I’m not sure which type of switches to use for the open/closed sensing.
AUTOMATIC CHICKEN COOP DOOR OPENER PROJECT DRIVER
However, as I already have the relays, and NPN transistors, and as the driver array still requires two outputs, I’d rather not spend the money. I know there is a driver array available to drive the motors, instead of using two relays.Again, another switch will input into the chip once the door is closed, stopping the motor and switching on a red LED. At dusk, the chip arms another relay which will drive the motor in the opposite direction (closing). The switch will also turn on an orange LED. Once the door is opened a switch will close, providing an input into the chip and stopping the motor. At dawn (I’ll have to fiddle the ADC value) the chip arms a relay, which will drive the 12V motor and pull up the door. Coupled with a sturdy and reliable guillotine-type door we can hopefully say bye-bye to early mornings! Having discovered the PICAXE last week, I’ve been messing around and I think this is the answer. I actually made an automatic door 5 years back with two mechanical timers and 5 relays, but it was horribly unreliable. The reason for closing the door in the first place is that our area is crawling with foxes and cats who would, given half the chance, quickly run off with one of the ladies during the night. During the summer months they wake VERY early, and if the door isn’t opened for them the chickens get particularly cross. Chickens tend to rise and go to bed with the sun (i.e. So, as the title suggests, I’m making an automatic chicken coop door opener. The aim is to explain my project and attract as many comments and as much criticism as possible so the project can be improved!
Been cruising through for a few days now, looking at all the horribly complex projects all you boffins are completing, and thought I’d chip in with what I’m currently doing/planning to do.
