Oh man, if I had that clock on my wall I'd never get any work done! Nicely done!

Education time! Ever wonder how a computer uses electricity to do math? This is an incredible demo (yes it's almost 20 min)  that should take the mystery of how silicon wafers can do math. Demo uses dominoes as electrical charge flow..  What an ending!

This Lipo battery has three wires, as I understand it the third goes to a thermistor. Does anyone know if it needs to be connected up to something when charging? It is a single cell Lipo so I think the third wire shouldn't be required. I imagine on a more complex charger (I am using a max1811 based one) it may be used to monitor temperature.

You need a temp cut off circuit so the battery does not explode.

Someone with great tutorials about magnetometers (I'm using HMC5883L)? I only found copies of the same tutorials of the sparkfun page

Should a digitalWrite remain in effect indefinitely as long as an Arduino remains powered? For my project I write a LOW value and then delay for 24 hours, and find that sometime before then the relay that the pin is connected to has changed state.

My bad: cut and paste code error. Thanks everyone for jumping in to help. And I learned that input values can drift - good to know!

About this community

This is a community for all who enjoy the Arduino platform.
 
I am working to create a new hackerspace that will cater to high school students, and will offer a week long program for basic maker skills (3d design, soldering, and arduino programming). I have been trying to come up with project ideas that we can have pre-printed PCBs for that the students will solder and program. They will be able to take the project home and continue to work on it after the program ends, so it needs to be something fun and engaging that can continually be expanded upon. The ideas should be made as inexpensive as possible, but may include up to 2 servos. Suggestions?

2d LED arrays give lots of room for programming, lots of experience in soldering, are inexpensive, fairly durable, and may be able to run on a single power supply.

This is mi own little "maker space".

Plenty of tools and waiting for more ideas to come!

yah, good idea.  The only thing better than clear labels for components is well documented projects.  XD

Finally made some time to try out the DHT11 Temp and humidity sensor.  Super simple little package.  Wished I had this when I was assembling the High Altitude Balloon data logger.  Cheers.

I prefer the DHT22, a bit more expensive but more accurate.

Ultrasonic Music Played and Measured by Red Pitaya

Careful! The title is misleading, since not much of the music is available at 40 kHz, unless bats are in the audience, of course. And even then, we just wonder about bat’s interest about a single tone.

Taking on the challenge on writing a menu for the Room Management system. Guess it will go above the abilities of the UNO.  If anybody knows how to compact a menu of about 80 menu points, - suggestions are more than welcome since I would like to keep the whole project within the scope of a UNO.
While banging my head on how to keep the Room Management System a stand alone unit and while I am still waiting for some parts to arrive to connect the LCD to the Atmega 328 using only 3 digital pins, I started to write a men...

There's an AnalogButtons library on the Arduino Playground section. I've written my own version of that to solve a few issues and expand on functionalities, I'll share it soon.

Regarding the menu PROGMEM is your only choice: instead of storing the menu strings in SRAM (which is very limited resource) you store it in flash memory (slower, but you have much more space available).

Keep in mind though you are still working with a micro controller, not a CPU with megabytes of space.

+Rick Sellens that is exactly something worth try: can you better explain the algorithm?
