Project with firmware for Arduino UNO and applications for controlling it via bluetooth.
You can manage your LED on PWM using app which connects to HC-06 module. A slider and fade-in and fade-off buttons are available for control.
- Arduino UNO board
- HC-06 Bluetooth module
- Just a LED
Connect RX and TX only after uploading the firmware and shutdown. Otherwise, you won't be able to upload it.
| Component's pin | Arduino pin |
|---|---|
| HC-06's VCC | 5v |
| HC-06's GND | GND |
| HC-06's RX | TX |
| HC-06's TX | RX |
| LED + | ~11 |
| LED - | GND |
The dimmer project includes a Bluetooth connection and control application for Android. The app was created using AppInventor.
Before proceeding, make sure installation from unknown sources is allowed.
- Download PWM_LED App.apk from Releases.
- Open file from your phone.
- Click "Install" and then "Open" to launch it.
- Make sure that everything is properly connected.
- Open the Bluetooth settings.
- Select HC-06 device in list and connect to it.
- Go to the PWM_LED application.
- Click Search Devices. The HC-06 device will be shown. Click on it to select.
- As soon as the State under the slider says "Connected", you can control the brightness using the slider.
