Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you, how to make Arduino Projects for beginners. Before gong into the detail of this tutorial first of all I would like to explain you a bit about Arduino. Arduino is an open source micro controller. A lot of help is available online so its user friendly hardware. Most of the students prefer to do work on this device.
Arduino is a low cost high performance device. Due to its cost effectiveness and open source feature it is commonly available in the market these days. An amazing thing about Arduino is that students can take help online with a lot of examples regarding any of the task. There are thousands of Arduino projects are available online f ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today I am going to given elaboration on Introduction to L293D. L 293D is basically a high current dual motor driver/controller Integrated Circuit (IC). It is able to drive load having current up to 1A at the voltage ranging from 4.5V to 36V. Motor driver usually act as current amplifier because they receive a low current signal as an input and provides high current signal at the output.
Motors usually operates on this higher current. L-293D has to builtin H-Bridge driver circuits and is able to control two DC motors at a time in both clockwise and counter clockwise direction. It has two enable pins and they should be kept high in order to control the motor. By changing the p ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you about Introduction to LM1458. Lm 1458 is basically a general purpose dual Operational Amplifier (Op-amp) i.e. it consists of two internal amplifiers. The internal amplifiers has both common power supply as well as common biased network. This is done so that their operation remains dependent on each other.
If the power supply and biasing is not common then they will be totally independent. LM 1458 is a device which is protected from short circuit and it requires no external components for the frequency compensation. LM 1458 is considered to be and ideal amplifier for voltage followers. This is due to its latch-up free operation and high commo ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to PC817. PC-817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
PC 817 has an internal LED and a photo transistor. The photo transistor's base becomes activate when LED throws light on it. The output obtained can be divided into two formats either common emitter or common collector. But the configuration is ...
