Comprising a microprocessor, an LCD, a 32.768-kHz crystal, and little else, the basic countdown-timer circuit in Figure 1 operates from a commonly available CR2032 lithium-coin-cell battery. Based on ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

[FightCube] wrote in recommending a very helpful piece of circuit simulation software for those of you still constructing entries for the 555 design contest. LTSpiceIV, available from Linear ...
