Stepper Motor or Step Motor

Interfacing Stepper Motor with 8051 using Keil C – AT89C51

Stepper Motor A Stepper Motor is a brushless, synchronous DC Motor. It has many applications in the field of robotics and mechatronics. The total rotation of the motor is divided into steps. The angle of a single step is known as the stepper angle of the motor. There are two types of stepper motors Unipolar and Bipolar. Due to the ease of operation unipolar stepper motor is commonly used by electronics hobbyists. For more details please read the article Stepper Motor or Step Motor. Stepper...

Interfacing DC Motor with 8051 using L293D – AT89C51

In some of the electronics projects you may want to control a DC Motor with 8051 microcontroller. The maximum current that can be sourced or sunk from a 8051 microcontroller is 15 mA at 5v. But a DC Motor need currents very much more than that and it need voltages 6v, 12v, 24v etc, depending upon the type of motor used. Another problem is that the back emf produced by the motor may affect the proper functioning of the microcontroller. Due to these reasons we...

16x2 Character LCD

Interfacing LCD with 8051 using Keil C – AT89C51

Liquid Crystal Display (LCD) is very commonly used electronic display module and having a wide range of applications such as calculators, laptops, mobile phones etc. 16x2 character lcd display is very basic module which is commonly used in electronics devices and projects. It can display 2 lines of 16 characters. Each character is displayed using 5x7 or 5x10 pixel matrix. 16x2 Character LCD Interfacing 16x2 LCD with 8051 using Keil C is bit complex because there is no powerful libraries in Keil...

relay

Interfacing Relay with 8051 using Keil C – AT89C51

In some electronic applications we need to switch or control high voltages or high currents. In these cases we may use electromagnetic or solid state relays. For example, it can be used to control home appliances using low power electronic circuits. relay An electromagnetic relay is a switch which is used to switch High Voltage or Current using Low power circuits. It magnetically isolates low power circuits from high power circuits. It is activated by energizing a electromagnet, coil wounded on a soft iron core. For detailed...

AT89C51

LED Blinking using 8051 Microcontroller and Keil C – AT89C51

8051 Microcontroller is a programmable device which is used for controlling purpose. Basically 8051 controller is Mask programmable means it will programmed at the time of manufacturing and will not programmed again, there is a derivative of 8051 microcontroller, 89c51 micro controller which is re-programmable. AT89C51 89c51 is 8-bit device means it is capable of doing 8-bit operations.  It have 4 ports which are used as input or output according to your need. This device also have Timer, Serial Port interface and Interrupt controlling you can use these according to your need. The datasheet may be downloaded from...
