555 Timer PRO

555 Timer PRO provides an array of design wizards, circuit blocks and information panels that facilitate the use of the 555 timer. Component value calculations for the 555 take into account the supply voltage, timer fabrication (CMOS or Bipolar), and, where appropriate, load currents.

        Resistor Color Coder is free, and is very useful for determining the color codes or values of 4 and 5 band resistors. To select the mode, click on the 4 or 5 band resistor icon in the upper right corner of the screen. The lefthand 3 or 4 bands determine resistor value, the righthand band resistor tolerance.

       Features include:
555 timer synopsis - includes pin functions, fabrication differences, component selection

22 timer design wizards - 14 for the astable mode, 8 for the monostable mode
input circuitry - for gating an astable or triggering a monostable. Input categories are switch, touchplate, continuity, liquid level, AC detect, light, sound, and temperature.
counter wizards - facilitate divide by/count to strategies using common binary and decade counters
output circuitry - that can be activated by the 555 timer. Includes switching loads, driving motors, driving LEDs, lamps, numeric and bargraph displays, and audio, ultrasound and RF outputs
general - voltage reference design, "best pair" resistor substitution, logic families reference, IC pinouts for all ICs used in 555 Etcetera
PDF file output - write all project circuit blocks to convenient PDF fil
