An Automatic Door Opener System is a simple project based on PIR Sensor and Arduino, which automatically opens and closes the door by detecting a person or object. You might have seen Automatic Door Opener Systems at shopping malls, cinemas, hospitals etc. where, as soon as a person approaches the…
In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. Such Automatic Room Lights can be implemented in your garages, staircases, bathrooms, etc. where we do…
In this tutorial, we will learn about 4×4 Matrix Keypad and how the Arduino Keypad Interface works. A Keypad is an input device that is used to enter passwords, dial a number, browse through menu and even to control robots. You might have seen keypad being used at ATMs, Security…
In the previous DS18B20 Digital Sensor Project, we have seen how to interface Arduino with DS18B20 and display the temperature on a 16X2 LCD Display. In this project, we will learn about the Raspberry Pi DS18B20 Temperature Sensor interface and also how to monitor the temperature from a remote location…
In this project, we will learn about the one-wire Digital Temperature Sensor DS18B20 and how the Arduino DS18B20 interface works. Temperature Sensors are very important devices as they help us in measuring, monitoring and maintaining the temperature of a room, instrument or a device. Previously we have used the very…
In this project/tutorial, we will see how to connect a simple Push Button to Raspberry Pi and how to accept input from the GPIO Pins of Raspberry Pi. Interfacing a Push Button with Raspberry Pi is very easy and the idea behind the project is to understand the concepts behind…
