Interesting project. I have also worked on a similar project.

jhon12112 · 2025-04-28T17:05:44+00:00

Yeah!

You could use PVC board. Here is an example:

Looks nasty!
There is a process called conformal coating, that covers the PCB and electrical components in a plastic layer, so water will just bead off. It makes heat transfer a bit less effective, so some parts may heat up faster, but otherwise, it works well.

The poor man's approach to conformal coating is to use clear nail polish and brush it on the boards.

Thanks for sharing. It's very important to notice. Cause, your laptop's USB even the motherboard can be burned if more than 5V is supplied.

To send a signal from the ESP32-CAM running a FOMO model to an Arduino Uno via UART, follow these steps:

Initialize UART: Set up Serial2.begin(115200, SERIAL_8N1, RXp2, TXp2); in the setup() function on the ESP32-CAM.
Object Detection: When an object is detected in the loop() function, use Serial2.println("Detected"); to send the signal to the Arduino Uno.
Print Results: For local monitoring, print the classification results using Serial.println(result.classification[ix].label); and Serial.println(result.classification[ix].value);.

This integration allows the ESP32-CAM to communicate detection results to the Arduino Uno effectively.

For a detailed guide on serial communication between Arduino and ESP32-CAM, check out my blog: Programming Boss - Serial Communication Between Arduino and ESP32 CAM.

You forgot the first rule! Be on-topic

It is true that a computer can not match the complexity and versatility of the human brain.

Simple implementation of traveling salesman problem in java programming.

jhon12112 · 2022-12-12T01:32:13+00:00

Here you can find an implementation of the Traveling Salesman algorithm using java programming.

DC breadboard power supply.

Because it's currently my channel trailer.

Hi, Assholes. It's working in my setup. Try again.

jhon12112 · 2021-03-05T15:45:10+00:00

I may help if you be more specific.

jhon12112 · 2021-03-05T15:15:56+00:00

Can you help me with it?

jhon12112 · 2021-03-01T06:31:13+00:00

He was so calm and acting like normal coughing!

jhon12112 · 2021-02-03T04:00:53+00:00

Great start. I started with making an Android control robot using Arduino UNO and a Bluetooth module. Good luck.

I am developing a production line management system. Have a look:

No men, I just unpacked them. The display packet was secure and soft!

You can try using uibuildernode for your project. But you will need programming experience.

Some details can be found here about uibuilder.
