How to make a quadcopter using esp8266 and controlled it by your smart phone.

In this blog, I will explained you how to build esp8266 based quadcopter using Arduino Uno and controlled it by smart phone.

Components Required

1. Arduino uno

2. ESP-01/ESP-12

3. MPU6050

4. ESC(Electronic Speed Controller)

5. Brushless DC motors

6. Breadboard

7. Jumper Wires

8. Quadcopter Frame

9. FTDI or TTL

Procedure to make WIFI Quadcopter

Step1-make a connection of esp01 as given.

Step2- Open the wifippm code

         -->If you are using esp8266(esp-12) set GPIO5 pin as PPM output pin and GPIO4                pin as debug pin.

         -->If you are using esp8266(esp-01) set GPIO2 pin as PPM output pin and GPIO3                pin as debug pin.

Step3- upload the wifippm code to esp01 with the help ttl or ftdi.

Step4- After upload the code remove the Rx Tx GPIO0 and CH_pd pins.If a hotspot is              created named wifippm then everythings is alright.

            If hotspot is not created then connect Ch_pd pin to 3.3v and reset the                            esp01(means off and again on).

Step5- Now place all the components on the frame and make a connection as shown              in figure

 Step6- open multiwii.ino firmware go to config.h and uncomment the following                   lines.

             The type of multicopter----------> #define QUADX 

             Combined IMU Boards-------------> #define GY_521 

             PPM Sum Reciver ------------------> #defineSERIAL_SUM_PPM(PITCH,ROLL,THROTTLE,YAW)      

Step7- upload the code in arduino uno board.

Step8- open the multiwii gui select the board and click the start button. Move your                   quadcopter and you can seen the reading of gyroscope and acclerometer.                 

Step9- connect your phone with wifipmm hotspot and open any browser and type                    192.168.4.1

Step10- move the joystic in browser and you can see the changes in multiwii gui.
