Lefty again thank you very much. I will be purchasing that one you mentioned since it came from an Arduino guru himself. smiley-grin plus you gave the library as well for it.
I already made the gizmo for the pet feeder, now it's time to integrate the time module with my newly found 3rd party library.

Thank you Lefty. You have cleared the dust alot there for me. There's no standard library support in Arduino IDE for this, seems weird I thought this might have been built in since handling time is so cool for automation.
Do you know of any other easy way to handle time modules besides the DS 1307 where Arduino is concerned?

Hello,

I have decided to purchase a real time clock module for an automated feeder project I am attempting. I would like it to come on everyday for 7pm using a servo to open a door for the food to come out but I am having some difficulty understanding what is meant by "The DS1307 is accessed via the I2C protocol". In Layman's terms, how exactly do I reference the library to read the time? Do I need to purchase additional hardware?

Thanks.  smiley-cool

Thanks for your response.

It is 4 wires.

Well I've done the beginner topics with the starter kit but Patduino thanks for your recommendation...transistor as a switch. Read some books on beginning with Arduino and did some start up projects but I do think this maybe a little over the edge for me, wanted a bit more of a challenge.
Thanks for the responses.

Hello to all,

This is my first post and I've been doing alot of my research online for this one but can't seem to get a solid grasp of solving this one as I'm new to electronics!!

My question is: I've gotten a 8.4V DC stepper motor from a friend who I think got it from a printer. Seeing that the Arduino pushes 5V max, how do I up the Volts to be able to run the motor? I came across transistors but then the schematics of putting it together is giving me some serious trouble. Am I in the right direction in the first place??? Or should I be looking in a completely different direction? Can anyone point me in the direction of what the schematic would look like?

Any assistance would be deeply appreciated. Thanks a mil in advance for any responses.
Thanks
