In our day-to-day life we frequently use different types of sensors in several applications such as IR sensor used for operating television remote, Passive Infrared sensor used for automatic door opening system of shopping malls and LDR sensor used for outdoor lighting or street lighting system, and so on. In this article we will discuss about a few types of sensors and their applications in brief. But, primarily we must know what is a sensor. … [Read more...]
LM324 Comparator Circuits Working and Applications
The LM324 operational amplifier IC can be worked as a comparator. This IC has 4 independent operational amplifiers on a single chip. This a Low Power Quad Operational Amplifier and it has high stability, bandwidth which was designed to operate from a single power supply over a wide range of voltages. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 3.2 V with quiescent currents about one fifth of those associated with the MC174. … [Read more...]
Know all about Raspberry Pi Board Technology
The Raspberry pi is a single computer board with credit card size, that can be used for many tasks that your computer does, like games, word processing, spreadsheets and also to play HD video. It was established by the Raspberry pi foundation from the UK. It has been ready for public consumption since 2012 with the idea of making a low-cost educational microcomputer for students and children. The main purpose of designing the raspberry pi board is, to encourage learning, experimentation and … [Read more...]
