iButtons & 1wire are the same thing, the iButtons come in a package that looks like a large watch battery, the 1wire are the chip versions.
What I'm after is the specs for that door striker. A 9V battery may not work.
Nice, the 12V DC ones would use 500ma which is about the limit of that wee reed relay and may eventually wear out the contacts due to pitting. The second relay would be a better match IMO. You will need the driver transistor for that one though. What are you using for a key?
Here is an iButton lock device, your Junebugs tutor could be programmed to do the same. Download the manual as it includes a schematic for a PIC16F84 and a relay. **broken link removed** **broken link removed**
Im making a remote with 4 buttons and you have to enter the buttons in a specific order for the remote to send the special address code and command to the receiver.
The combination will be from 3-5 strokes of my choice and order.
the issue there is anyone can use that key. My key will stay home most the time and will want to use from far.. like to let others in .. wireless and distance count here.
