Features: 1. You can enter password through […]

As regular readers may already remember, my second-generation (2013 “FHD”) Nexus 7 tablet has been a repeated topic in past blog posts. And in most-to-all of them, I grumble about the fact that it’s still stuck on Android v4.4.2 (which dates from early December 2013), presumably due to Verizon constraints (it’s a cellular-plus-Wi-Fi model), and […]

AVR Microcontroller based Temperature Controller, it uses LM35 Temperature Sensor for measurement of temperature and 16×2 LCD is used to display temperature set point, Heater Status and current temperature, It controls temperature by turning on and off of the heater using relay. This project is very useful for controlling of temperature, It can be used […]

The LTC7851 is a quad output multiphase synchronous step-down DC/DC controller with accurate current sharing between phases and differential output voltage sensing. This controller works in conjunction with external power train devices such as DrMOS and power blocks as well as discrete N-channel MOSFETs and associated gate drivers, enabling flexible design configurations. Up to 8 […]

Bluetooth based home automation, project allows you to control electrical appliances using your android mobile phone. It consists of ATmega8 microcontroller, HC-06 Bluetooth module, Relays. There are many Home Automation Systems available in our market. Most of these are simple home appliances controlling systems like DTMF controlled home Appliances, IR Remote based home appliances controlling, RF based […]

Abstract: This article is how-to guide, intended as a quick learning aid for engineers considering using the MAX6954 to drive 14-segment monocolor LEDs. The MAX6954 is a versatile display driver, capable of controlling a mix of discrete, 7-segment, 14-segment, and 16-segment LED displays through a serial interface. This application note shows a typical application and configuration […]

This AVR microcontroller based project demonstrates Finger print based access control / security system, in this project we have provided all required data, PCB, Code, Circuit Diagram, Proteus Simulation. This project operates a relay based on valid finger detection. It is provided with 6-Keys for Addition, Deletion of Finger Print. It uses standard SM-630 Fingerprint […]

How about a cheap serial terminal for less than a fiver all-in? In a previous blog entry I’ve been working on more developments for the increasingly powerful home control system using an Arduino as a kind of universal I2c peripheral to the ESP8266. The reason for that is just the vast range of driver software […]

Bank token number display project is build using ATmega8 Microcontroller and ULN2003 for driving large LED display, PCB layout, Circuit diagram are self explanatory. It is capable to display three digits, its simple project using microcontroller. Token issue systems are ideal for banks, airports, public dealing offices, hospitals,doctor’s clinics, restaurants and other such places where […]
