Texas Instruments NE555 Precision Timers IC (SMD Package) B103 10K Ohm Dial Volume-Wheel Potentiometer Long press 5 seconds toThe NE555 Precision Timer ICs are precision timing circuits capable of producing accurate time delays or oscillation. In the time delay or mono stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. Datasheet Features Timing from
