One of the projects I was working on once required a doubling of clock speed from an Arduino Nano, which has anAtmel 328prunning at 16 MHz on-board. I'm going to explain in this piece how I was able todouble clock frequency with digital logic- no PLL or DLL needed! My challenge?
The answer is magnets. By adding a magnet to the bottom of the pendulum, and adjusting the proximity of a metal plate positioned below it, he can speed up or slow down the ticking. The addition of a hall effect sensor lets the Arduino measure the rate of each swing and calculate the ...
