5 second timer circuit diagram. There is a delay before the output turns on.

5 second timer circuit diagram. Orange wave is used to display the discharging capacitor voltage. All the designs are fully adjustable. Figure 2: Basic 555 monostable multivibrator circuit. Oct 13, 2015 · This tutorial covers simple timer circuits using IC 555 in monostable mode. Referring to the timing diagram in figure 3, a low voltage pulse applied to the trigger input (pin 2) causes the output voltage at pin 3 to go from low to high. during the on time it should drive a mechanical relay and after 5 seconds the relay should be turned off as well. Sep 22, 2025 · Learn how the NE555 timer works, datasheet, pinout, and basic stable multivibrator (Free-running) or square wave oscillator circuit. The delay timings are adjustable according to the users personal specs.
