Finalize components
Objective : To finalize and decide changes of component to be used for the project
Activity : I need to reconsider back components that needed to be used in this project. The main component that i would like to change is the microcontroller model which from Arduino Uno to Ardui Nano. This is because the project should be wearable device on wrist so I need to make surethe project in compact size which the dimension is only 43mm x 18mm compared to Uno 68.6mm x 53.3mm. This is the different of size between this two Arduino.
Even their size is different but most of the pin and function almost same which Uno have 6 analog input 14 digital output while Nano have 8 analog input with 14 digital output. Besides, both have same clock speed and flash memory which is 16Mhz and 32kB accordingly. The other difference of this two model of Arduino is the external power source which Uno using USB while Nano using Mini-B USB connection.
Conclusion: The Arduino Nano is more suitable to be used for the project because of it size that more compact.
