Hello everyone! In this instructable, I will show you how to make a device that sets off a small alarm when your dog jumps up onto your couch. My dog is so lazy that she probably wouldn't get up anyway, but for regular dogs, it shouldn't be a problem.
Step 1: Parts and Tools
Here are the parts and tools that you will need to complete this project:
Linkit ONE board
Lithium Ion battery (included with board)
Computer with latest version of the arduino IDE and the linkit one drivers
Soldering iron and solder
Desktop printer and paper
Step 2: Wiring
Wire the circuit according to the attached circuit diagram.
Step 3: Code
Download the attached code and press upload.
Step 4: Cut Out Case
Glue the provided template and use a glue stick to glue it to a sheet of acrylic. Now, cut it out on a bandsaw or scroll saw.
Step 5: Glue Case Together
Take the acrylic pieces that you cut out in the previous step and glue them together to form a box.
Step 6: Mount Electronics Into Case
Start by gluing the PIR sensor to the the inside of the enclosure, making sure that the half-dome shaped part is facing upward. Then, glue the Linkit ONE board with a small amount of hot glue.
Step 7: Testing...
To test the device, turn the battery switch on the board so that it is on battery: USB --> BATT. Now, place it on a couch and wait... When a pet jumps onto the couch, it will start beeping and flashing.
