Top 10 Raspberry Pi Projects for Beginners in 2020

10. Brushless DC Motor Control using ESC with R-Pi:

Link to the project video:

Objective:

To drive a Brushless DC Motor using an Electronic Speed Controller(ESC) with Raspberry Pi and measure the RPM of the motor.

This is a low-cost project as the BLDC motor is salvaged from an old Hard drive and the Electronic Speed Controller(ESC) used is cheap. Use an I2C numeric LED display to display the RPM or speed of the driven BLDC motor. And use a BCD pull switch is used as a throttle increase the speed of the motor.              

Components you need for this project are:

1) Raspberry pi Board

2)  BLDC motor

3) Connecting Wires

4) Electronic Speed Controller

5) TCRT5000 non-contact reflective optical sensor

6) Resistors 10k, 1.1k, 2k ohm

7) 12v Power supply

7. Servo Motor Control using Raspberry pi

Source: @Expalining Computers

OBJECTIVE:

Understanding the basics of Servo motor and using a Raspberry pi to control the rotation of an SG90 servo motor.

This tutorial gives a nice idea of the working of a servo motor and how it differs from a normal DC Motor. The servo motor used here is SG90. And controlled in Python on a Raspberry Pi. This tutorial also gives a brief introduction to Pulse width Modulation(PWM).        

Components you need for this project are:

1)  SG90 servo Motors

2) Raspberry pi Board

3) Connecting Wires

6. Weather Station using Raspberry Pi using DHT22 Sensor

OBJECTIVE:

Building a weather station using the DHT22 sensor and  5′ inch touch display

The touch screen displays the live update of the temperature and humidity of the surroundings in which DHT22 sensor is placed. The value of temperature and humidity are updated every two seconds on the screen. To use the Raspberry Pi for other purposes, you can touch on the screen and the application gets paused. 

Components you need for this project are:

1) Raspberry Pi Board

2) DHT22 Temperature and humidity sensor

3) Connecting Wires

4) 5′ inch touch display

5. Stepper Motor Control Using Raspberry Pi

OBJECTIVE:

Understanding the basics of a stepper motor and using a DRV-8825 stepper motor driver with Raspberry pi to control the rotation of bipolar stepper motors.

This tutorial gives a nice idea of the working of a stepper motor and how it differs from a normal DC Motor. The stepper motor used here is NEMA 23 570 oz-in bi-polar stepper motor from a CNC router. To control the motor, stepper motor driver DRV-8825 is used in Python on a Raspberry Pi.
