The microcontroller doesn't need the external resistors and capacitor. If the 555 circuit needs a big capacitor then the microcontroller circuit could be cheaper.
- pjc50 11y agoThe microcontroller does, however, need a decoupling capacitor and the inclusion of a program in manufacturing. It may also be pickier about power supplies.
- mrob 11y agoTrue, but ideally the 555 should have a decoupling capacitor too, and the decoupling capacitor is very small and cheap.
