In an astable configuration, the 555 timer outputs a continuous stream of rectangular pulses at a specific frequency. RA Vcc ww Reset1 = - Threshold1 Controll Ground ㅋ Use your breadboard to construct the circuit Discharge1 shown as a schematic below. Use R1 = 47 k22, Output1 R23 R2 = 180 k 2, and C1 = 10 uF. Trigger 1 When it is working the LED should flash. In preparations, Th and T, were calculated by the formulae provided and measured in simulation. C 100 nF Now, use oscilloscope to measure Th and Ti. Connect Channel1 to Output1. Figure 2-5 Astable configuration Based on the measurements, complete the following table: Table 2.5 Astable pulse width measurements Frequency Period Tn T Duty Cycle f (Hz) T(S) (S) (s) (%) Formula 0.0000 306 32700 1658 1.25 Simulation Experiment
