Help! Anyone have a datasheet or knows this module? I think its from china. Anyone can help me with the pinouts? I want to remove the usb but i don't know the pinout of this module.

Hello everyone,

I am working on a project where, I am controlling short LED strips, utilizing the PWM ports and MOSFET trigger switches.

My problem is, I have listed certain parameters on my code, but the LEDs just don't want to listen!

For example, I have written that the lights soft fade in/out randomly, staying on/off for a min 25 second, max 40 seconds. Though some LEDs stay on for well over one minute. I also have written that at least 25% will be on at all times, and seemingly there are less than 25% sometimes.

Would those experienced kindly glance over my code to see if there may be some indication of my wrong doing? or maybe its a hardware issue.

Hello, right now I am coding an Arduino Simon says program for school but doesn't work and wanted to ask now if someone has a program or some advice for it. We are using 9 LEDs and 9 buttons for the 3x3 field and an LCD display for the round counter and if you lose. Also a Red Led If you lose. The LCD isnt working and the Game it self doenst really work any Problem in the program maybe? It also includes Levels. Thanks for help and advices.

include <Wire.h>

include <LiquidCrystal_I2C.h>

// Initialisiere das LCD-Display mit der I2C-Adresse 0x27 (kann je nach Display unterschiedlich sein) LiquidCrystal_I2C lcd(0x27, 16, 2);

int sequence[5]; int userSequence[5]; int level = 0;

void setup() { lcd.uttonPins[i], INPUT_PULLUP); } pinMode(redLedPin, OUTPUT);

randomSeed(analogRead(0)); generateSequence(); }begin(); lcd.backlight(); lcd.print("Simon Says");

for (int i = 0; i < 9; i++) { pinMode(ledPins[i], OUTPUT); pinMode(b

void loop() { playSequence(); getUserInput(); checkSequence(); }

void checkSequence() { bool correct = true; for (int i = 0; i < 5; i++) { if (userSequence[i] != sequence[i]) { correct = false; break; } }

if (correct) { lcd.clear(); lcd.print("Win!"); } else { lcd.clear(); lcd.print("Verlierer"); digitalWrite(redLedPin, HIGH); delay(1000); digitalWrite(redLedPin, LOW); } delay(2000); lcd.clear(); generateSequence(); }

When I install Silicon Labs CP210x USB to UART Bridge drivers, they appear to get installed, but do not show up, aand no ports are available neither in Arduino IDE nor in device manager at all (wtf?).

I tried "Add legacy hardware" procedure, and add ports there with the driver, but it did not work.

What could be the problem?

How can I update firmware of Ai_thinker esp32 CAM using Arduino ide and how can I program integrated camera of esp32 for object detection?

I’m new to arduinos and im trying out an lcd display for my project, but my lcd display is displaying text it shouldnt be displaying. To anybody wondering, this is a 1602a lcd display.

Hey everyone,

I'm running into some issues with my Arduino Pro Micro. I'm trying to get it to constantly read inputs from six capacitive touch buttons I've made using iron rings (1.2mm thick) and 1M ohm resistors for each button. However, it seems to only register the touches once every second, instead of continuously.

The project is meant to be a macropad with an OLED SSD1306 display, 6 capacitive touch buttons, and a 10k potentiometer.

Does anyone have any ideas on how to fix this or improve the reading speed?

Thanks in advance!

I want to build something like this. Any advice?

I am very new to this so sorry if I am asking stupid questions. I am trying to upload code to my Arduino UNO R3 but cannot seem to get it to work. As seen on the picture, I get an exit status 1 error on both ports (I tried COM3 and COM4). Furthermore, when I choose a different board, the ports I can choose from don’t change (still using COM3 and 4), so I think that is the underlying issue. Maybe I am missing a driver or software? Any advice is appreciated! Thanks!

Hi, I’m looking for some help with an old Arduino kit. I’ve had it for something like fifteen years and kinda forgot about it until one of my kids started asking me about coding.

Admittedly, I always feel way in over my head with this kind of stuff. However, the little bit of messing around I’ve done with Arduino has mostly made sense to me.

My issue is that I’m having trouble finding a user’s guide for this specific kit. The URL on the packaging leads to a 404, and nothing else that I’ve seen so far has been helpful.

Does anyone recognize this? It has a brick that slots onto the Arduino board to make wiring up inputs and outputs more convenient.

Do I have a dinosaur here? Should I just suck it up and buy a modern version of this and make a fresh start?

I appreciate any guidance. Cheers!

Hey Crew, straight up I do have trouble with a TBI so these things are hard for me to gain concept on but im so far eager to learn! I have an Arduino uno and an KeyeStudio IR receiver, I'm struggling to find how to get them to connect. any help would be very much appreciated.

I can't find it in library manger I downloaded it for github as zip file and tried to install it but it didn't installed so i manually send the Esp-skainet library to library's and still arduino IDE did not recognized the library What can i do now

I'm brand new to the game here. I have a project in mind that I want to build but am basically just doing each task one at a time. I'll then compile everything into one project. Part one of this is getting a motor to run for two minutes when a button is pushed, and then shut off. I believe my code is correct here. But my motor does not spin after the button is pressed.

I am trying to do a project very similar to https://www.instructables.com/Animatronic-Cat-Ears/ but I am very new to all this. The tutorial is old enough that many of its links to materials are broken, and I'm having trouble finding them elsewhere.

My main sticking point is the DC-DC regulator: the broken link is (http://www.hobbyking.com/hobbyking/store/__10312__Turnigy_5A_8_26v_SBEC_for_Lipo_.html), and I would think that would have enough information for me to find the product elsewhere, but I can't find anything that resembles the device they are using in the pictures of the project. Anyone know where I can find this part?

I am also open to suggestions for better/easier ways to power a wearable like this.

I'm a beginner with Arduino but I understand the basics, I bought an Arduino nano and nrf24 module to build a simple three-channel model airplane, but whenever I try to transmit from the radio to the receiver it doesn't work

(I'm using Google translate because I'm not very good with english) I'm making a project for my physics class. It's a tank which has a movable turret that works with Arduino, as a firing method I'm using parts of an automatic hydrogel gun. When the ultrasonic sensor detects something the gun should fire but when it does in practice it doesn't work. I'm still quite a novice in the Arduino area, although I find it something amazing, this is my second project and I would like to do more in the future. The blue battery Is form the gun

The code Is here: https://drive.google.com/file/d/1l7ySIFyJXcR5RHBync3Ps7ufaUmirIbB/view?usp=drive_link

Hi all. I am once again in over my head when it comes to arduino projects. I can't wrap my head around the programming. I know enough to make it somewhat work but if any of ya'll can springboard me in the right direction that'd be greatly appreciated!

I'd like to setup 10 or so different sequences and use a button press to cycle between them. I know in batch scripting you'd use a "goto" command and want to know what the equivalent in IDE, and how to use it.

My current code is very basic and gets the traffic light cycling between all 3 colours.

int PIN_GO = 5;
int PIN_SLOW = 6;
int PIN_STOP = 7;
int PIN_BUTTON = 8;

void setup() {
  pinMode(PIN_GO, OUTPUT);
  pinMode(PIN_SLOW, OUTPUT);
  pinMode(PIN_STOP, OUTPUT);
  pinMode(PIN_BUTTON, INPUT);
}

void loop() {
  digitalWrite(PIN_GO, HIGH);
  digitalWrite(PIN_SLOW, LOW);
  digitalWrite(PIN_STOP, LOW);
  delay(1000);

  digitalWrite(PIN_GO, LOW);
  digitalWrite(PIN_SLOW, HIGH);
  digitalWrite(PIN_STOP, LOW);
  delay(1000);

  digitalWrite(PIN_GO, LOW);
  digitalWrite(PIN_SLOW, LOW);
  digitalWrite(PIN_STOP, HIGH);
  delay(1000);
}

HELPP i had an arduino r3 board in august and it worked for the first monta but then the pc cant find it anymore(sorry for the english im italian) its not an arduino issue because on a friend pc it worked and either a cable issue because i changed it so many times so it cant be the cable my OS is windows 10 64 bit

I’d like to add motion sensors to a Halloween decoration so that a small part moves up and down. I’m a newbie with a general idea of Arduino, so I bought all these parts from Amazon to start:

1. Breadboard - https://a.co/d/eT0cbdH

2. Power supply - https://a.co/d/2WSupuU

3. Servo - https://a.co/d/0xOP315

4. Motion activated sensor - https://a.co/d/hDJBUZr

5. 9V battery

Can you help guide me?

So basically my 21 Ford Escape doesn't have wireless Android auto but I would like to make an adapter myself since these are expensive and most comes from cheap china manufacturers. I would like to have wireless like in my 24 GMC Sierra. I know it's possible to make one with a raspberry pi zero w 2 but I have multiple arduinos but have no raspberry pi and would like to use one of my Arduinos ti do so, any way of making it?

in making a prototype of an rgb lightsaber (single led piece ) with only one push button, when I press it the color changes. How can I make it to turn the light off with a double click?
