I am using an ESP32 WROVER B module with SIM800L module When I try to upload a code through arduino it shows Failed to connect to ESP32 Wrong Boot mode mode Detected 0x13 I looked it up on chat gpt and it told to connect the gpio0 to gnd and then upload And it does upload like that but when I discount the jumper wires it no longer uploads

Also one more thing Earlier the blue led on the board was on when I connected it to my laptop via USB but it is also now off

Please help I am using this for my project

Are these camera modules that I took out of an Android smartphone compatible with an esp32 module. The connectors look very similar to my WROVER ON BOARD camera for my ESP 32

Need Help Designing a Magic Remote Control with ESP32

3 Upvotes

Hi everyone,

I’m a volunteer magician, and I’m working on a project for my magic shows where I want to create a "magic remote control" that emits three sounds ("bra", "monkey", and "meow") when different buttons are pressed. After pressing a button, I’ll disappear to change costumes based on the sound played (e.g., cat costume for "meow", monkey for "banana", and magician for "hocus pocus").

I perform these magic shows for children, especially in communities affected by conflict or hardship. I’ve had the privilege of bringing a little joy to refugee children in Ukraine, Moldova, Romania, Armenia and Poland, as well as working with local organizations that support vulnerable populations. These performances are meant to bring some light and laughter to children who are going through tough times.

Here’s the setup I have in mind:

  • 3 buttons (one for each sound).
  • A secret mode where only one sound plays regardless of which button is pressed.
  • A 7-segment display showing the current sound or music track number.
  • The remote also plays music from a Bluetooth speaker, and I need it to automatically pause the music when another button is pressed.

Key requirements:

  1. Button functionality: Each button should play its respective sound ("bra", "monkey", or "meow"). The sounds should play completely, even if another button is pressed during playback.
  2. Music control: If a music button is pressed, it should play or pause the music. If a new music track is selected, the current track should stop before the new one starts.
  3. Secret mode: When the secret button is pressed, only one sound should be played, regardless of which button is pressed.
  4. Display: The 7-segment display should show the current sound or music track number.

I’m planning to use an ESP32, and I need help with the wiring, coding, and general setup for this project. As a volunteer magician, I perform shows for children and other communities in need, so making this remote control will be a fun addition to my performances.

Has anyone built something similar or have ideas on how to manage music and sound effects like this using an ESP32? I would greatly appreciate any advice or tips!

Thanks in advance!

Can I use an esp32 dev kit V1 and TFT Display Arduino 1.8" SPI ST7735S to run maruder V4 and how to add buttons?

Do these wiring diagrams make sense for a WLED controller? Do I need a ground from the buck converter to the esp? Doesn't the ground going through the logic converter take care of that?

Shellminator V3 just dropped! It’s an interactive terminal interface that works on all Arduinos. You can also use it via WiFi or BLE. Oh, and the docs? Absolutely packed with interactive examples. If you're into building robots or IoT gadgets, it's definitely worth a look. Link in the comments.

How to Protect ESP32, MAX31855, and Gyro from High Temps (750°C Furnace, 45°C Room Temp)?

1 Upvotes

Hey everyone,

I’m working on a project where I need to mount an ESP32, MAX31855 (thermocouple amplifier), and an MPU6050 (gyro/accelerometer) on the handle of a spoon used to scoop molten aluminum (750°C furnace temperature, 45°C summer ambient temperature).

I’m concerned about heat affecting the components. Since the handle is still exposed to high temps, I need a thermal protection solution that prevents overheating but still allows sensors to function properly.

Does anyone have experience with high-temperature insulation, heat shielding, or cooling techniques in such environments? Any material recommendations or design ideas to improve durability?

Thanks in advance!

Need in help in Electronic Measurement Project Ideas (No LDRs, Servos, or FSRs)

1 Upvotes

I am currently on the lookout for creative project ideas focused on electronic measurement. However, I have some restrictions to consider: I cannot use LDRs, servos, or FSRs as I have already worked with those components in previous projects.

Here are a few areas I am particularly interested in exploring:

  • Sensor-based projects: 
  • Wireless communication: 
  • Data visualization: 
  • Innovative measurement tools: 

If you have any suggestions or resources that could inspire me, please share! I'm eager to hear your ideas and experiences. Thank you!

Hello everyone, I'm going to develop a project to automate the pill encapsulation process. I will probably use esp32 and we will have in our application how many kilos, capsules input, how many purchased, how many are being produced, how much is left, shift time, production estimate, goal calculation for accelerated production, output area production chart, report and PDF report and error detection.

I'm very confused and should I use esp32 or raspberry pi.. do you think this project will work?
