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.

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 ...

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 ...

I programmed this project as my final project for EECS183! For this project, I decided to program a reimagined version of the classic arcade game Joust! To play you need to use an Arduino Mega, two ...

You can access BT SPP in your Arduino code, treat it as a serial device and connect to your Edison project via Android phone with BT SPP App. This means you can control your Edison projects ...

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 ...

Features of the LightBlue Bean+ Bluetooth Arduino Micro-Controller include : – 3-axis accelerometer – Temperature sensor – RGB LED – 3.7V 600mAh LiPo battery – ATmega 328p @ 8 MHz clock ...

The $22 kit includes an Arduino-BLE board and 6-pin header that should be fairly broadly applicable for building Arduino-based hardware that can communicate with iOS devices.
