And I’m back @Chrisir !!
I decided to try something else with this project and combine the early project with the one above. What I am now trying to achieve is the following:
- First Column appears on screen using typewriter effect.
- It stays on screen by itself for 5 seconds
- Then second line appears also with typewriter effect (it appears on a different part of the screen.
- Both lines of text then stay on screen for five seconds.
- Then the screen goes blank for 5 seconds and then reiterates through programme.
To start, I have been trying to get:
- the first line to stay for 5 seconds (I can’t get this working - although there is a 5 second gap between texts
- then the second one to appear and stay for 5 seconds (Yes, this works!)
- and then screen clears and a gap of 5 seconds before iterating again (This doesn’t work it just reiterates straight away)
So my main problem seems to be with typeWriter1() and case 4:
full code below and any suggestion/advice would be most welcome.
/* This sketch randomly selects rows from a CSV file
these rows are then printed out to screen using
a 'typewriter' style effect.
I want the text to print out and then stay on screen for 5 seconds.
I then want the screen to stay blank for 5 seconds before starting again.
