I'm looking for a little inspiration for my project. I would like to be able to control a 24v electric gate opening arm via an RPi. (I have my Gert Board kit, but am yet to fire up the soldering iron.)
The system would be powered by a couple of 12v leisure batteries topped up with solar panels.
Control of access options include:
- Keypad access posts either side of the gate.
- RFID swipe token past a sensor.
- XBee/ZigBee transmission of a code?
- Open to other suggestions.
A beam across the gate posts will be required to prevent closing with a vehicle in the way.
Thanks in advance for any suggestions.... I'm a bit lost at the moment!
