Hello everyone. Welcome to the video number 3.2. And in
this video we're going to assemble the hardware for
the Smart Lock that we will control with
the Bluetooth. So guys,
let's get started with that in the first video. We're going to assemble the
hardware and in the next video, we're going to code the
board to control the lock using
the Bluetooth and in the third video we're going
to do while at the mobile app using MIT
app and winter to make a
custom app and install in your mobile phone and control the
lock. So guys, let's get started with that.
Okay, and we need to connect the
pins.
with the esp32
So we need three pins 3 volt ground and the D2
and I'm going to use the red pin with the
three volt.
To control the relay and brown with
the ground.
and that orange with the
D2 for the signal, okay.
So you guys can get the idea 3 volt ground and
the t2, okay.
so here
now we need to connect it with the relay as first one
is the signal second one is the plus and the
last one is the negative. So orange goes to
the signal red goes to the positive and
the Brown goes to the negative and
here we are good to go with that set up.
Okay, and in the last we
need to connect the lock with the
charger.
And with the really to take a one cable.
with the red
and join the cables
and take the screwdriver.
Loose the nuts.
of the comb
and we have a comb and the NC normally
closed.
Put that cable in the center in the comb.
and the NC
just put the log cable.
And again attach that cable.
With the red one.
And now we are good to go with that. And in the next video
we're going to do the code how to enable the Bluetooth and
how to send the data from the mobile
to
esp32 and listen the data using a Bluetooth
serial terminal app, so I see you in
the next video. Have a good day. Bye.
