Lets take a simple example where we will be turning on an AC lamp by using a relay switch. In this relay circuit we use a push button to trigger a 5V relay, which in turn, complete the second circuit ...

This arduino UNO project introduces a Sun-tracking system project using an Arduino Uno, a servo motor, and LDRs to optimize solar panel efficiency. Hardware components, circuit connections, and ...

Commands are sent via Bluetooth to Arduino Uno. So you need not get up to switch on or switch off the device while watching a movie or doing some work. Home automation circuit and working The home ...

A password-based circuit breaker or PBCB is an electrical switch operated through a user-defined password, providing a secure and controlled means of activating or deactivating an electronic circuit.

I designed this relay circuit to function as a DPDT toggle which is controlled by a momentary switch. I strive to keep my circuits simple with little or no integration (555’s, transistors, etc). The ...

So here is the simplest way to control most of your home appliances, without getting up and moving to the switchboard, through Arduino. How to Automate Your Home Appliances using Arduino? Now let’s ...

Circuit and Working The circuit diagram of the automated washroom light is shown in Fig. 2. It is built around Arduino Uno (Borad1), BC547 transistor (T1), infrared (IR) sensor modules (Module1 and ...
