 Early data, what is this? This is a miniature like model train or like model city or architectural model stoplight. And I thought this was a really adorable little device that maybe engineers could use. I've got it wired up to an Arduino Metro mini and the wires are really thin. So I just kind of got them stuck in here but it's good enough to test. The black wire goes to plus five volts and then you just connect red, yellow and green to digital IO and then I've got a little bit of Arduino code just to test it out. But I just thought this was so cute. I mean, like maybe people making electronic doll houses or something can use this cute little model. A necklace. A necklace maybe. Yeah, like stop red, green go. And I also got this interesting kind of like test clip which is 0.1 inch spacing and you just clip it on. Very handy maybe for debugging or programming.
