Hi there,
I've found many great examples on how to create a blink without delay in an Arduino loop, but I couldn't find anything about reading the content of a particular excel cell without any wait function.
Is this even possible? Or do you have to wait until you receive the data before continuing the loop?
In my case I want to send data from a sensor, and send the sum of the recorded data to excel using a blink without delay function.
This works perfectly.
At the same time, I want to read a specific cell in Excel and check whether it is 1 or 0. I need to check this say once every second. it's more out less a digital button. In order to read this value, it seems it takes a significant amount of time and the arduino has to wait until the data has been received. Blink without delay doesn't seem to be an option here. Are there alternatives or am I not seeing things clearly...
