NE555 timer sparks low-cost voltage-to-frequency converter
In 1971, Signeticsβlater Philipsβintroduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50 cents.
