Designing astable circuits using the industry-standard 555 timer is ... Figure 2 The simple addition of a bypass diode makes this timer circuit valid for low duty cycles. Diode forward voltage depends ...

LTSpiceIV, available from Linear Technology, allows you to construct moderately complex 555 driven circuits including common components such as capacitors, resistors, diodes, FETs, and more.

Just about anything can be made with a 555 Timer, and every circuit is fun ... through resistor R2, diodes D1 and D2, potentiometer P1, and capacitor C1 (Fig. 1). 1. Schematic design of the ...

This was shown in the “Inductor-based astable 555 timer circuit”. In Figure 1 ... His current interests include nonlinear phenomena and chaos in circuits, creative approaches to teaching and research, ...

[Diode] can show just what each pin on the chip does, using an outsized schematic that reflects exactly what’s going on with the breadboarded circuit. Most of the demos use the timer chip in ...
