Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

Temperature Controlled Fan using Arduino Code Explanation The complete Arduino code for Temperature controlled fan is given at the bottom of this page. You can also get the code from CircuitDigest ...

When the button is pressed the Arduino board will put pin 2 in HIGH state, meaning 5V on pin 2. This voltage is used to drive the transistor that will switch ON the relay and the load (in our case the ...

Features: Hardware components: Arduino, relay module, jumper wires, and external power source Code: Arduino code for controlling the relay based on sensor input or a manual switch Applications: Home ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Arduino program to handle relays and control them using switches. Single pair of relay and switch are configured in single line. Buttons has debouncing and support for mono- and bi-stable switches.

All we need to do is swipe or place an authorized RFID card in front of the RFID reader. Here, Arduino handles data processing activities to decide whether the RFID card is valid or not. If the card ...

In this proposed project, the quantity of liquid dispensed depends on the delay time for each digital output pin of the Arduino, which gets added through Arduino programming. Here we have used five ...
