Description
555 Adjustable Duty Cycle and Frequency
Easy to use 555 oscillator with potentiometers to adjust duty cycle and frequency.
The 5 pin header can plug into a breadboard and an external capacitor can be added on the breadboard to modify the frequency control range.
With the part values used in the design, depending on the capacitor chosen,
frequency can be adjusted from below 1 Hz to around 400 KHz and depending on the frequency chosen,
duty cycle can range from below 10% to over 90%.
