hi i want to light up a 12 volt LED strip and need to use a uln 2003 a and a 6volt relay and a capacitive sensor to control the light. i.e. when i once touch it it switches on, and when i touch it ...

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 ...

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.

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

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 ...

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 ...

Controlling Linear Actuator using Arduino The parts required for the project setup are Arduino UNO, progressive automation PA-14-6-50, 12V 5A power supply, female power plug, small flat head ...

The device operates on a 5V DC supply, with capacitors C1 and C2 filtering any ripples. The Arduino Nano serves as the controller. The PIR motion sensor detects human movement and transmits data to ...
