hello everyone,
I’m new to arduino and currently doing project which is Smart Medicine Dispenser (SMD). this project remind the user to take medicine on time and contain 3 compartment for 3 kinds of medicine. My code below are only for 1 compartment and i don’t know what to add to make it to 3 compartments.
what i initially what to do is for each number user key in, it will represent the delay that the buzzer will activated. for example if the user push 1, the delay will be 1 hour. but in the code below, any number pushed by user the delay is only 10 seconds.
flow of the code :
The user need to key-in time for each compartment and i just use delay instead of using RTC. when the user push a number on keypad, it will be displayed on LCD and time will be delayed for 10 seconds. after 10 seconds, buzzer will activated together with LED and when the user push the button, buzzer and LED will be low. If the button still not pushed, buzzer n LED will continue activated.
what should i add to make the compartment 3?

please help me.
Thank you for reading.
