Let's have a quick look at how way to display the world in the sense that I want to be, especially
to when I was looking for the appropriate components for this project, I wanted components that are
easy to connect to.
That means the least amount of wiring is necessary, the fewest possible wires.
And then the next step from that is to also try to use the least number of communications interfaces.
So based on components that I have played with and examined in the past, I was able to find the BMY.
Two hundred and eighty sensor and the squid see two by 16 character display the LCD display that both
work on the squid sea communications interface.
And I've also tested them so that I can confirm that both of them work on the E.S.P 32 hardware interfaces
instead of software interfaces.
Some of the other displays that I've played with the already displays in particular would only work
on the software interface.
So if that was the case, then I would need to use a hardware I could see and a software I could see
interface.
And that again would require Maguires that I wanted to avoid.
So this combination is ideal hardware interface for the display hardware interface with a sensor.
Both of them go on to interface with the zero which work on on Jupitus 18 and 19, as you can see here
as well, in the micro python.
That limitation for the specific two, we have to hardware, it's could buses and using this one here
at Pince GPO 18 and 19.
So I've done the necessary connections are used jumper wires to break out those two panes, connect
them to the sensor into the city.
Now, one point of differentiation between the two devices is that sensor is a three point three foot
device.
So I've connected to the three point three volt power array here, which takes power from this pen right
here on the east, three to three point three volts.
The LCD screen, though, requires five volts.
So I got that from the five both pin on the ASPCA to buy this green wire.
So I was able to power the LCD that way.
The ground, of course, for both devices is the same for the activity entity that's connected to Tapio
21 with a two hundred and twenty on current limiting resistor to ground.
So the anode is connected to CHIBBARO twenty one.
And that's it with the hardware, fairly simple.
Let's move on to the next election to have a look at the screen.
