Control brightness of flexible Neon LED strip using MOSFET driver

The EzloPi smart devices provide automation through simple, customizable use with our open-source EzloPi platform, making daily life easier and improving human-machine interactions.

Before moving into this example, it is very important to know about the device registration, provisioning and converting the ESP32 device into an EzloPi device along with knowledge of Web Flasher, MiOS Mobile Application for Android/iOS and the MiOS Web Application.

This project aims to interface a flexible neon light strip (Red) with the EzloPi device, providing users with convenient control over its brightness. By integrating the Neon light strip with EzloPi, users can remotely adjust brightness levels through the MiOS app’s user-friendly interface, enhancing customization and ambiance in various settings. Leveraging EzloPi's capabilities, the project ensures seamless communication between the device and the Neon light strip, enabling real-time adjustments via Wi-Fi connectivity.

Additionally, the project focuses on simplicity and efficiency, allowing users to effortlessly manage the brightness of the Neon light strip using their smartphones or other connected devices. Overall, this integration offers an innovative solution for personalized lighting control, enhancing user experience and flexibility in a smart home or commercial environments.

Welcome to the project demonstration video section. The following video showcases the key aspects of Control brightness of flexible Neon LED strip using MOSFET driver, providing a visual walkthrough of its implementation.

The following components are required for interfacing with the EzloPi device:

• ESP32 as an EzloPi smart device.
• XY-MOS, high-power dual MOSFET driver module.
• 24 LEDs mini portable lamp.
• 12V power source

The wiring diagram of ESP32 30 pin is represented as follows:

The following connections are made in order to complete the circuit setup:

From ESP32 to the MOSFET driver module:

From MOSFET driver module to LED Strip:

From 12V Power supply to MOSFET driver module:

1. Set up your device/hardware by visiting https://config.ezlopi.com/

2. Log in using the credentials which you just set earlier while signing up.

3. Now, click on the Connect Device button and a pop-up window will appear.

4. Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.

Click Connect

5. If you are new to this and it's your first time configuring, select Create new Device ID. Click on the Configure Wifi button. Enter Wifi SSID and Wifi Password.
6. In the Device Configuration, tab click on PWM.

7. A PWM window will open for inputting the following parameters:

• Set a device name of your choosing. In our case, we set it to Dimmer.
• Set Device subtype to Dimmable Lamp.
• Set OUT GPIO to 5.
• Set frequency by dragging the slider.
• Set the resolution which is 8-bit in our case.
• Set Duty Cycle from its slider.
• Now Click the Apply button.
• After clicking the apply button you can see a table of your setting in the device configuration tab.
• Press the Flash Device button.

8. A window will appear on the bottom right side of the screen displaying “Please press BOOT button while flashing begins.”

9. Hold the BOOT button down until the next window appears on the bottom right side of the screen which says “Installation prepared. Please release the boot button now.”

10. Release the BOOT button from your ESP32 when this pop-up on the bottom right window appears.

11. After some time, a popup will appear saying Device Flashed Successfully! This means that your device has been set up successfully.

You can download the MIOS Android app from the Google Play Store and Apple App Store.

1. After downloading the app, proceed to install the application and open it.

2. Using the MIOS mobile application, create a new Ezlo Cloud account using the sign-up option. If you already have an account, you may proceed to log in.

3. After successfully logging in, you will be able to see the number of controllers connected such as a lamp, fan, or any other device in the MiOS app. Tap on any controller of your desired ID:

4. You will be able to see the status of your controller whether it is online or offline. Access the device dashboard, and tap the device. The following view of the dashboard will appear:

5. After opening the MiOS mobile dashboard, you will be able to see the tile of your connected device. Here as seen above, we have interfaced the LED strip with our EzloPi device and with the MiOS app, we can turn on or off the LED strip and also adjust its brightness.

6. Here, we can see the LED strip is turned on and brightness is set according to our requirement.

1. After configuring the controller with the EzloPi web flasher, head to ezlogic.mios.com

2. Use the same credentials to log in that you used for configuring the controller with the web flasher.

3. After opening the MiOS web dashboard, you will be able to see the tile of your connected device. Here as seen above, we have interfaced the LED strip with our EzloPi device and with the MiOS app, we can turn on or off the LED strip and also adjust its brightness.

3. The LED strip can be controlled easily using the MiOS dashboard after it is successfully interfaced with the EzloPi device. Here, we can see the LED strip is turned on and brightness is set according to our requirement.
