In this project, we are going to show you making a simple led flasher circuit using relay and LDR. It is very simple and cheap led flasher circuit, that you can make at home easily.

Here, we are designing a simple light activated switch circuit using LDR. It can be used in security applications like when there is darkness on the LDR, it stops lighting. The main principle of this ...

What is a Relay? Relay is an electro-mechanically operated switch, however other operating principles are also used in relays, such as solid-state relays. A Relay is generally used when it is required ...

Circuit diagram of the switch for the specially abled is shown in Fig. 2. The circuit comprises a bridge rectifier (BR1), 12V voltage regulator 7812 (IC1), dual flip-flop 4027 IC (IC2), 12V ...

Relays are electric switches that use electromagnetism to convert small electrical input into a high-current output. The low voltage electrical inputs activate electromagnets to either form or break ...

Ben's Solid State A/V Switcher. Comes in any color you'd like as long as it's black. As you probably recall we recently had several articles on the Wii laptop which, of course, has Virtual Console ...

I hope you found this article interesting enough to continue reading future columns in this mini-series, in which we will discuss how to build relay-based registers, counters, an arithmetic logic unit ...
