This keychain is a random number generator that is based on the ATtiny13 - an 8 bit microcontroller which is based on the Atmel AVR architecture. The device randomly generates the number 0 or 1. Thus, we can get a Yes / No answer to any question. Indication is carried out using red and green LEDs. If you prefer online generator – spin and pick yes or no through my wheel.
Here is the diagramAs you can see, the circuit is very simple, a few details of everything, this is achieved because the microcontroller is used as the main element.
Why ATtiny13Yes, because it is one of the cheapest Atmel microcontrollers available on the market. Personally, my ATtiny13A costs about 1 dollar. As for me, it is not so much that much as for a key ring. Details on this link
