I’ll try to explain my project concisely and accurately. It is for a competitive animatronic event and the prompt is an exhibit in a space history museum. My group is making a simulated shuttle launch. So the one minute count down is the launch timer for t- and the timer after is my t+. The count down can’t start until 3 switches are on and a button is pressed, which I am using a limit switch. The system cannot be affected while it is running which means that what ever happens to the switches during the program must not affect it. I have the switch and button figured out already. During the count down there are multiple events such as audio playing or LEDs turning on and off. I have a second Arduino that is controlling the events and my first Arduino with the seven segment display has the timer everything is based on. I’ve already figured out how to active the events on the second arduino when the timer on the first Arduino is on the time that the event needs to happen. My display variable is clearly changing when the count down is activated, but not all digits are lit at a time. I’ll take a video today to demonstrate.
Does millis(); just function as a running timer. I am still a coding beginner and everything I know is because of this project.
I won’t be able to post the code until Monday, but I have a working code for what I need.
I just need to figure out how to use an SD card reader but to play different audios.
