Adafruit will not be shipping USPS orders Monday February 18, 2019 for the federal holiday, Presidents Day.
Expedited USPS orders placed after 11am ET Friday February 15 will go out Tuesday February 19.
This idea just came to me out of the blue. I couldn’t really find anything quite like it. The original idea was much more involved, so this is a simplified version of the game.
This is a “time bomb”. You have to defuse it before the clock counts down. It uses the accelerometer, sound detection, touch sensors and more to make it difficult to defuse.
This is another perfect application of the Circuit Playground Arduino board! We’re going to make use the built in accelerometer to detect if the bomb is upside down or not, or bumped to hard. The microphone is used to detect too much noise. We’ll also use the neo pixels to indicate how much time is left in addition to the countdown. Finally, we will use the built in touch ability.
The quad alphanumeric display is designed to fit on top of a feather arduino, but its perfectly usable without. Simply connect the power and ground, and the SDL and SCL to the Circuit Playground.
Another nice trick we are employing here is using Play-Doh to simulate the explosive. There’s no Play-doh in Fritzing so you just see wires. Play-Doh makes a decent conductor due to its water and salt content! So the Arduino can detect if the clips are connected or not, through the grounded Play-Doh.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
