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.

Circuit Diagram Below is the circuit schema of the car control system, including the Arduino, L298N motor driver, and HC-SR04 ultrasonic sensor. Note: The pin numbers in the diagram may differ from ...

Connect Rx (pin 2) directly to TXD of the HC-05. Since pin 3 cannot be connected to RXD (as the HC-05 expects 3.3V logic levels), a potential divider with 1k and 2k resistors is used to connect RXD to ...

I am using the l2C Protocol for Communication between the two Arduinos. For Arduino 1 (Master Arduino): The Temperature and Humidity Sensor is connected to pin 9. The Main Gate Servo, Tank Servo and ...

The watch is built around an Arduino Pro Mini, a scavenged Nokia LCD, and a BlueSMiRF Gold. The Bluetooth connects to a Nokia N900 with a little Bluetooth client app [Ahmet] wrote.
