The idea of creating another function out of the loop seems nicely logic, I will put my needs in pseudo-code and give it a try, give me a few days and I'll tell you how it went.

ok I've got this problem that is driving me crazy. (noob here)

I have two temperature sensors. #1 and #2

I want to read #1, then store the value.

Then, for the next 30 minutes, I want to...

I wanted to make things move. Bought an Arduino, some servos and a power supply. Slowly got into learning c, electronics and the interaction of both.

And here I am! The web is a crazy thing,...

So I guess The easiest, and the right, way to solve this is to wire my sensors to the analog pins of the Arduino. Easy does it!

But then, as I remember CommonTater saying :



then will the...

first, thanks for the All About Circuits link, It seems very complete, sure I'll use it a lot.

for the sensors I use, as I said, I took them from cheap night-lights, but they seem very common,...

I'm not sure I get what resistive dividers are, it seems to be a way to create a ''reference'' voltage, so that if you read a voltage that is different from that reference, then it means something...

I got it!

All servos move together.
I have positioning control.
I have speed control.

And I learned that it's worth it to search the forums for similar problems. Turns out some genius named...

I'll try getting those caps next time I go to the store. Do you mean I should replace the resistor by a capacitor? What is the advantage of doing this?

For the variables, I've done the upgrade,...

A trimmed down version of this program works fine, so the buttons should not be the problem. (they give their signal through the use of a pull-down resistor)

the Arduino board uses a simplified...

it's the first thing the moveServo function does. buttonState takes the value of a button reading, then checks if it has changed from pressed to not-pressed, comparing itself to lastbuttonState. So,...

Hello,

I am working on a project that involves 5 servomotors that need to move in a coordinated way. The servos are controlled via an Arduino micro-controller. I've been learning C through this...
