In this tutorial, we are going to look at switch mode power supplies. A switch mode power supply (SMPS) is basically an electronic power supply that efficiently converts electrical power. It transforms power coming from the main source and gives it to the load, like a transformer. It converts current and voltage characteristics. The transistor … Read more
In this tutorial, we will look at wireless sensor networks. Wireless sensor networks are a group of specialized devices or sensors that we can use to monitor different environmental conditions and collect and organize that data at a certain central location. It detects and measures a number of physical conditions, such as humidity, temperature, sound, … Read more
A voice recognition system involves biometric technology. This technology is getting very popular nowadays for security purposes and for electronics projects among engineering students. It can easily identify individuals on the basis of their voice, and the chances of theft and fraud are reduced. Other methods of biometric identification are iris/eye scans, fingerprints, face scans, … Read more

I2C (Inter-Integrated Circuit) is a serial communication protocol that allows multiple devices to be connected to a single bus. It is commonly used in embedded systems and other applications where a small number of devices need to communicate with each other. Data transmission between digital devices can mainly occur in two ways, parallel or serial … Read more
In this tutorial, we will discuss the analog to digital converter. An analog to digital converter (ADC), as its name indicates, is an electronic device that converts continuous time-varying analog signals into discrete-time digital signals so that they can easily be read by the digital devices. It has many applications in electronics projects. ADC converts … Read more
