The 555 timer datasheet specifies that 555 IC is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...

The history of the 555 timer. What are the 555's modes of operation? About my book to help teach those young and old about 555 timers. element14’s 555 timer contest. The 555 timer celebrated the 51st ...

It’s back! The 555 timer contest wants to see you do something cool with the 555 timer chip. At stake is the adulation of electronics geeks everywhere. Three top winners will be awarded a $150 ...

There are several applications at home or industry for long delay timers (ON or OFF delay). Time delays on the order of seconds can be generated using 555 timer circuits, provided the timing capacitor ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...
