Raspberry_Pi_Introduction

Using the Raspberry Bi Camera Module

The Raspberry Pi 5MP Camera Board connected with the Raspberry Pi 4 board we can capture images and videos very easily. There are several functions available in example_picamera.py that allows for the above mentioned operations.

Using the HC-SR04 Distance Sensor

HC-SR04 Distance Sensor connected with the Raspberry Pi 4 board we can easily detect distance. HC-SR04 has 4 points of connection (i)VCC which is connected to 5V power supply (ii)Gnd which can be connected to anyone of the Ground pins (iii) Trigger and Echo can be connected to any of the GPIO pins. distance.py contains source code for operating distance sensor with Raspberry Pi 4.

4 X 4 Motor Control Using L289n Board

L289n can be used to control multiple motors, they can be used for speed and movement control.
