LCD is Alive!

Our 4 line 20 character white on blue display from Hacktronics is alive and well. I uploaded the sample sketch and wired the display according to the tutorial that is posted on their website, and everything worked like a charm. Next step is to read the temp sensor and display the current temperature (current values displayed are a mock-up, not being read from a sensor). I need to get a 5k ohm pull up resistor, so stay tuned!

Update: got the resistor, but having problems uploading the onewire.h library

BTW, the Hacktronics LCD Tutorial also worked with the what was previously thought to be a "dead" 2 line Black on Orange LCD display we recieved earlier from GE Tech. Now I have two LCD's to play with.

What is Hackspace?

Hackspace is a local geek club for playing with electronics and computers. Ok, could I get more condescending? Hey, I'm a linux / microprocessor geek myself. Anyway, a local club develops with a facility and tools that are shared with members, and there are usually official hack nights, as well as drop by and work times. Bulk buys are usually available, and members share skills and ideas. Check one out near you, or start one yourself.
