+## Function Examples
+
+### Battery
+[battery.py](battery.py)
+
+An example of how to read the battery voltage and display a battery level indicator.
+
+### Button Test
+[button_test.py](button_test.py)
+
+An example of how to read Badger2040's buttons and display a unique message for each.
+
+### LED
+[led.py](led.py)
+
+Blinks Badger's LED on and off.
+
+### Pin interrupt
+[pin_interrupt.py](pin_interrupt.py)
+
+An example of drawing text and graphics and using the buttons.
+
+## Application Examples
+
+### Badge
+[badge.py](badge.py)
+
+Create your own name badge! This application looks for two files on your MicroPython drive:
+* `badge.txt` - A text file containing 6 lines, corresponding to the 6 different pieces of text on the badge
+* `badge-image.bin` - A 108x128px 1-bit colour depth image to display alongside the text. You can use `examples/badger2040/image_converter/convert.py` to convert them:
+
+```shell
+python3 convert.py --binary --resize image_file_1.png image_file_2.png image_file_3.png
+```
+
+### Checklist
+[list.py](list.py)
+
+A checklist application, letting you navigate through items and tick each of them off.
+
+### Clock
+[clock.py](clock.py)
+
+A simple clock showing the time and date, that uses the E Ink's fast speed to update every second
+
+### E-Book
+[ebook.py](ebook.py)
+
+A mini text file e-reader. Comes pre-loaded with an excerpt of The Wind In the Willows.
+
+### Fonts
+[fonts.py](fonts.py)
+
+A demonstration of the various fonts that can be used in your programs.
+
+### Image
+[image.py](image.py)
+
+An image gallery. Displays and lets you cycle through any images stored within the MicroPython device's `/images` directory. Images must be 296x128 pixels with 1-bit colour depth. You can use `examples/badger2040/image_converter/convert.py` to convert them:
+
+```shell
+python3 convert.py --binary --resize image_file_1.png image_file_2.png image_file_3.png
+```
+
+### QR gen
+[qrgen.py](qrgen.py)
+
+This application looks for a file on your MicroPython drive:
+- `qrcode.txt` - A text file containing 9 lines. The first line should be a URL which will be converted into and displayed as a QR code. Up to 8 more lines of information can be added, which will be shown as plain text to the right of the QR code.
+
+### Launcher
+[launcher.py](launcher.py)
+
+A launcher-style application, that provide a menu of other applications that can be loaded, as well as information such as battery level.

+
+https://discourse.pi-hole.net/t/how-do-i-use-pi-holes-built-in-dhcp-server-and-why-would-i-want-to/3026
+
+> Some routers (and even some Internet Service Providers) do not let you change these settings. In this case, using Pi-hole’s DHCP server is very advantageous because you can still get automatic, network-wide ad ad blocking even if you can’t make the necessary changes on existing hardware.
+
+
+
+
+> Bonjour messieurs, j'infirme ce qui a été dit avant, on peut changer les DNS de la livebox mais il faut désactiver le serveur DHCP de la box.
+>
+> Par exemple, j'utilise Pi-hole sur un ubuntu (rasperry pi fera l'affaire), sur ce pi-hole j'ai activé le serveur dhcp pi-hole , qui distribue les adresses DNS, et fait office de DNS avec débordements sur celles d'Orange mais j'aurai déborder vers google aussi.
+>
+> En méthodologie, il faut activer d'abord le dhcp de la livebox et ainsi fixer l'adresse IP de la livebox (pour moi 10.0.0.1), j'affecte ensuite une ip fixe sur le rasperri pi-hole , puis je désactive le dhcp livebox et enfin j'active celui du rasperry pi-hole avec passerelle sur le 10.0.0.1. J'ajoute un DNS secondary dans les fichiers config pihole et je mets la livebox , au cas où le rasperry ait un souci de ralentissement important.
+
+https://mediacenterz.com/tutoriel-complete-pi-hole-bloqueur-dannonces-pour-toute-la-maison/ :
+
+> Pour bloquer les annonces au niveau du réseau, ce qui signifie que tous les appareils connectés à votre réseau domestique ne verront aucune annonce, vous devrez modifier manuellement les adresses IP de votre serveur DNS sur votre routeur. Alors que de nombreux routeurs autorisent la configuration manuelle des serveurs DNS, certains ne rendent pas cette option avancée disponible. Les micrologiciels de routeur personnalisés, tels que DD-WRT, OpenWRT et Tomato, permettent d’ouvrir cette option parmi d’autres. Par conséquent, si vous ne voyez pas d’option permettant de modifier les serveurs de noms DNS, envisagez de passer à l’un des microprogrammes de routeur de remplacement gratuit pris en charge.
+>
+>L’avantage ici est qu’il n’y a qu’un seul endroit où vous aurez besoin de mettre à jour l’adresse IP de votre serveur DNS au lieu de chaque appareil. Cependant, il y a quelques inconvénients:
+>
+>Le suivi par hôte sera indisponible. Toutes les demandes adressées à PiHole apparaîtront comme si elles venaient de votre routeur. Mon opinion personnelle est que ce n’est pas un gros problème pour un utilisateur domestique typique. Je ne l’utilise pas. Mais si vous en avez absolument besoin
+Vous ne pourrez pas vous connecter aux périphériques avec leurs noms d’hôte car PiHole ne peut pas résoudre les noms d’hôte. Encore une fois, pas un gros problème pour un utilisateur à domicile typique à mon avis.
+Si les deux inconvénients ci-dessus sont des pactes pour vous, vous pouvez les surmonter partiellement en utilisant le fichier PiHole Hosts ou en publiant complètement l’adresse IP de PiHole via Dnsmasq dans un routeur (si cette fonction est prise en charge).
+>
+>Notez que si vous choisissez cette méthode, vous devrez renouveler les baux DHCP fournis par le routeur. Pour ce faire, le plus simple consiste à redémarrer le routeur.
