How to present stream of independent letters? (Solved)

OS (e.g. Win10):
PsychoPy version (e.g. 1.84.x):

What are you trying to achieve?:

I want to present a stream of different letters that can be differentiated from each other. In case of two identical letters, PsychoPy would show me the same letter but with a longer time duration. Hence, there is no indication that one is dealing with two independent letters. How do I implement a space between my letters?

What did I try to make it work?:

I added second text component that would start at the end of my letter presentation (2s). The text component lasts 0.1s. Be careful with timing. If the time duration of your second text box is too short, PsychoPy won’t be able to display due to the monitor display being 60Hz.

You just enter a non-zero start time for your (single) text stimulus. That way, there will always be a temporal gap between successive stimuli.
