IC

IC is the general tag for any circuit that contains an integrated circuit from DCACLab's IC library, a packaged chip with numbered pins wired up from its datasheet pinout. Named chips also get their own tag, so 555 timer circuits are listed under 555 and adjustable regulators under LM317, while this page collects all of them: timers, flashers, PWM motor drivers and regulated power supplies. For example, "DC Motor Controller" drives a fan motor from a 555 timer through a transistor, with a potentiometer setting the speed.
