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.

CNC Motor Driver Tester

The purpose of the Motor Driver Test card is to check any of the motor drivers used especially in CNC machines. The tester is connected directly to the motor driver board instead of the interface. The tester has 4 switches that determine the state of Direction Signals (change direction of rotation), Enable (drive enable), Step

Water Level Control Automatic Tank Filling

Simple 555 circuit. The water tank filling circuit is based on the NE555 timer IC. By measuring the water level in the tank, it automatically starts the water pump motor at low water level and stops the water motor when the water in the tank reaches the specified level. The circuit can be used for

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.

The Domino Effect With 555 Circuit

It’s quite strange that so many projects are being done with some 555 circuits. “Domino’s” 555 timer 555 circuit is an interesting electronic circuit with a chip that is prepared based on the different LEDs and photodiodes made a lot from each other they trigger it’s a domino effect, the author is also the project
