Tag: 555 timer circuits

555 timer IC is an integrated circuit used in a variety of timer, pulse generation circuit, and oscillator circuit applications. The 555 can be used to provide time delays, as an oscillator, and as a flip flop element.

555 Led Dimmer Circuit IRFZ44

The Led dimmer circuit you see in the diagram works like a DC dimmer, the brightness of a number of led groups can be increased or decreased. The supply of the circuit is + 12V and the led groups are grouped in series and parallel so as not to exceed the circuit supply. The circuit

Soft Start Circuit For DC motors

Electric motors, in addition to many obvious advantages, also have some disadvantages. One of them is the consumption of a much higher current during start-up compared to the current consumed during normal operation, which can overload the power supply. The schematic diagram of the “soft start” system is shown in figure. The multivibrator with the

Phone Ring Amplifier Circuit

Phone Ring Amplifier Circuit People with hearing problems do not hear a phone call or intercom. Often the reason is the low volume of the bell built into the device. This project can eliminate this problem. This project is not an amplifier in the literal sense. Rather, it can be called a sound comparator, which

12V 24V 10A PWM Control Dimmer of Speed for DC Motor

NE555 10A PWM Circuit TECHNICAL CHARACTERISTICS – Power supply: 12 to 24 VDC – Maximum output current: 10 A – Designed for low voltage motors – Adjustable frequency between 300 Hz and about 2 kHz – Current protection adjustable between 0 and 10 A – Rotation speed adjustable between 0 and 100% – MOSFET with

NE555 Super Siren Circuit

The first block is built on the NE555, which acts as a free-wave generator. VR1 50k potentiometer and C1 capacitor and VR3 100k potentiometer and capacitor C2 are responsible for the “rotation” speed. The VR3 potentiometer at maximum resistance increases the rotation speed. The rotation speed is in the range of 20 … 75 Hz.
