The right way to add a touchscreen to your Raspberry Pi initiatives

You simply want a Raspberry Pi, a touchscreen show, and a screwdriver.

You in all probability already understand how versatile Raspberry Pi computer systems are. However it’s not till you add a show that you simply actually get to expertise the true energy and suppleness of this platform.

And never any previous show, however a touchscreen show.

Here is what that you must do construct a touchscreen pc utilizing a Raspberry Pi.

First, you want a Raspberry Pi. That is simpler stated than carried out given that they are in brief provide, however store round and you may in all probability discover one (here is ZDNET’s recommendation on the place to purchase the Raspberry Pi 4 and options).

In case you have an older Raspberry Pi 3 mendacity about, you should use that with this show.

Here is mine – it is an 8GB Raspberry Pi 4 B.

Then you definitely want a show.

There are a selection of shows on the market, however the one which I am utilizing right here is the official Raspberry Pi 7-inch 800 x 480-pixel touchscreen.

That, plus a Phillips-head screwdriver, is the minimal you want, however I’ve gone a bit additional right here and added a case as properly.

The case helps defend the Raspberry Pi and the show from injury, and makes it really feel like a correct pc versus a homebrew mission.

Now that you’ve all of the components you want, here is the method for including the touchscreen show to your Raspberry Pi.

1. Join the all-important ribbon cable

Becoming the show is fairly simple, however the first bit can be the fiddly bit as a result of it includes utilizing tiny ribbon cable.

To connect the ribbon cable to the connector on the show, first discover the show connector. There’s a bit of grey plastic tab on this connector that must be slid again to permit the ribbon cable to be fitted. Push the ribbon cable so far as it would go after which press the grey tab again into place to safe the ribbon cable.

The ribbon cable in my equipment had a blue aspect, and the directions stated to have this aspect going through towards the circuit board. Your ribbon cable is perhaps totally different, so test your directions.

2. Connect the Raspberry Pi to the show controller

Subsequent, I fitted the Raspberry Pi to the board, attaching it with the 4 screws.

You do not want to overtighten these screws!

3. Connecting the jumper wires

I additionally wanted to attach 4 jumper wires to the show’s management board. It would not matter which coloration you join the place, however that you must know which is which since you’ll want to attach them to the suitable pin on the Raspberry Pi in a bit of bit.

For reference, listed here are the 4 connections and which pin on the Raspberry Pi they must be linked to:

  • 5V –> Pin 2 or Pin 4
  • GND –> Pin 6
  • SDA (knowledge) –> Pin 3
  • SCL (clock) –> Pin 5

Trying on the Raspberry Pi board with the writing within the appropriate orientation, pin 1 on the 40-pin connector alongside the highest is on the underside left, and pin 40 is high proper.

4. Connecting that vital ribbon cable to the Raspberry Pi

Keep in mind that ribbon cable you linked to the show controller?

Now’s a very good time to attach the opposite finish to the Raspberry Pi. The method is similar as for connecting it to the show controller.

5. Match all the pieces into the case

Subsequent, I popped the entire meeting into the case. It took a little bit of fiddling to get the show into the case correctly, however all the pieces appeared to fall into place as soon as the screws had been fitted. You possibly can inform when it is in place correctly as a result of the ports will line up with the cutouts.

Once more, you do not want to overtighten these screws.

6. You are carried out!

You have added a touchscreen show to your Raspberry Pi! Fireplace up your Raspberry Pi and replace the software program, and also you’re able to take your initiatives to the subsequent degree.
