This is the automatical sonorised entrance of my garden for the Halloween 2017.
This year for Halloween, I wanted to make a cool automatical entrance, so I've do this. Hope you enjoy. ^^
This is only a no definitive prototype, so I've don't made any instructions because the pieces are bad quality, not solid and not sustainable. But I've made some explaination of how it's work.
Instructions maybe for the next year, when I'd have a 3 priner, so be patient...
PS: Please be indulgent on the spelling of my instructables because english isn't my native language.
Step 1: Electronic and Mecanic Parts
Image 1 : The motor parts for the door opening.
Image 2 : The trapdoor access.
Image 3 : View of the mecanicals parts wich make moved the skull head.
Image 4 : Stop moved buttons.
Image 5 : The song module.
Image 6 : The elctronic arduino control card.
I've used an Arduino Nano wich is attach to:
-a L293DNE H-bridge, wich is control the moving of the head, attach to a 9 volts battery for the 9 volts motor.
-a L298N H-bridge, wich is control the moving of the entrance gate, attach to a 12 volts battery for the 12 volts motor.
-the eyes LEDs of the skull.
-a big red button.
-a song module.
-and 2 end-of-stroke buttons.
Step 2: How It's Work ?
When someone push on the big red button, The head is stand up, the eyes become red, and it's said: "Wahaha ! Welcome ! Wahaha !"
The eyes are switching off, the head is going down, and the 12 volts motor start to open the gate. When the gate activate the first end-of-storke button, the motor is switching off, the Arduino wait during 4 seconds, and the motor turn in the other direction. And finally when the gate activate the second end-of-storke button the motor is switching off, and the system is waiting for someone push again on the big red button.
Step 3: Final Prototype
Final prototype and instructions maybe for the next year, when I'd have a 3 printer, so be patient...
