Story

Why I Made This:

So as COVID-19 is going on that's why we need to take some precautions Use mask, Hand sanitizer, Zero contact with anybody.
So I made this to avoid to touch the doorknob and open it( I'm a lazy person )

How I Made This:

As I have the core kit of M5Stack there is no imu in it. so that's why I added an MPU6T050 in it. to get all data I need.
I use some female headers to connect it

and connected it to M5Stack.

VCC ---- 3.3v

GND ---- GND

SCL ---- SCL

SDA ---- SDA

M5Stack(client):

M5Stack will work as a remote control for the robot.
with MPU6050 we are calculating "ROLL".

WEB CLIENT:

so here we are working as a client for the server.
so it's similar to web server, where we give commands from our devices to the board,

MPU6050:

so I'm using the sketch that comes with the M5Stack library.

I'm modifying the sketch as per my need.

NodeMCU(server):

so we begin a server that reads what client print.
so as I gave the example up there that if server reads led then it will open or close or do as per commands.
to ensure that it's working you can also connect to the server with your phone and type "ope" to check everything is working or not.
so let's talk about the connection.

I'm using here a relay to control solenoid.
D1 ---- SERVO(data)
GND ---- GND
VCC ---- VCC

library:

you will find the M5Stack library here.
you will need servo.h that is pre-installed.

CLIENT SIDE:

if(roll >= 40){
  M5.Lcd.print("[HTTP] begin...\n");
        
        http.begin("http://192.168.4.1/ope"); 
        M5.Lcd.fillScreen(Green);        
        int httpCode = http.GET();

        http.end();

So when you tilt your hand right then the Oval of the sensor goes up to 40 then it will write ope(it's just a code to say, Hey open the door to NodeMCU).
the screen color of M5STACK will change "RED" to "GREEN" when the door is opened.

so I'm using this type of wrist band for M5STACK.

SERVER SIDE:

void ope(){
  myservo.write(90); 
  delay(10000);
  myservo.write(0);

if the client writes "ope" Nodemcu will follow this void ope and open the door.

if you have any problem with it then do let me know in the comment section.
