Ardunio- Educate Me!

Seeing all the wonderful winners that made stuff out of ardunio and other stuff, I figure that I might want to try doing some stuff using them too. Problem is, I have absolutely no idea how parts work, and I would love to have anyone who's willing point me to places that I might be able to learn the basics of circuit boards, wires, leds, motors, soft/hardware, whatever that's simple to read and learn off of. I know there's tons of Instructables that probably might teach me stuff, but I want to have a general idea first before working. Thanks, username252 (profile image below)

Lilypad RGB led pwm help

Hi everyone, I have started working with my new Lilypad Arduino and some RGB leds.  I have been loading code and testing 4 RGB leds (common anode) which I have set up in parallel across pins 11, 10, and 9.  While powering the lilypad by usb the leds cycle through all colours (which is what I programmed it to do).  Unfortunately, I have a problem when powering the lilypad by  this power supply. When powered by the power supply the only colour that lights up is red (pin 11).  Can anyone suggest anything?

Ardunio Uno Keypad Pin Memory

Hello everyone, I am having trouble making an Arduino code using an Ardunio Uno, and a 4x4 keypad. Quick background, I just started working at a school to help them out with CAD drawings, and they are working on a project.  The students have to make a "cabinet" that has doors or drawers or whatever they wanted.  the door has to lock with a solenoid, and be opened with a pin from a keypad.  The reason is the students will store Ipads in there to charge and so that nothing gets taken. They want the students to put their Ipad into one part of the cabinet, then close the door, lock the door, and put in a pin for that door.  then they want the student to be ale to put in their pin and their door opens.  This would allow each student to put in their own pin, They don't want pre programmed pins as the students that use the room changes over a lot. The biggest trouble so far is none of the teachers know how to make the Ardunio save a pin to memory, and then check the memory when a pin is put in.  So if anyone could help point me in the direction of how to do that, or help with the code hat would be great. Thanks, P.S. I'm a mechanical engineering tech student helping with CAD simply because I know it well enough.  and I don't know much programming.

I want the project to be portable so dont particually want to have a mains water feed. My main issue is the method of spraying the water, Im considering a 12v pump kit but thinking there could be an issue with how far one of these pumps would actually spray the water. I have an ardunio uno and a couple PIRs and dont want to be spending a great amount of money on the project although if i can find a decent method of firing the water then i could increase the budget slightly.  Any ideas or similar projects out there where i might get some inspiration?  Any help would be appriciated

Feature rich servo controller

Hi All, I'd like to write a servo controller that allows another system to offload some of the low level motion control work to the controller. This is primarily for amateur robotics applications. I'm trying to work out whether a controller implementing the features below would be replicating effort of existing open source drivers and not really worth the bother. Has anyone come across an existing controller that can some/any of the following? Position feedback Alterable traversal rate(s) changeable in real time (mid motion) Different seeking modes (acceleration, stall detection, hammering, error margins) Different communication modes (position queuing, position interrupts, upstream arrival and stall messages, etc) and so on... I'm looking at doing this probably with an Ardunio Nano and controlling as many servos as possible, but the primary goal would be feature richness. I could also see applications for an Attiny version (1 controller to 1 or 2 servos, limited feature set). Has anybody got any thoughts on the idea? Thanks in advance, Andy

How can an Arduino be used to show open/closed trading times of stock exchanges within a Time zone clock display?

I'm making a clock display for my wall, with 3 clocks showing the times in NYC, London & Hong Kong. I want to use them partially to monitor each cities' stock exchange (opening & closing trading hours). Is there a way to integrate an Arduino to control two LEDs (1 green 1 red) and turn green for trading hours and Red for closed in each clock? 1 Arduino per clock I assuming.  I have experience with Ardunios and this project will include a Arduino (obviously) breadboard with jumper leads, xbees, LEDs, 9v (a set of all these things per clock I'm guessing), but this is beyond my knowledge base, and wanted to seek the help of those who know more. lf battery life is going to be an issue (always illuminating an LED), 1 green light for open trading could also be used to save electricity.  How can I create an trading hours database, reference GMT time and a script which uses all this data to make a true/false value for an LED to show the current open/closed status? In short how can I bring the project to life? Is it even possible? I would be very grateful for any help. Thanks.
