555 Timer Calculator

The 555 timer is a commonly used integrated circuit that can be configured to produce a square waveform output. In Astable configuration the output will be a free running squarewave output. In Monostable mode the output will be a single high pulse generated for a single input event. This calculator will determine the pulse width of the output based on the resistance and capacitance values entered.
