There are a lot of locks out there. There are locks open with a key, with a combination of digits, with various bodily parts, or with a correct geolocation. I decided to make a lock that I have not seen yet. Since I am learning to play piano an idea for this project came quite […]

So far we have seen various devices that are talking, such us cars, dolls etc.This project is also like one of them. you can use it in various projects such us IVS, robots etc. There are various voice recording IC’s. They have different recording time and sampling frequency. Most of the IC’s can record less

This project is used to measure the distance using ultrasonic sensors. The ultrasonic signal passes through the atmosphere to a barrier, which we want to measure the distance. Part of this signal is reflected and travels back to the receiver. The time delay between sending and receiving signals are then determined by distance barriers. The

16×2 LCDs are most commonly used display units in microcontroller based projects. I got much information about LCD, LCD commands, LCD initialization etc from the below link and I hope, it will be very much helpful for beginners. For more Detail: 4 bit interfacing of a 16X2 LCD display to PIC16F877A, Atmega16/32 & MSP430
