iOS controls for Arduino

A clean control panel for Bluetooth projects

Build a board in the app, assign channels, then read the controls in Arduino code. Buttons, joysticks, sliders, toggles, D-Pads, displays, labels, indicators, gauges, console messages, and alerts all use the same simple loop.

App board + BLE module

Build the first board Wire BLE, upload Hello World, and tap a real app button. Pick components See what each control sends and the Arduino code that reads it. Use the API Call readSerial(), read controls, then update displays and gauges. Check the data format Use the message builder and table when you need the exact bytes.

Build the board. Read the controls. Send the readouts.

Bluetooth Serial Connect gives an Arduino project a custom iPhone or iPad control panel. Pick components in the app, read their channels in your sketch, and update app readouts with one-line API calls.

The whole system in four moves

Place components in the app
Buttons, joysticks, sliders, toggles, D-Pads, displays, labels, indicators, and gauges all get a channel number.
Connect through BLE serial
An HM-10 style BLE module advertises to iOS and forwards the app's bytes to your microcontroller over UART.
Call readSerial() in loop()
The library parses each line and refreshes control state. Your sketch reads methods like wasButtonPressed(), getSlider(), and isToggleOn().
Send status back
Use setDisplay(), setLabel(), setIndicator(), setGauge(), and sendAlert() to keep the board live.

void loop() {
  serialConnect.readSerial();

  if (serialConnect.wasButtonPressed(0)) {
    serialConnect.sendAlert("Button 0 pressed");
  }

  if (serialConnect.isSliderUpdated(0)) {
    analogWrite(9, (int)serialConnect.getSlider(0));
  }

  if (serialConnect.wasToggleUpdated(0)) {
    digitalWrite(2, serialConnect.isToggleOn(0) ? HIGH : LOW);
  }

  serialConnect.setGauge(analogRead(A0), 0);
}
