pihole 2.8 tft lcd sheild manufacturer

This guide will show you how to setup and configure your Pi hole to display the pi hole system status and ads blocked using the Pi Supply Media Center HAT. The Pi Supply Media Center HAT is a 2.8″ TFT display that connects to your Raspberry Pi, and includes other feature such as IR receiver, restive touch and navigation buttons that can be soldered to the PCB.

Step 4 – Install the Media Center HAT software. We want to display the main output on the TFT display only, from the command line type in the following:

3 Overview We already have a guide on using Pi-Hole with the Raspberry Pi Zero W ( to send advertisements on your network into a black hole. But, the PiOLED is small and we want to monitor more statistics at a glance. While we could open the web console to monitor Pi-hole, we can"t show that to friends easily. Plus, who doesn"t want more shiny, blinky, networking hardware? We"re going to install PADD ( (Pi-hole Ad Detection Display) and Pi-Hole ( on the Adafruit 3.5" PiTFT Plus to display useful and fun statistics such as Amount of Pi-holed Advertisements, and the top offending domain attempting to serve pesky advertisements to your network. What"s Pi-hole? Pi-hole ( is an open-source project which let"s your Pi act as a DNS (Domain Name Server). While you may have an ad-blocker installed on your browser, do you have one on your phone? What about blocking inapplication advertisements in your mobile games? On your Smart TV? On your smart fridge? Pi-hole lets you block ads from any device configured to use it as a Domain Name Server. When an advertisement (i.e: ads.adserver.com) tries to resolve it"s IP address, Pi-hole will return nothing back. You"ll never connect to the advertisement server and the ad won"t even load. This makes it quicker, faster, and use less data than conventional ad blockers. Parts You"ll need the following parts to get up-and-running with Pi-hole and PADD Adafruit Industries Page 3 of 27

4 You need a Raspberry Pi with built in wireless. The Raspberry Pi 3 line (3, 3 B, 3 B+) devices are wireless-ready without external configuration: 1 x Raspberry Pi 3 Model B GHz Cortex-A53 with 1GB RAM ADD TO CART You"ll also need a power supply for your Pi and a MicroSD card for holding the Pi"s OS and it"s applications: 1 x 5V 2.4A Power Supply 5V 2.4A Switching Power Supply with 20AWG MicroUSB Cable ADD TO CART 1 x 8GB MicroSD Card 8GB Class 10 SD/MicroSD Memory Card - SD Adapter Included ADD TO CART PiTFT Display To use the full version of PADD, you"ll need a PiTFT supporting a resolution of at least 480x320. If you"re using a display smaller than 480x320, PADD will boot into a mini mode which displays way less statistics about the network. To view PADD, we suggest using the PiTFT Plus 3.5": PiTFT Plus 480x " TFT+Touchscreen for Raspberry Pi $44.95 IN STOCK ADD TO CART If you happen to have one of our 2.8" or 2.4" PiTFT ( those will work too Other Parts We used a Pi 3 case to protect our Pi from aesthetics and to protect our Pi against scratches, bumps, and falls. The case also makes the Pi-hole look like a networking appliance. Adafruit Industries Page 4 of 27

15 PiTFT Configuration Assembly If you are using a case like the Adafruit Raspberry Pi Case ( snap-fit the Pi into the case: Leave the clear top off, we"ll need to access the GPIO header for the PiTFT. The PiTFT"s four mounting ears can be used to attach the display to a bezel. But, we"ll be snapping them off with pliers (they"re perforated) for a flush-fit with the case/ Adafruit Industries Page 15 of 27

16 Position the PiTFT over the 2x20 GPIO connector and press downwards. Make sure the PiTFT"s header is flush against the GPIO header. Now that our PiTFT is assembled, let"s configure the display to work with our Pi. Adafruit Industries Page 16 of 27

17 PiTFT Configuration You"ll need to perform some configuration to get the PiTFT up and running. We"ll do this through the PiTFT installer script. This script will do all the work for you, and install both device tree overlay support as well as configure rotation and any HDMI mirroring. PiTFT no longer needs any custom kernels or modules, so you can continue to update/upgrade your Pi and it will work with the most recent releases. Here"s the commands to run. Make sure your Pi has network access, it needs to download the software! cd ~ wget chmod +x adafruit-pitft.sh sudo./adafruit-pitft.sh Adafruit Industries Page 17 of 27

18 Once./adafruit-pitft.sh is run, we"ll be presented with menus. Since we"re using the 3.5" PiTFt, we"ll select #4 We"ll also need to select a rotation of 270 degrees (#3) so the PiTFT + case can sit on your desk when the USB cable is plugged in. We"re going to want to use the PiTFT as a text console for PADD, type Yes to the question Would you like the console to appear on the PiTFT display Adafruit Industries Page 18 of 27

20 Install PADD Next we"re going to install PADD ( the Pi-hole Ad Detection Display. This application displays statistics about advertisements, your Pi"s status, network configuration and system statistics on your PiTFT. It is written and maintained by Jim McKenna who did an awesome job! ( In the SSH session with your Pi, navigate to your home directory: cd ~ Grab a copy of PADD: wget -N Make PADD executable by running: sudo chmod +x padd.sh Open PADD at Pi Bootup Next, we"re going to set PADD to open automatically on your PiTFT when we start our Pi. Open ~/.bashrc : nano ~/.bashrc Navigate to the end of the file (by pressing the down arrow key) and add the following text: Adafruit Industries Page 20 of 27

21 # Run PADD # If we"re on the PiTFT screen (ssh is xterm) if [ "$TERM" == "linux" ] ; then while : do./padd.sh sleep 1 done fi Save (control+o) the configuration and exit (control+x) nano to be brought back to the terminal. Turn off the PiTFT at Night The PiTFT is bright and doesn"t need to be powered-on at night, so let"s put it to sleep until we wake up. Edit cron as root: sudo crontab -e Select nano as an editor by pressing the 2 key. Adafruit Industries Page 21 of 27

22 Scroll beneath the commented text (#) and enter the following: # PADD Sleep # Turn off the PiTFT+ at midnight * * * sh -c "echo "0" > /sys/class/backlight/soc\:backlight/brightness" # Turn on the PiTFT+ at 8:00 am * * * sh -c "echo "1" > /sys/class/backlight/soc\:backlight/brightness" Save (control+o) the configuration and exit (control+x) nano to be brought back to the terminal. Reboot the Pi to apply the new changes by running: sudo reboot When your Pi reboots, the TFT should boot into PADD: Adafruit Industries Page 22 of 27

I purchased this kit for the Raspberry Pi, the LCD screen just connects to the Raspberry Pi GPIO pins. It has a Adafruit LCD screen and a case for my Raspberry Pi 3B+

When my Samsung SD card died I had to re-setup a new SD card but the IP address came across as the mac address stayed the same (as it was the same hardware), I did, however, change the name of the Static IP hostname in my home router to match the new name “raspberrypihole” (not “pihole”)

Before I add computers on my network to the PiHole I had better uninstall the nextdns.io (my blog post about NextDNS.io here) as the Pi will now be the main DNS blocking Sinkhole in our house.

After 20 hours or rining computers through the Pi-Hole Admin interface I loaded the PiHole Admin Interface (at http://192.168.0.201/admin/index.php) was reporting stats.

the github LCD_Show script works well enough to get this LCD working on the Raspberry Pi 4 using the latest (at the time of this writing) release named Buster... what is not configured is the touchscreen coordinates, nor a very important configuration: right-click on a touchscreen...

- install the xinput-calibrator package, then run the program from either the desktop menu (Preferences) or from the command line of a terminal window; You"ll be shown a graphical screen, and asked to pen touch four different points on the display. When done you"ll be presented with a line of values representing your LCD"s touch boundaries, such as: "258 3966 3774 226" - Enter these values (as root) into the file 99-calibration.conf under the /etc/X11/xorg.conf.d directory, then reboot your RPi to enjoy more accuracy
