/*
* Device for retrieve coins in a given amount.
Reading: Smart Coin Dispenser
* Works Manually trough keypad presses (only 1 to 9)
* Works remotely with a remote control.
* Works with voice commands trough Alexa or other vice assistants. Need also an Universal Remota Controlfor home automation.
* Make the UR learn the remote control and configura apropriate scenes and routines in Alexa.
*
* Feel free to develop and improve! and please let me know.
