With an attiny13A, an IR motion sensor, and a candy Mario Brothers mushroom tin, this project turns them into a USB powered IR sensor that also blinks and sings. This is a variation of the marioman project but unlike that one this *this* is practical 😉
Here are the features:
The container for the project is a metal Super Mario Bro candy tin
Electronics are powered by a USB cable (for 5v)
An external, attached, IR sensor is used to detect motion which triggers the LED and musical sequence.
The attiny13A is programmed to blink on and off first for a set duration, then jump into the musical sequence.
The LEDs blink to the tune of super mario brothers
The speaker can be shut off by a switch attached to the speaker

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.
