The 555 Timer is a very cheap, popular and useful precision timing device that can act as either a simple timer to generate single pulses or long time delays, or as a relaxation oscillator producing stabilized waveforms of varying duty cycles from 50 to 100%. The 555 timer chip is extremely robust and stable 8-pin device that can be operated either as a very accurate Monostable, Bistable or Astable Multivibrator to produce a variety of applications such as one-shot or delay timers, pulse generation, LED and lamp flashers, alarms and tone generation, logic clocks, frequency division, power supplies and converters etc, in fact any circuit that requires some form of time control as the list is endless.
By wathcing this video, you can understand PID in just 4 minutes. More explanation is given below on this website.
There are four different types of controllers and these are P, PI, PD and PID explanined below.
Radio-controlled cars, boats, airplanes, etc use servos to control steering and other functions. The interface is well defined and the servos are quite affordable, so they are also used for robotics and other clever purposes. The servo positions itself based on the width of positive pulses fed to it. The rate at which pulses are sent to the servo is relatively unimportant(40 per second seems pretty typical).A servo motor has an output shaft that can be positioned by an encoded control signal. The motor drives the angular position of the controlled device.
Servo motors have three wires:
The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard which opererate in a full duplex mode. Devices communicate in master or slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select lines with the chip select.
For communication with outside world and other components microcontroller uses many different kinds of communication. Here you will find detailed explanation on how each of these communication protocols. Details of principles how the work, what you must know before you can use them. And when finished here you can go to tutorial sections for specific family and get complete example codes and detailed description on specific microcontroller family. These are UART, I2C, SPI, USB…
Basic functions that every device does are measurement and control. That is why it is important to know how to properly measure something and what sensor to use.. Here you will find explanations on these topics to help you with implementing hardware for your microcontroller project.
As previously mentioned Control is one of most important things in every project. Weather you need to control some DC motor using PWM, timer circuits with NE555, Using servo motors, Using PID regulation or any kind or regulation you will find useful articles here describing basic term from this are that you need to know before you can start making your project. Here are mentioned only few of areas this category of www.electronics-base.com covers. PLL frequency regulation… list is endless. When you get the basics you can get example codes written in microcontroller C compiles on tutorials page or find complete project with source code and all documentation in projects section of the site.
General descriptions not fitted in any specific category from field of electronics.
General explanations about microcontroller specific topics. What are GPIO pins, TTL levels, Reset circuit.. If you have just started to work with microcontrollers and do not have much knowledge about them than here are useful texts to read before you go to tutorials or complete projects section of www.electronics-base.com and continue learning about world of intelligent electronics.
