555 Timer (condensed)
Schematic symbol
Timer chip for blinking LEDs, making tones or creating a single timed pulse, with the timing set by external resistors and a capacitor. The classic NE555 runs on 4.5–15 V, while CMOS versions like the TLC555 also work at lower voltages. The output (pin 3) can drive an LED directly but needs a transistor for motors or relays, and RESET (pin 4) should be tied to the positive supply if unused. Learn more about the 555 timer
