Digital Keypad Security Door Lock using Arduino Hi everyone, welcome to another blog tutorial,in this tutorial I will teach you how tomake this password enabled entry. Components: 4X4 matrix keypad membrane keypad 16X2 LCD Arduino Servo Motor Connecting Wires Potentiometer Circuit Diagram: Description: I'm using as an improvised enclosure and this is the door, this is a 4X4 matrix keypad, membrane keypad, this is a 16X2 LCD.So, what this system does is this, like I said it’s a password enabled entry, so, I programmed the system with Arduino, so,when you enter the wrong password using this 4 by 4 matrix keypad the door will not open and the password you entered will be displayed on this LCD, but once you enter the right password, the door will open, then it will remain open for 5 and then close. So, the components or for the parts I usedin the design you can see here I have a motor driver this is a motor driver to drive the motor that opens and closes the door, this is a potentiomet
Motion Detector With Photo Capture Camera Hello friends!! Welcome to This Blog. In this Blog, we will make a motion sensor detector with photo capture using ESP32CAM and the PIR module. The logic behind is when the PIR sensor detects any motion, the ESP32CAM will start taking the pictures. So you can use this project as a security camera. In thisblog, I will share the circuitdiagram, Arduino sketch, and the component list, so after reading the complete article you can easily make this project. Now ESP32 CAM is a small camera module that has ESP32S chip on the back and some GPIO pins to connect peripherals and it also has a micro-SD card slot, where you can insert the micro-SD card and store the pictures. Now before going to the circuit diagram and Arduino sketch, let me give you a quick overview of this project. Components Required ESP32-CAM PIR Motion Sensor Module BC547 NPN Transistor 220ohm, 1k, 10k Resistor. LED 5-mm FTDI 232 USB to Serial Interface board 5 volt DC supply The
