9V to 5V converter schematic with 555
A 555 timer can be used to generate a square wave to produce a negative voltage relative to the negative battery terminal. When the timer output at pin 3 goes positive, the series 22 uF capacitor charges through the diode...
Linear frequency meter
The 555 timer is utilized in a monostable multivibrator circuit that generates a pulse of fixed time width, which is activated by an unknown input frequency.
The 555 timer in a monostable configuration operates by producing a single output pulse in...
simple fluorescent inverter project
Fluorescent tubes contain mercury, which poses health risks. Improper disposal of these tubes is harmful to both the environment and health; therefore, recycling is a beneficial option. The 555 timer IC is utilized to generate a square wave voltage of...
Over-Under Voltage Cut-Out with 555
This over/under voltage cut-out will save your costly electrical and electronic appliances from the adverse effects of very high and very low mains voltages. The circuit features auto reset and utilises easily available components. It makes use of the comparators...
Sequential Flasher Circuit
A 555 timer (IC1) controls a 4017 CMOS decade counter. The first four outputs of the 4017 drive a CA3079 zero-voltage switch. Pin 9 of the CA3079 is utilized to inhibit output from pin 4, effectively disabling the stream of...
555 Composition with Watchdog circuit
This circuit was originally a type of power-delay control circuit, where the delay time is determined by the timing elements R1 and C1. Additionally, with the inclusion of a "watchdog" circuit, it can be utilized as a monitoring circuit for...
Push Off Push On
The widely used 555 timer is utilized in a bistable configuration that employs a simple push-button for a push-on, push-off action. This configuration operates on the principle of maintaining a stored charge in a capacitor, which manipulates a Schmitt trigger...
555 tone generator circuit
This circuit combines the outputs from two distinct 555 multivibrators using a summing operational amplifier (Op Amp). It serves to illustrate an alternative implementation of a 555 timer, with most background calculations addressed in other sections. The standard configuration for...
The motorcycle anti-theft alarm (3)
This article introduces a motorcycle anti-theft alarm that utilizes the 555 timer integrated circuit. The alarm is activated when a thief attempts to move the motorcycle vertically. The circuit consists of a trigger circuit and an alarm circuit, as illustrated...
