Do you have many Super Mario Bros collectibles, such as Mario Bros candy tin? In this case, would you want to use the candy tin and do something interesting?
Well, you’re very lucky, as today you have the chance to develop the USB powered blinking and singing IR Mario Bros sensor!
Honestly, this is an easy project, which with an attiny13A , an IR motion sensor and a candy Mario Bros mushroom tin, you might turn it into a USB powered IR sensor.
In this project, all the electronics are fully-powered by a USB cable. An external IR sensor is being used for detecting motion, which triggers the LED and musical sequence. By the way, the attiny13A need to be programmed first, as it’s for controlling the blink on and off function, before it jumps into the musical sequence.
The LEDs blink to the tune of Super Mario Bros and the speaker can be easily shut off, by tuning the switch that attached onto the speaker!
You know what; the total cost of materials for this project is less than US$20, which is extremely cheap and affordable. So, let’s go and build one, either for your own use or your loved ones!
