Servo motor interfacing with Raspberry pi 3

In this blog,I will explain you how to interface servo motor with Raspberry pi 3.

This project uses Python scripts run on a Raspberry Pi microcontroller to send GPIO PWM outputs to a servo motor to set its angle. If all that sounds confusing, don't worry, I'm about to explain it.

Components Required

1. Raspberry pi 3

2. Servo motor

3. Jumper wires

Circuit Diagram

Connections

Raspberry pi-----------------------------Servo motor

  VCC(pin2)-------------------------------Servo red wire

  GND(pin39)-----------------------------Servo black wire

  GPIO4(pin7)----------------------------Servo orange wire

A servo motor is a type of DC motor that, upon receiving a signal of a certain frequency, can rotate itself to any angle from 0-180 degrees. Its 90 degree position is generally referred to as 'neutral' position, because it can rotate equally in either direction from that point.

Procedure

Step1- Make connection as shown in above figure.

Step2- connect red wire of servo to pin2 of raspberry pi and black wire of servo to                    pin39 of raspberry pi and orange wire of servo to pin 7 of raspberry pi.

Step3- Download the code from given link.

Step4- Open the downloaded file in python software.

Step5- If you want change the GPIO pin just edit it with your own GPIO pin.

Step6- Run the program anf you will see servo start moving.

How to make DIY quadcopter using Arduino Uno.

In this blog, I will explained you how to build your own quadcopter using Arduino Uno.

Components Required

1. Arduino Uno

2. Quadcopter Frame typeX

3. Flysky Receiver

4. 6 Channel Transmitter

5. 4 ESC 30A

6. MPU6050

7. 4 Brushless DC Motor

About Quadcopter

Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counterclockwise (CCW). These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust.Each rotor produces a thrust and a torque about its center of rotation and these forces are used to fly and move quadcopter. Two rotors mounted on opposite arms of quadcopter are set into clockwise and another two anticlockwise direction of motion. These position of motors and their direction of rotation cancels all the torque generated given the speed of the motors are same.

Why Arduino as a flight controller ?

There are lots of flight controller available in Market like

1.Naze32 Flight Controller

2.OpenPilot CC3D Flight Controller

3.EagleTree Vector Flight Controller

4.Hobbyking KK2.1 Flight Controller

5.ArduPilot Mega APM 2.5Flight Controller

But i chosed Arduino Uno because it cheap and easy availabe in market.

Arduino uno work on Atmega328p microcontroller which is 8 bit microcontroller have enough processing speed and Clock Speed 16 MHz, Can provide 8-bit PWM output with the analogWrite() function.

About Transmitter and Receiver

For my quadcopter I used FlySky CT6B 2.4Ghz 6CH Transmitter with FS-R6B Receiver is the popular 6 Channel Radio CT6B manufactured by FlySky.CT6B FLYSKY 2.4GHZ 6CH TRANSMITTER radio is a value for money, entry level 6 channel transmitter, ideal for quadcopters and multicopters that require the 6ch operation.CT6B FLYSKY 2.4GHZ 6CH TRANSMITTER is an entry-level 2.4 GHz radio system offering the reliability of 2.4 GHz signal technology and a receiver with 6 channels. It can be powered by 8 x AA Size Batteries or a 12V Power Supply. It comes with a trainer port to help beginners learn flying.It can be configured by connecting it to the computer. Use the T6config software to configure your radio on a computer.

About Electronic Speed Controller

I used 30A BLDC ESC ELECTRONIC SPEED CONTROLLER can drive motors which consume up to 30A current. It works on 2S-3S LiPo batteries. It has an onboard BEC which provides regulated 5V(2A max draw) to power the flight controller and other onboard modules. It can be used to control our brushless motors with a 2S-3S LiPo (make sure motor doesn’t draw more than 30A).30A BLDC ESC Electronic Speed Controller is specifically made for quadcopters and multi-rotors and provides faster and better motor speed control giving better flight performance compared to other available ESCs.

How to configure your Quadcopter

Step1 Download and compile setup code. 

Step2 Download and compile ESC calibration code.

Step3 Finally download and compile Flight code.

How to control your quadcopter

Controlling a quadcopter is alway risky make sure all four propellers are tightly screwed .Don't try this at home.For Arming the quadcopter put throttle down and put yaw left now slowly move the throttlr up. For Disarming the quadcopter put the throttle down and put the yaw right.

Why Q100  Frame?

The Q100 is a mini-size smallest frame among the quadcopter frame class.This is ready-2-fly quadcopter frame requires only basic installation. You can enjoy the versatility of the Q100 racing drone by practicing your flying, racing, or aerial acrobatic drone skills either indoors when it’s raining, or outdoors when it’s sunny.The arms of the frame are attached permanently to the frame and can’t be removed. The upper colored cap at the front of the frame can be attached and detached while assembling.

Why Eachine h8 Flight Controller?

Basically It is receiver board Compatible with: JJRC H8 Mini QuadcopterItem dimension: 4.3 * 4.2 * 0.2cm .Its weight is only 3g. In this board we can connect four coreless DC motors. This board is highly stable as compared to other boards at this price. It works on 2.4ghz radio frequency. It is compatible with any transmitter which work on 2.4GHz.

Why 8520 coreless motor?

This 8520 Magnetic Micro Coreless Motor is very compact and lightweight DC motor nicely crafted for perfectly matching with your small 100mm like multirotor frames.These lightweight brushed DC coreless motors are the best choice for your small drone, offering you an excellent affordable price when compared with costly BLDC motors.They are rated at 39000 RPM which is more than needed to lift and push your drone to the target. These are less noisy with low resistance. The only drawback of using coreless is the amount of torque they provide, as they are High Speed and Low Torque motors.

Why 2.4GHz Transmitter? 

2.4GHz system is an entry level transmitter offering the reliability of 2.4GHz signal technology and a twin receiver antenna and with 6 channels.This transmitter requires 8 AA batteries.Easy to use control for basic models.We can use this for all sorts of projects including (but not limited to) tanks, airplanes, helicopters, scale models of the Weinermobile.This radio has very lightweight and handy design with two retract switches and proportional flap dials in easy reach for channels 5 and 6.

What is DHT11 Sensor?

DHT11 Temperature & Humidity Sensor features a temperature & humidity sensor complex with a calibrated digital signal output. By using the exclusive digital-signal-acquisition technique and temperature & humidity sensing technology, it ensures high reliability and excellent long-term stability. This sensor includes a resistive-type humidity measurement component and an NTC temperature measurement component, and connects to a highperformance 8-bit microcontroller, offering excellent quality, fast response, anti-interference ability and cost-effectiveness.


Google Firebase Setup
Firebase provides a realtime database and backend as a service. The service provides application developers an API that allows application data to be synchronized across clients and stored on Firebase's cloud. The company provides client libraries that enable integration with Android, iOS, JavaScript, Java, Objective-C, Swift and Node.js applications. The database is also accessible through a REST API and bindings for several JavaScript frameworks such as AngularJS, React, Ember.js and Backbone.js. The REST API uses the Server-Sent Events protocol, which is an API for creating HTTP connections for receiving push notifications from a server. Developers using the realtime database can secure their data by using the company's server-side-enforced security rules.

Step1 Make a account in google firebase and login .

Step2 Add a project with name.

Step3 Go to project overview then users and premissions.

Step4 Go to data base secret and then copy api key.

Step5 Go to database and change cloud firestore to realtime database.
