Square wave signal generator NE555

NE555 duty cycle pulse frequency square wave generator adjustable is a square wave signal generator 5 volts. It generates a square wave signal used for experimental development. Also, it is used to drive a stepper motor to generate a square wave motor signal. The output duty cycle can be adjusted. The duty cycle and frequency cannot be adjusted separately, and adjusting the duty cycle will change the frequency. The output frequency is adjustable: period T = 0.7 (RA + 2 RB) CRA, RB adjustable from 0 to 10 kilo; note when C = 0.001UF; if the capacitor C = 0.1 ultra glow; high-frequency coil C = 1UF; HF capacitor C = 100UF; so buyers can calculate the waveform frequency. Application: as a square wave signal generator, it generates a square wave signal used for experimental development. Used to drive a stepper motor to generate a square wave motor signal. Generate a adjustable pulse for MCU. Generate an adjustable pulse for controlling connected circuits. Features: Generate an adjustable pulse for MCU. Generate an adjustable pulse for controlling connected circuits. The output current can be 15 milliamps; when the power supply is 12 volts, the output current can be 35 milliamps around the output with an LED indicator (low level, LED will light; high level, LED will turn off; low frequency, LED flashes). Maximum output current: >= 15MA (5-volt power supply, V-PP greater than 50%), >= 35MA (12-volt power supply, V-PP greater than 50%).
