Interfacing HC-SR501 PIR Motion Sensor with Raspberry Pi

All living beings radiate energy to the surroundings in the form of infrared radiations which are invisible to human eyes. A PIR (Passive infrared) sensor can be used to detect these passive radiations. When an object (human or animal) emitting infrared radiations passes through the field of view of the sensor, it detects the change in temperature and therefore can be used to detect motion. HC-SR501 uses differential detection with two pyroelectric infrared sensors. By taking difference of the values, the average...

HC-SR04 Ultrasonic Sensor

Interfacing HC-SR04 Ultrasonic Sensor with Raspberry Pi

HC-SR04 Ultrasonic Sensor Ultrasonic distance sensors are designed to measure distance between the source and target using ultrasonic waves. We use ultrasonic waves because they are relatively accurate across short distances and don't cause disturbances as they are inaudible to human ear. HC-SR04 is a commonly used module for non contact distance measurement for distances from 2cm to 400cm. It uses sonar (like bats and dolphins) to measure distance with high accuracy and stable readings. It consist of an ultrasonic transmitter, receiver...

LCD Custom Characters

Custom Characters on LCD using PIC – MikroC

I hope that you already go through our tutorial, Interfacing Character LCD with PIC Microcontroller - MicroC Pro. These character based LCDs are commonly made using HD44780 compatible controllers. It allows us to define 8 custom characters in addition to the standard pre-programmed characters. In this tutorial we will learn to define our own custom characters using MikroC compiler. DDRAM, CGROM and CGRAM CGROM - Character Generator ROM This is the memory which holds 5x8 or 5x10 dot patterns of predefined characters in...

vnc

Using Raspberry Pi through VNC

Virtual Network Computing (VNC), is a graphical desktop sharing system used to remotely control a computer's desktop from another computer. It uses Remote Frame Buffer Protocol (RFB). It transmits keyboard strokes and mouse movement from the controller to the remote host and relays back the graphical screen updates from the host, over a network like Ethernet. Installing a VNC server like TightVNC on Raspberry Pi enables the user to remotely access the desktop of Pi and perform necessary operations. This is...

SSH

Accessing Raspberry Pi through SSH

SSH stands for Secure Shell. It is a secure channel created over an insecure network. The channel consists of a server and a client. This channel uses public key cryptography and can be used for secure transmission of passwords, remote log in, command execution etc.. SSH can be used when we cannot physically access the Raspberry Pi due to various reasons like the USB ports are engaged or the board is in a remote location. This method also minimizes hassle of...
