Feel free to drop by at one of our weekly Open Garage events on Thursdays.

Make sure to bring a drink (bring whatever you like and share it through our community fridge). We're keeping the empties to cover our (low) budget.

Bring a project that you want to work on. Discuss ideas to get you to the next step. Show your results to fellow nerds, geeks and hackers alike. You're also welcome to just drop by, to check whether the geeky vibe would boost your creativity.

The garage is OPEN, meaning that everyone is welcome, no matter what skills or karma level they are at. Also, feel free to bring your interested friends for a visit.

    Hello everybody, i wont be able to come over there tonight, but i was wondering if somebody knows a good code or instructables for multiplying analog inputs in arduino mega using digital pins. I need to plug 40 analog sensors to it, and have limited amount of them. Any idea? See you soon,

      40 is a lot ... You will indeed have to hook up 5 multiplexing 4051 ICs to get 5 times 8 analog inputs. Getting the code to quickly check all of these analog inputs will be a pain in the ass. Also, the arduino does not have enough digital pins to control all the 4051 ICs so you'll have to multiplex that as well. If you have never worked with ICs and multiplexers this may all sound like a very daunting task but it's not all that bad, just a LOT of wiring.
