three phase surge protector circuit

Three are two types of electrical/electronics appliances based on the main supply it requires. Generally, heavy electrical equipment requires a three-phase main supply for working. Three-phase mains supply has three different phases each are placed at 1200 angle with each other. In this post, you will learn how to design a three-phase power surge protector circuit using timer IC 555. A three-phase electrical appliance is expensive and requires all phase supplies, if voltage fluctuates or fails in any phase operation of the appliance may malfunction or become dead. In order…

We are getting about how to make the digital clocks more accurate and precise even at varying parameters like temperature and humidity. Generally, in the market, if we go for buying the RTC module we will find the DS1307 module more simply. As DS1307 module is more prone to external temperature variation because it uses an external crystal oscillator circuit as a result the accuracy of the timekeeping changes. While designing a LED board for my college kec.edu.np, I suffered from a time accuracy problem. After a few days, time…

diy 5x3 matrix keypad for arduino

In this tutorial we are going to design a customized DIY 5×3 matrix keypad for arduino using tactile switch and small signal diode 1N4148. Many microcomputer/ Arduino system designs require some type of a keypad as an input device. Some time we required customized key for our own project rather then conventional available matrix keypad (4×4 or 4×3) in market. What if we require the key for other operation like left, right, up, down and ok operation. The outlook of the project may not be sophisticated if we had used…
