Showing […]
LED Scrolling Display Board This article explains the steps involved in designing a scrolling message LED Display. The following features of the display are explained in the article. Framing Alpha-Numeric characters and special characters Multiplexing the matrices Serial mode of data distribution using shift registers Static text display Scrolling text display Mode selection between static
Musical Keyboard Using ATMEGA8 Â This article aims at developing a Monophonic (Single note) musical keyboard by generating the musical notes frequencies using a microcontroller (ATMEGA8). The project presented in this article is a 12 Key, Monophonic keyboard with the options To shift between the Higher and lower octaves Play the programmed tunes Record and
GPS Vehicle Tracking System This article mainly focuses on the idea and logic behind GPS Vehicle Tracking System with remote monitoring and security access using mobile phone. The GPS-GSM module is interfaced using a single microcontroller and the real-time GPS location of the system is inquired using SMS feature. The system is designed to operate
The main objective of this project is to control the ON/OFF status of electrical appliances at home or company remotely using a cell phone and relay switch. The appliances may include lights, fans, pump, and air conditioners and so on. Though all the household items can be automated to change their ON/OFF status, our prototype
One of the most enjoyable part of being an electronics person is creating your own gadgets and using them in daily life. In this article, we are building one of those with the help of SoloPCB design tools, a digital desk clock with temperature display feature. The brain of the circuit is a Microchip
In this article, we have come up with a new PIC micro controller project. Our author Mithun has created a Digital Voltmeter Circuit using PIC16F73A and multiplexed 7 segment displays. The circuit is well explained with diagrams and the source code (written in Embedded C language) is available for download. Â If you have any doubts
So you may have guessed something from the name itself – “Special Function Registers” known with an acronym SFR. Well, your guess is right 🙂 Okay! Lets come to the point. There are 21 Special function registers (SFR) in 8051 micro controller and this includes Register A, Register B, Processor Status Word (PSW), PCON etc
In this article, we teach you about 8051 addressing modes. If you’re familiar with 8051 already, you may know an addressing mode is a way to address an operand. If you are new, don’t worry – we’ve covered every aspect about 8051 addressing modes in detail. Let’s begin the journey. Lets begin this article with
A micro controller is an integrated circuit or a chip with a processor and other support devices like program memory, data memory, I/O ports, serial communication interface etc integrated together. Unlike a microprocessor (ex: Intel 8085), a microcontroller does not require any external interfacing of support devices. Intel 8051 is the most popular microcontroller ever
When you start learning about Microprocessors (in most cases you will begin with Intel 8085) and Microcontrollers (usually you will begin with Intel 8051 from the MCS 51 micro controller family), the first question that pops up is “hey… what’s the difference in between”? In this article, I am explaining the basic differences and similarities
Six pin Microcontrollers from Atmel-AVR ATtiny10 The latest AVR ATtiny10 is highly suitable for large volume market applications. AVR ATtiny10 has 1kilobytes of programmable flash memory, 32 bytes of internal Static Ram, 8-bit Analog to Digital converter, a 16-bit timer with Pulse Width Modulation, 12 MIPS of processing throughput and an analog comparator.Using the AVR
