Debug (and control) your Robotic Arm with iOS

This is my work in progress ~50cm Robotic Arm with 6 AXIS Servo motors, an Arduino and a RaspberryPi (for image recognition in phase 2):

Arduino Robotic Arm 6AXIS iOS controlled

While writing the C++ code in Arduino I found I needed a way to send easily and fast commands to Arduino with my iPhone using Bluetooth.

Basically I need to control my robotic arm using an external device instead of running and running again the code on the Arduino board.

For this reason: I’ve attached a BLE board to Arduino and I have created a simple app (completely written in SwiftUI 😍😎) that use BLE connection to connect to Arduino BLE board and send string commands that are parsed and executed.

Commands sended are like:

Arduino/iOS – Bike speedometer tracking using bluetooth

Scope of the project,
add a speedometer on my MTB to store and track the trip using only Bluetooth transmission, send data to iPhone and store to cloud for later data-analysis.

Used components:

  • digital display (controlled by the iOS app). Can show current speed (km/h), total km, current temperature, current humidity.
  • GPS module
  • bluetooth module
  • DHT sensor for temperature and humidity
  • Swift backend
  • mongoDB as database
  • Swift iOS App
