Why 555 and 556 Timer Circuits Are Essential To Many Types of Digital Electronics
Learning how to build circuits is a lot of fun and can be very useful for projects around the house or to establish a lucrative career in electrical or electronics engineering. There are many resources available online that are free and help you get started easily. One popular circuit to learn is a tutorials on circuits design because of its versatility in a variety of applications. It implements some very basic but powerful electrical components that, when combined, produces a circuit akin to those used in millions of different types of electronics.
555 circuits and projects is based on one powerful integrated circuit (IC) chip. This IC chip is very inexpensive, but its pin output can be quite difficult to understand for novice electronics hobbyists. This is one IC chip that will not produce any type of output by itself. Output meaning a flashing LED, a spinning motor, a buzzer, an input to another circuit, or any other of the limitless applications of these circuits. The IC chip has to be combined with other electronic elements, such as resistors, capacitors, and others depending on the intentions for the output.
It may all seem a bit intimidating, but you will have a lot of resources at your disposal revolving around timer projects, and the internet is a great place to start. Manufacturers of this IC, like those of all other electronic elements, provide a datasheet that you can download for free as a published document file. The datasheet offers a tremendous amount of very specific information about the electrical element, but you will need to take a look at good examples of complete timer projects in order to replicate and understand them fully.
timer circuits with 555 IC are used for timing, but they can be used for much more. When you need a very specific pulse-width modulation circuit, for example, you can use one of these ICs to produce a PWM signal needed to control the speed of a DC motor. A DC motor can only be turned on and off, but with a PWM signal, this on-off sequence can be done rapidly with a certain PWM frequency to control the speed of the motor.
Really to get into electronics design, electrical engineering, or robotics, learning 556 tutorials is a must. You cannot avoid timer projects so you may as well do yourself a favor and begin to understand them early on. Because they are used in very complex electronics does not mean you cannot use them for extremely simple and rudimentary projects.
