What do you do when you forget a 3 number combiniation where each number could be 1-100? byte sized engineering works up this stepper motor solution with a bit of Adafruit gear!
This is just part 1, follow along to see if they get the safe open!
He sat down for hours and hours trying all the different numbers he could think of to no avail. The safe has been sitting locked in his house for more than two years! That’s when Levy called me. There are 100 numbers on the dial, and the combination has 3 numbers, so there are a total of 1,000,000 possible combinations! There is no way someone could try all of those by hand; that would take several lifetimes. But if I can find a way to test combinations quickly (and maybe find a way to reduce the number of possible combinations) this might be doable!
I’m not a locksmith, nor do I have any burglar skills, but I am good at engineering, problem-solving, and building things, so I’m going to try to build a robot that can crack the combination to Levy’s safe.
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.
