Install VNC Server in Raspberry PI

Setting up your Raspberry Pi

VNC Connect is included with Raspbian but you still have to enable it.

First, run the following commands to make sure you have the latest version of VNC Server and VNC Viewer:

sudo apt-get update 
sudo apt-get install realvnc-vnc-server 
sudo apt-get install realvnc-vnc-viewer

If you’re already using an older version of VNC Server, restart it. If not, and you’re already booted into the PIXEL desktop, select Menu > Preferences > Raspberry Pi Configuration > Interfaces and make sure VNC is set to Enabled.

Alternatively, run the command sudo raspi-config, navigate to Advanced Options > VNC and select Yes.

Konfigurasi Sensor Vibration on Rapberry PI

SCHEMATIC:

Python Code:

#!/usr/bin/python
import RPi.GPIO as GPIO
import time

#GPIO SETUP
channel = 17
GPIO.setmode(GPIO.BCM)
GPIO.setup(channel, GPIO.IN)

def callback(channel):
        if GPIO.input(channel):
                print "Gerakan Terdeteksi!"
        else:
                print "Gerakan Terdeteksi!"

GPIO.add_event_detect(channel, GPIO.BOTH, bouncetime=300)  # let us know when the pin goes HIGH or LOW
GPIO.add_event_callback(channel, callback)  # assign function to GPIO PIN, Run function on change

# infinite loop
while True:
        time.sleep(1)

Konfigurasi Sensor PIR on Rapberry PI

How it Works

PIR (passive infrared) motion sensor detects any movement of objects, human or animals. Mostly they are used in automatically activated lighting and burglar alarm systems.

Every object with temperature above absolute zero emit heat in the form of infrared radiation. PIR motion sensor detects change in the infrared radiation impinging on it. When any object or human passes in the front of the PIR sensor, the temperature in sensor’s field of view will rise from ambient temperature to object temperature and then back again to ambient temperature. PIR sensor converts this temperature change into the change in output voltage and that change in voltage is considered as motion detected.

Components

PIR Sensor

1 / 2 • PIR Sensor

PIR Sensor

Sensor

Sensor has three pins. Power (VCC), Ground (GND) and output (OUT) pin which gives logic high if motion is detected. It has two potentiometers. One for sensitivity adjustment and second for adjusting the time the output signal stays high when motion is detected.

VCC, OUT and GND pins

Potentiometers to adjust Sensitivity and Output Time

Python Code : 

import RPi.GPIO as GPIO

import time

GPIO.setmode(GPIO.BCM)

GPIO.setup(23, GPIO.IN) #PIR

GPIO.setup(24, GPIO.OUT) #BUzzer

try:

    time.sleep(2) # to stabilize sensor

    while True:

        if GPIO.input(23):

            GPIO.output(24, True)

            time.sleep(0.5) #Buzzer turns on for 0.5 sec

            GPIO.output(24, False)

            print("Motion Detected...")

            time.sleep(5) #to avoid multiple detection

        time.sleep(0.1) #loop delay, should be less than detection delay

except:

    GPIO.cleanup()
