Creating an Account on Azure

NOTE: Some may say that you need .edu domain only but now GitHub, Azure accepts all student domains mine got accepted (.ac.in), if yours doesn't then contact GitHub Support and explain them that you are a student but your email was not accepted. They'll contact you in a few days with a code to use for a student's subscription

Controlling Esp8266 using Arduino IoT Cloud

Beginner

Intermediate

Step By Step Guide On Building This Project

Uploading Code to Stm32f103c8 (Bluepill Board)

Using this procedure one can upload Code to Stm32f103c8

Resources Needed for Initial Configuration(Booting) Stm32f103c8

Once code is uploaded Connect Stm32f103c8 to Ultrasonic sensor(HC-SR04), GPS sensor(Neo-6m) and Esp8266

Pinout of Stm32f103c8

RX1,TX1 -> Hardware Serial 1
RX2,TX2 -> Hardware Serial 2
RX3,TX3 -> Hardware Serial 3

Connecting ESP32 to Arduino IoT Cloud

https://docs.arduino.cc/arduino-cloud/getting-started/esp-32-cloud

Using this same procedure one can connect Esp8266 and other Esp Boards to Arduino Iot Cloud

Creating virtual variables for Esp8266

Once above step is done you would see get 1 thing on this page

Click on the thing and start creating variables

Set Permission and Update policy for variables:
forward

backward

right

left

distance

gps

led

servo

motor

Creating Dashboard and Connecting Virtual Variables

Add the following widgets:

1 Switch

4 Push Buttons

1 Map

1 Value

2 Slider

Place them as shown below

Connect Widgets to Virtual Variables

forward

backward

right

left

distance

gps

led

Creating a VM on Azure

Login on Azure and go to Virtual Machines

Video Tutorial

Once Machine is created open Ports on it to use Websockets for the Camera Stream

Go to Networking

Add

Open the same port for OutBound Connection

Add

Using Above Steps You can create more a secure rule than mine, like accepting from a specific IP only (but I chose not to as this is just prototyping for a personal project

Follow this next on Your VM

NOTE: In the Video the VM is made on GCP we made the same thing on Azure, follow the same steps as showed in the video after this the stream should show in the "<PublicIPofVM>/client" url

Once done now upload code to ESP8266 to Control Car

Go to Sketch

Install Arduino Create Agent

Click on Learn More then Download

Copy Paste the code from my github repo Arduino_iot_cloud_Nodemcu and upload the sketch to your nodemcu

NOTE: To burn code use these videos as reference

Circuit Connections:

THE CAR MUST FUNCTION NOW PROVIDED YOU FOLLOWED ALL STEPS PROPERLY

The Connection Overview of GPS, Ultrasonic, STM32, Esp8266 have been shown here
