Blinking LED using LPC2148 – ARM Microcontroller Tutorial – Part 3

Hello World In this tutorial we will learn how to start programming an ARM microcontroller. This is a hello world project (blinking an LED) intended for beginners to ARM microcontroller programming. Here we are using LPC2148 ARM microcontroller and Keil IDE for programming. Components Required LPC2148 Development BoardLED220R Resistor Registers In this section we will learn about different registers used for configuring or controlling a pin of an ARM microcontroller. In microcontrollers, pins are divided in to different PORTS. Usually a 32-bit microcontroller will have...

dc motor

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...
