Description

initiation au langage circuitpython et a la puce nrf52840 e bookLe langage de programmation Python est apprci par les pdagogues parce que sa syntaxe le rend facile comprendre. Il s'est galement impos chez les informaticiens expriments. La socit Adafruit a dvelopp une version spciale de Python pour l'embarquer sur les microcontrleurs 32 bits : CircuitPython. Ce livre permettra au lecteur de s'initier la programmation en CircuitPython sur deux cartes : Feather BlueFruit Sense (galement appele Feather nRF52840 Sense)

Le langage de programmation Python est apprécié par les pédagogues parce que sa syntaxe le rend facile à comprendre. Il s'est également imposé chez les informaticiens expérimentés. La société Adafruit a développé une version spéciale de Python pour l'embarquer sur les microcontrôleurs à 32 bits : CircuitPython.

Ce livre permettra au lecteur de s'initier à la programmation en CircuitPython sur deux cartes : Feather BlueFruit Sense (également appelée Feather nRF52840 Sense) et CLUE nRF52840 Express. Chacune est animée par le SoC nRF52840 de NORDIC avec une architecture à 32 bits.

Pour ce voyage dans le monde de la programmation embarquée, l'auteur sort du chemin classique, à savoir un cours complet sur la programmation orientée objet appliquée à ce langage. Il préfère emmener le lecteur directement sur le terrain avec des projets qui mettent en oeuvre les cartes et différents périphériques. Plus d'une quarantaine d'exemples et de montages permettent de découvrir la richesse de CircuitPython. Toutefois l'auteur s'est imposé une limite pour ne pas décourager les novices : le code de chaque projet ne dépasse jamais la centaine de lignes. Pour ce qui est du matériel, là aussi la simplicité domine : aucun programmateur, un simple PC suffit ; aucun soudage grâce au câblage sur platine d'essai. Les cartes d'extension FeatherWing à enficher sur la Feather nRF52840 Sense permettent de démultiplier ses fonctions : matrice de LED, enregistreur de données, écran à encre électronique, écran OLED, écran TFT, commande de moteurs, audio, relais…

Toutes les étapes (assemblage des différents composants, installation des bibliothèques requises, programmation, tests…) sont expliquées en détail. Le code des différents exemples et projets est disponible sur Github. Le résultat de chaque projet est même présenté sur de courtes vidéos disponibles sur YouTube.

À la fin de sa lecture, le nouveau Pythonien pourra facilement approfondir les notions abordées et donner vie à ses propres projets grâce aux outils qu'il aura essayés.

Ce livre s'adresse aux lycéens et étudiants ainsi qu'à toute la communauté des makers.

I would buy this twice!
Style: Sport, Size: 12in
This Chuckit! Dog Ball Launcher 12M Sport is the perfect product for the dog park! It makes games of fetch so much easier and more fun — the long handle gives great reach, so I can launch balls super far without even bending over, and our dog goes absolutely wild chasing them. It’s comfortable to hold, works smoothly with 2.5" dog balls, and really saves your arm and back if you’re doing a lot of throwing. The design is sturdy and reliable, so we can play for longer without worrying about it snapping or wearing out. If you spend time at the dog park or love playing fetch, this launcher turns a regular game into something even better — our pup gets twice the exercise and we get to enjoy every minute of playtime!

Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

Perfect for offseason beach days
Winter in New England can be tough for a myriad of reasons, one being the difficulty in ensuring your high energy Labrador retriever is expelling enough energy and not climbing the walls. Luckily, this dreary time of year also means the beaches are open to dogs, and this toy is the perfect tool to make sure your furry friend gets their steps in. It is pretty easy to use and not too large for toting to the beach as it folds in half. The thrower itself is sturdy, although the included ball is a bit flimsy. Backup tennis balls are definitely recommend for public areas anyway. Once you’re done, you can bang or brush the sand right off for easy cleanup as needed. If you have kids, you get double bag for your buck because you can have them take turns throwing the ball or chasing as well. Definitely worth it’s value to tire everyone out and have some fun doing it.

Thrower great, ball not so much
Our german shepherd dog really loves this fetch thrower. I appreciate the fact that it can be folded when not in use, which makes it a lot more practical to store. Once you get the hang of it, you can chuck balls REALLY far, and with pretty great accuracy too. I am deducting one star because I feel like the included tennis ball is just, trash. It's already broken and we've only been playing with this toy for a couple of weeks, and not for very long at a time. We will be purchasing new tennis balls to continue to play with the launcher though. Overall it's a solid toy and our dog really enjoys playtime with it.
