A speedometer is a speed measuring gauge used to calculate the speed of motor vehicles. They are mainly of two types- electronics and mechanical. A digital speedometer measures the speed and mileage in vehicles. Normally both types work on the principle of electromagnetism, however, they have a disadvantage in that they cannot be used if there are no wheels on the moving … [Read more...] about Simple Digital GPS Speedometer Using PIC16F877A with LCD Display

SMS Based Device Control using GSM Modem
GSM-based device monitoring and control systems are becoming popular these days. Here I am introducing a system that will make home appliances controlling using mobile phones possible from anywhere in the world. It’s a PIC microcontroller-based system that connects with the GSM module to receive SMS for smart home control. The message is then processed by the … [Read more...] about SMS Based Device Control using GSM Modem
Car Anti theft System Project using Microcontroller PIC16f73
Here is an outstanding one that is not only suitable for electronics engineering but mechanical engineering students too. This vehicle anti-theft system will lock the wheel when it rotates more than preset cycles whenever the key is in OFF condition. The main component of the circuit is PIC16F73; it’s compatible with PIC16F877A also but here we have used … [Read more...] about Car Anti theft System Project using Microcontroller PIC16f73

What Is Hexa Decimal? Why It Is Used in Microcontrollers?
What is Hexadecimal? Hexadecimal numbers are used in Microcontrollers, Microprocessors, etc. The term Hexa Decimal indicates that Hexa - (six) plus Decimal (ten), i.e. Sixteen. The base 16 number system is called Hexadecimal. At the very launch of computer expansion, it was realized that people had many complexities in managing binary numbers. For this … [Read more...] about What Is Hexa Decimal? Why It Is Used in Microcontrollers?
