Fritzing schemas (with trimmer potentiometers)
For timer example, simply remove the 2 potentiometers connected to A4 and A5 analog entries.

Excellent! Looking for this for my project. I tried to use it with I2C LCD but is over my knowledge to modify the library. If, by any chance, do you have some time maybe you will add I2C LCD to this wonderful library! Thanks Wilfried, all the best. Adrian
