Where's the source code??

Te amo

Here's the code. just make sure you replace 123456789 with your RIFD's correct UID. #include <SPI.h> #include <MFRC522.h> #include <Servo.h> #define RST_PIN 9 #define SS_PIN 10 MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance Servo doorServo; // Create a Servo instance // Define the RFID tag UID you want to allow access const String authorizedUID = "123456789"; // Change this to your RFID tag's UID void setup() { Serial.begin(9600); // Initialize serial communications SPI.begin(); // Init SPI bus mfrc522.PCD_Init(); // Init MFRC522 doorServo.attach(3); // Attach servo on pin 3 // Start with door locked doorServo.write(0); // Change this angle to the locked position } void loop() { // Look for new RFID cards if ( ! mfrc522.PICC_IsNewCardPresent()) { return; } // Select one of the cards if ( ! mfrc522.PICC_ReadCardSerial()) { return; } // Read UID of the card String readUID = ""; for (byte i = 0; i < mfrc522.uid.size; i++) { readUID += String(mfrc522.uid.uidByte[i] < 0x10 ? "0" : ""); readUID += String(mfrc522.uid.uidByte[i], HEX); } readUID.toUpperCase(); // Convert UID to uppercase Serial.println("RFID Tag UID: " + readUID); // Check if UID is authorized if (readUID == authorizedUID) { unlockDoor(); } else { lockDoor(); } // Halt PICC mfrc522.PICC_HaltA(); // Stop encryption on PCD mfrc522.PCD_StopCrypto1(); } void unlockDoor() { Serial.println("Access Granted.

pleaase

code plis

Cool

realy fast

the motor won't move how does it move

Share the code make google drive file

Would be great if you showed how this was wired up.

YUNG CODE!!!!!!

@COMMONCODING i tried to insert the code into my arduino and it says 'interruptSetup' was not declared in this scope This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Does anyone have the code?

bgs

could you please tell me the specifications of the resistors?

Good day 👋 How to setup code for my 4pin led rgb module in which the led fast changing colors blinks in line with the speed of music beat or noise and automatically turn to super slow changing color mode when there is no music or noise detected on the surroundings?

Try to make The exception to this design... for example, when one of the buttons is pressed first, the other buttons will not be active or functional until the specified time.

hello! great video but i'd like to know if this works with arduino uno? thanks in advance

can you post the code?

How I can calibrated it and cinvert value into angle value

guys if you're on chromebook, press ctrl m to open the output

your welcome folks void setup() { pinMode(2, OUTPUT); pinMode(12, OUTPUT); Serial.begin(9600); } void loop() { if(digitalRead(12) == HIGH) { Serial.println("HIGH"); digitalWrite(2, HIGH); } else { Serial.println("LOW"); digitalWrite(2, LOW); } delay(500); }

how about to fix a rubber membrain buttons. like in a tv remote?

thanks man

Simple but still a great little project. Imagine attaching a motor you want instead of an LED. But you have to protect the pwm port with a resistor with a high ohmic value, mosfet and motor powered with an 'external power supply (of course). I have not had time to source this handful of components but I will have to make it and hopefully soon. But how can I adjust the duty cycle so that I have a 'max amplitude and max speed?

How to connect it with electrocity?

Hello, first of all, the project is very nice. I tried to do it but couldn't get it to work. The correct tones come out, but when the resistance is touched, they come out. I couldn't find what I did wrong. I would be happy if you help.

can we watch its data ove internet

Lol

Thanks it helps a lot

Hey! Just remember that that most flex sensors are designed to flex away from the resistive strip side. (in this case the striped side) For best results and lifecycle of the flex sensor anyway. :) Also we just dropped our next gen Flex Sensors, the "SpectraFlex". Check them out!

que buen video bro me pajie

Thank you... ❤

Thanks for the learning

Your code is not good and can broke the LCD or show errors because the LiquidCrystal_I2C library is updated and lcd.begin(); will not work anymore if its empty between (), try this: #include <Wire.h> #include <LiquidCrystal_I2C.h> #include <Keypad.h> LiquidCrystal_I2C lcd(0x27, 16, 2); // Set the LCD I2C address and dimensions const uint8_t ROWS = 4; const uint8_t COLS = 4; char keys[ROWS][COLS] = { { '1', '2', '3', 'A' }, { '4', '5', '6', 'B' }, { '7', '8', '9', 'C' }, { '*', '0', '#', 'D' } }; uint8_t colPins[COLS] = { 5, 4, 3, 2 }; // Pins connected to C1, C2, C3, C4 uint8_t rowPins[ROWS] = { 9, 8, 7, 6 }; // Pins connected to R1, R2, R3, R4 Keypad keypad = Keypad(makeKeymap(keys), rowPins, colPins, ROWS, COLS); void setup() { Serial.begin(9600); lcd.init(); // Initialize the LCD lcd.backlight(); // Turn on the backlight lcd.setCursor(0, 0); // Set the cursor to the top-left corner } void loop() { char key = keypad.getKey(); if (key != NO_KEY) { lcd.print(key); // Display the pressed key on the LCD } }

there are errors in my google script file even though i followed the instructions. please help.

do the black keys work?

It's fake!!!!!

it’s fake!!!

hir sir..how fast the data transfer? if i`m using direct HTTP to google sheet, the delay will be approximately 6 sec. i saw from the video, no issue with 3 sec data stamp. is it can go up to 0.5 sec for data logging?
