HOT WHEELS DRAG RACE FINISH GATE

摘要

On a recent trip to the local kmart, I saw that Mattel had released a series of classic Hot Wheels sets similar to the ones you could buy when I was a kid. I bought one of the two-lane drag race types, with the mechanical flag that flipped one way or the other to indicate which car got to the finish line first. It was the classic drag race toy from my youth. My daughter was fascinated with it, but had a hard time resetting the flag. It would stick sometimes and not indicate any winner. I decided this was a good time to replace mechanical with electronic, and I chose Basic Micro's BasicATOM chip as my solution.
