Yes, the HUSKYLENS can recognize objects beyond the 20 built-in categories using its learning mode. The steps to achieve this depend on what type of object recognition you want (e.g., color, shape, or a specific custom object). Here's how you can approach it:
1. Using the Learning Mode
HUSKYLENS includes a "Learning" mode that allows you to teach it to recognize custom objects. Here's how to use it:
Switch to the appropriate algorithm mode (e.g., "Object Recognition" or "Custom Object Recognition").Point the HUSKYLENS camera at the object you want it to learn.Press the "Learn" button (either on the device itself or through your connected controller/software interface).Move the object or adjust its angle to ensure the HUSKYLENS captures various perspectives.The HUSKYLENS will store the learned object in its memory and recognize it in subsequent views.2. Optimizing Recognition
To improve the recognition of custom objects:
Ensure good lighting conditions and minimal background noise.Provide multiple angles and distances during the learning process.If the object has distinct patterns or colors, use the "Color Recognition" or "Shape Recognition" modes for enhanced accuracy.3. Saving and Reloading Custom Models
The HUSKYLENS can save learned objects in its memory, but it will lose them if powered off unless you save the data externally (e.g., using an Arduino, Raspberry Pi, or similar microcontroller).
4. Advanced Options
If the built-in recognition capabilities are not sufficient, consider integrating HUSKYLENS with a microcontroller or computer for custom-trained AI models. You can:
Use HUSKYLENS for capturing object data.Process the data externally with platforms like TensorFlow Lite or OpenCV.Reintegrate the custom recognition model with your HUSKYLENS-enabled system.Let me know if you'd like more specific guidance based on your project setup!

If you're having trouble connecting your DFR1140 ESP32 UE IoT (a version of the ESP32 board) to the Arduino IDE, there are several potential issues to check. Here’s a troubleshooting guide to help resolve the problem:
Step-by-Step Troubleshooting:
Install ESP32 Board Support in Arduino IDE:
Open the Arduino IDE.Go to File > Preferences.In the Additional Boards Manager URLs field, Then, go to Tools > Board > Boards Manager, search for ESP32 and click Install.Select the Correct Board and Port:
After installing the ESP32 package, go to Tools > Board and select your specific ESP32 model (e.g., "ESP32 Dev Module").Also, ensure the correct Port is selected under Tools > Port (usually shown as the COM port or device name your ESP32 is connected to).Check USB Cable and Port:
Ensure that the USB cable you're using is data-capable (some cables are only for charging).Try a different USB port on your computer and make sure the cable is securely connected to both the ESP32 and your computer.Install Drivers for ESP32:
Sometimes, ESP32 boards require drivers that may not be installed automatically. You may need to install the CP210x or CH340 USB-to-serial drivers, depending on the specific USB chip on your board. These drivers can usually be found on the manufacturer's website or through Espressif's documentation.Reset or Boot Mode:
Try resetting the ESP32 or putting it into bootloader mode manually. To do this:Press and hold the Boot button on the ESP32 while pressing and releasing the EN (Reset) button. Then release the Boot button. This can help the board enter the correct mode for programming.Check the Arduino IDE Console for Errors:

The issue of "too many disturber detection" in lightning sensors, such as the AS3935 or similar models, is commonly associated with external interference that causes false lightning readings. This happens when nearby electronics, power lines, or other high-energy sources introduce noise or electromagnetic disturbances, which the sensor may mistake for actual lightning strikes. This is why you might see a "disturber" status instead of a normal "lightning detected" reading.
To mitigate this, you can adjust the sensor's sensitivity settings. For instance, switching between "indoor" or "outdoor" modes, or increasing the noise threshold can help filter out low-level disturbances. It's also helpful to ensure the sensor is placed far from potential sources of interference like large electrical systems or broadcasting equipment【67†source】【68†source】.
In some cases, resetting the sensor or its configuration can help resolve temporary interference, allowing the system to return to normal operation【69†source】. If the problem persists, you might need to further shield the sensor or experiment with different placements to avoid constant disturbances.

If your DFR0946 Buck-Boost converter is entering protection mode during startup, this issue could be linked to several factors, including inrush current or improper component settings. The DFR0946 is a versatile converter that handles both buck and boost functions, allowing the output to remain stable even if the input voltage is above or below the desired level

.
A common issue in such power supplies is the output capacitor's inrush current during startup, especially if it's too large. When the capacitor charges, it can cause a high peak current through the inductor, which may trigger the protection mechanism if it exceeds the converter's limits
EE Power
. To mitigate this, ensure that the output capacitance is properly sized for the converter's specifications, balancing good filtering with manageable inrush current

.
Additionally, check your input and output voltage settings and ensure that they are within the acceptable range for the converter. A mismatch in voltage settings, especially under load or at startup, can cause the module to enter protection mode
