I am trying to control a servo from an esp32 board, however i cannot get the board to accept the platform or something like that. This is my first esphome project so I am far from an expert.
​
This is the code i currently have:

esphome: name: esphome-web-b6eb30 friendly_name: gordijn_controller esp32: board: esp32-c3-devkitm-1 framework: type: arduino # Enable logging logger: # Enable Home Assistant API api: encryption: key: "H2lIqtxaq96p2R8nlsE8VcxspxFbOR5bnN1KvmHccqI=" ota: wifi: ssid: !secret wifi_ssid password: !secret wifi_password use_address: "192.168.0.118" # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: "Esphome-Web-B6Eb30" password: "5UPl39OL16K9" captive_portal: # Example configuration entry servo: - id: servo_1 output: pwm_output # Example output platform # On ESP32, use ledc output output: - platform: espressif32 id: pwm_output pin: D2 frequency: 50 Hz 

And this is the error I am getting:

Platform not found: 'output.espressif32'. 

On some other site I found that the board info should be found on this site: https://registry.platformio.org/platforms/platformio/espressif32/boards. The board I am using is: Ai-Thinker ESP-C3-01M-Kit - met Wi-Fi en Bluetooth 5.0 BLE. I don't know if this is actually correct, any helpl would be appreciated!

Hi everyone,
I've been doing extensive research and i am trying to figure out if the Arduino Nano 33 BLE or ESP-NOW would allow multiple devices use Active RFID or does one of them HAVE to be Central and the others as a receiver?
I want to build a UHF RFID device that isn't restricted to having only one Active and the others as Passive. I want to have the full 100m UHF provides, but I haven't found concrete information whether or not two RFID devices can both be active.
I'm not fond of the idea of having to use 100m and 1m as I want that 100m range to be for both so that they use maximum distance.
Thanks in advance!

Hello Iam looking to make a simple games controller for a boat sim all I am after is forward,backwards and neutral in the middle I have a arduino nano and a potentiometer wired into 5V, GND and AC, I’ve tried to get chat gpt to help with the code and it is useless haha. I do have the joystick.h library installed. Any help would be very much appreciated. Thank you in advance

#include  #include  const byte dataPins [ 7 ] = { D0 , D1 , D2, D3 , D4 , D5 , D6 } ; // Segment data pins: D0 - D6 const byte addrPins [ 2 ] = { D7 , D8} ; // Segment address pins: A0, A1 const byte wrenPins [ ] = {10}; // Write Enable pins (left to right) char t[32]; HPDL1414 hpdl ( dataPins , addrPins , wrenPins , sizeof ( wrenPins ) ) ; void setup ( ) { Serial.begin(9600); Wire.begin(); hpdl.begin ( ) ; hpdl.printOverflow(true); hpdl.clear ( ) ; hpdl.print("*-TIME-*"); delay(3000); } void loop ( ) { hpdl.print("abcd"); delay(250); hpdl.clear(); hpdl.print("1234"); } 

The past few days I've been trying to build a camera setup with the ArduCam Mega 3 MP NoIR and MLX90640 Thermal Camera. I am saving the images on a bare SD Socket. I built it on a breadboard(see appendix, Camera on the right is not attached) for now but I am planning to put it on a PCB in the future.

1. I've tried everything on it's own and it worked without a problem. But now that I have combined everything, the SD Card isn't recognized anymore.

Hello everyone I have a question about arduino in kicad and the copper ring in the connecting the circuit. I am using and Arduino Nano for my project, and i connected the Arduino to elements. My question is, i have top and bottom layer. If i am using the bottom layer and top, do i need to solder the top layer on the front side because its difficult to solder on the front side. My idea is to solder all the pins that i am using on arduino on the bottom layer, because i thing the top layer and bottom layer is connecter with the copper whole so it dosent matter from whot side i am solding I hope you understand my problem Thanks

I am only accepting PayPal F&F.

I'm having an apparently unsolvable problem, I'm making a data acquisition system for an electrochemical cell that has three electrodes, one for reference and two for energy, plus the problem is that I'm using a 16x2 display with the I2c module to show the information of current and aperes (the project is in the beginning and this is just the beta for simple tests) plus the module n show the reading information neither of memory card error nor the memory garbage, I already checked the libraries, physical connections, if everything is working normally and everything is normal, so I ask for help from you in the group to try to find a solution, I will also leave the code here for you to look at, and as the project progresses if you are interested, I can post updates here in the group (I have already tested it the code like the arduino nano and like the 16x2 display without the I2c module gave infinite sending error) now I'm trying like the arduino uno follow the code
#include #include #include LiquidCrystal_I2C lcd(0x27, 16, 2); // Endereço I2C do módulo LCD const int chipSelect = 10; // Pino do chip select do cartão de memória void setup() { lcd.begin(16, 2); lcd.clear(); lcd.print("Sistema de Medicao"); // Inicialização do cartão de memória if (!SD.begin(chipSelect)) { lcd.clear(); lcd.print("Erro no cartao SD"); while (true); } delay(2000); lcd.clear(); } void loop() { float voltage, current; // Leitura das entradas analógicas int sensor1 = analogRead(A0); int sensor2 = analogRead(A1); int sensor3 = analogRead(A2); // Conversão dos valores para tensão e corrente voltage = map(sensor1, 0, 1023, 0, 5000) / 1000.0; // Conversão para volts current = map(sensor2, 0, 1023, 0, 5000) / 1000.0; // Conversão para amperes // Exibição dos valores no LCD lcd.setCursor(0, 0); lcd.print("Tensao: "); lcd.print(voltage); lcd.print("V"); lcd.setCursor(0, 1); lcd.print("Corrente: "); lcd.print(current); lcd.print("A"); delay(1000); // Salvando os valores em um arquivo de texto no cartão de memória File dataFile = SD.open("dados.txt", FILE_WRITE); if (dataFile) { dataFile.print("Tensao: "); dataFile.print(voltage); dataFile.print("V, Corrente: "); dataFile.print(current); dataFile.println("A"); dataFile.close(); } else { lcd.clear(); lcd.print("Erro ao salvar"); while (true); } }

I have a 10g high-tech nano tank, and I've been using the 20" Finnex Stingray 2 on a timer to run a 6-hour photoperiod every day. Plants seem to be doing well.
This light has a switch that can set it to a "moonlight" mode which is basically just blue LEDs. Kinda nice for viewing under certain conditions I guess, but probably about useless for photosynthesis. More importantly, it doesn't have any kind of electronic controls that I can automate, it's just a physical switch.
In the same vein, there is no dimming control anywhere on the unit. My understanding is that LEDs like this would usually dim via pulse width modulation rather than altering voltage or something like that.
Is it actually important to have a gradual change in lighting? Mine has so far just gone from totally off to totally on and vice versa. Is there a known way to get a Finnex Stingray 2 to dim? I'm not opposed to doing some wiring or even work with an arduino or something if it's worth adding this functionality (and possible).

Hello! I hope the title is self explanatory enough because I don't know why it does that myself.
Essentially the motor, driven by a A4988 driver (VRef set correctly for this motor) controlled by an Arduino Nano, vibrates no matter what I do. I've tried multiple motors and drivers and the behaviour is pretty much the same. Oddly enough for a second when I turn off the whole system the motor will run smoothly for a second or so and then stop, when turned back on it'll vibrate and the behaviour will repeat.
I've attached a video with the behaviour mentioned above, I've included the voltage measured with a multimeter measured directly on the A4988 which supply the motor with power
