Hello to all and thanks for the add to your group

Can someone explain why commands start with “Void”. This really baffles me. In Basic, one uses Read, Write, Print and the sort. So, I am sure you can see that I am stumbling when trying to write a “sketch” for Arduino.

Welcome to the forum Dennis,  plenty of oldies here 🙂

void simply declares that a function doesn't return a value.

Learning a new computer language isn't all that difficult,  just one step at a time,  one program example at a time.  A good challenge in keeping the neurons well oiled.

My name is Dennis. I have managed to make it to 72 years old.

Anyhow, I like to fool around with Arduinos of various sizes. Primarily, I like to use them on my N scale model railroad, The Crooked Tie and Rusty Frog

Welcome from another old guy (77) and interested in Arduino and model railroading (HO). There is a forum here in High-Tech Hobbies/Model Railroads which isn't getting much action, but perhaps that will change. There are a few of here who fit in that category!

Hi John,

I am new to forum searching and posting, so it took me a bit of time to locate the forum you mentioned. However, I have joined and look forward to the interaction.

Thanks,

Dennis
