Loving this fun water squirting alarm that automatically loads a pic of the newly wet trespasser to Twitter. via instructables
In this project, we will build a water spraying intruder alarm using a Lightblue Bean (a BLE enabled Arduino micro controller). After spraying the intruder, the Lightblue Bean will trigger a nearby computer to take a picture, and upload it to Twitter! We will also be able to remotely arm or disarm the motion detector by sending a message to the Bean through Twitter.
Step 1: Parts and tools
You will need:
Super Soaker Thunderstorm motorized water gun
10K Ohm resistors x 2
4xAA battery holder
An empty toilet paper roll
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
