At the moment im hopelessly stuck. It literally keeps me awake at night. I hope you might be able to help me out a bit.
What i want is this: I want to send time with a smartphone to my arduino Micro (HC-06 bluetooth module hooked up). (eventually also colorcodes (R G B).) I don't really care if you can only send the systemtime of the smartphone or if you can pick it manually (time picker) and send it to the arduino (DS3231 module).
For the past few days i googled whole of the interwebz but couldnt find anything that gave me that Eureka moment.
my idea is to fetch system time in the app, send it as String (but as an array: HH,MM,SS). I dont know if SoftwareSerial is able to read this (mySerial.readString i guess?). And then somehow convert it to 3 seperate int's (H = (first in the array), M = (second in the array), etc.
Your help is really appreciated!!
Kind regards, Tymen
ps. if someone has an even better idea (or if there is something on the internet that looks like what i want) feel free to share.
