Working of the Basic 5V Relay Circuit. In the above circuit, 5V relay is powered by a 9V battery. An ON/OFF switch is added for the switching purpose of the relay. At the initial condition when switch ...

5. Build your own Mars Rover Robot using Arduino: This cool looking Arduino Project presents the construction of an Arduino-based Mars rover, emphasizing design, components, and assembly.It highlights ...

It works in two different modes, Normally Open (NO) and Normally Closed (NC). in our project, we will use it in Normally Open mode which means when the relay is switched off the circuit will be broken ...

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.

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. This sketch will make an interrupt at Alarm set ...

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 ...

Abstract: This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect ...
