Arduino : Reading Sensor Data Using Bluetooth: This tutorial demonstrates a simple way to make use of bluetooth for reading data in arduino projects. The aim of this tutorial is to gather sensor data from a simple temperature sensor and transfer it to the PC using bluetooth communication.

To identify if an Arduino has Bluetooth built in, look for the u-blox chip and antenna on the top of the Arduino board. The u-blox chip allows the Arduino to act as a client or host device with support for both BLE (Bluetooth Low Energy) and regular Bluetooth.

Apr 14, 2023 · In this tutorial, we will show you how to get started on incorporating Bluetooth into your electronics projects. This project uses a SparkFun Thing Plus ESP32 Wroom USB-C to display data from a Triple Axis Accelerometer over Bluetooth.

As I promised, I uploaded my next instructable. This one is going to cover Bluetooth and Ultrasonic sensor(HC-SR04). Why those two. I made an RC 2 wheel car for my school project. It' controlled with a free app via bluetooth. To make it "half robot", it has distance sensor, that mesures distance.

Sep 4, 2024 · Central devices take on the role of initiating connections to peripheral devices. For example, your smartphone is often a central device when connecting to Bluetooth® LE peripherals like fitness trackers, smart sensors or an Arduino board.
