Wireless weather station u sing Arduino Dear friends welcome back! Today we are going to build a wireless weather station project using Arduino.Without any further delay, let’s get started! A Wireless Weather Station with a big 3.2” Color TFT display. The project is up and running,and it displays the current date and time, the indoor temperature and humidity, and the outdoor temperature and humidity. The readings of the outdoor sensor are updated every second in order to demonstrate that we have a reliable communication link established with the transmitter which is outside at a distance of 5m. The readings of the indoor sensor are updated once every minute. The heart of the project is the fast Arduino Due, there is no flickering of the screen when the values are updated. Let’s now see the transmitter. The transmitter is much simpler. It consists of an Arduino Nano, a DHT22 sensor and the NRF24L01 wireless transceiver module. The transmitter reads the temperature and ...
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...
