Just wondered if anyone was into coding electronics such as LCD ’s micro controllers, server motors etcs?
Surely there are some electronic geeks out there?
Yeah that shouldn’t be too hard… What board you using?
We’re just using an arduino etherten to control RFID +Garage door while we wait for the raspberry pi’s to be shipped.
Garage door is just a relay on a breadboard connected to the garage door remote: http://gctechspace.org/2011/12/reprap-build-day-ardunio-door-opener/ & http://gctechspace.org/doku.php?id=android_door_entry_system_via_wifi the etherten has a basic http server, and you can ping it from your mobile phone with a password. the etherten checks the password against our gctechspace.org web server (php + mysql db of door codes) and if the password is correct it logs the door open attempt and lets the arduino know it’s ok to open the door.
The rfid was a later addition, connects to the same garage door ardunino http://gctechspace.org/2012/04/rfid-reprap-2/ and uses a kit from freetronics to read the rfid codes and hand them back to the arduino.
We have a few old displays to get working. Some are just rolling LED displays that can be controlled over a serial connection. Some are more complicated LCD displays like from old gameboys. That’s a work in progress and hopefully we can get them going soon
Sounds good to me…
Assuming your ethernet shield is connected to your ONLINE web server, yes the idea is to be able to REMOTELY turn on/off any device in your home, or that is wired to the arduino uno. Looks like you’ve got the uno model there from your pictures.
The code for the ethernet stuff is pretty straight forward, and if you’re just using relays to switch the garage doors on/off you won’t need to worry about bridge rectifiers and dealing with AC voltages.
For LCD ’s I would recommend getting one that has a datasheet so you know the pin outs etc. You could use a gameboy but you would be guessing the pin outs so risk damaging your arduino. The wiring isn’t all that difficult, just need a potentiometer to control the LCD display.
If you have any queries give me a shout, because I’ve already done what you’ve done.
BTW I don’t know anything formal to do with electronic just learning it as I go LOL .
