is a microcontroller-based kits of computer hardware for building digital devices and interactive objects that can sense and control objects and the physical world. It read pulses from a scanner that detect the currency; the sketch of an image will be uploaded to the Arduino using the scanner then some coding will be inserted by special software to identified or make a differences in the value of each notes
1 × SPEAKER Speaker is a device that give an output from our system.It gives a sound of each value of the note that we inserted under the colour sensor.It connected with the system and get the code from the Arduino to be functioned
1 × MP3 MODULE(DF MINI PLAYER) it is a small and low price MP3 module with an simplified output directly to the speaker.It also can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with an Arduino UNO or any other with RX/TX capabilities.The audio data sorted by folder and can supports up to 100 folders, every folder can hold up to 255 songs
1 × RECHARGEABLE BATTERY it is use to power up all the components.The battery used is Lippo battery of 7.4v and 1300mAh
20 × CONNECTING WIRES it is used to connect the components
1 × BATTERY CONNECTOR it used to connect the battery to the Arduino.It should be thick wire to avoid melting if short circuit occurred
1 × PUSH BUTTON
