Voor thuis en op school Dit boekje is gericht op leerlingen en natuurkunde docenten in het voortgezet onderwijs. Met voorbeelden op verschillende gebieden van de fysica, geeft het aan hoe een populair microprocessor platform als Arduino toegepast kan worden in het natuurkunde practicum. We passen Arduino onder andere toe als nauwkeurig meetinstrument, zodat metingen uitgewerkt kunnen worden in een spread sheet. Hoewel enige handigheid niet overbodig is, kunnen de beschreven experimenten kunnen ook uitstekend thuis worden uitgevoerd. In dat opzicht wil dit boek met name bij de jeugd de interesse wekken voor de toepassing van microprocessoren. In de hobbysfeer is dat niet alleen een zinvolle tijdsbesteding, maar bovenal interessant en leuk. Veiligheid staat uiteraard voorop bij het doen van experimenten. Energie, licht en warmte zijn onuitputtelijke bronnen, maar ze kunnen ook gevaar opleveren. Voor dit boek geldt dan ook het motto: Eerst denken, dan doen.

Dit is een ideaal boek voor hobbyisten, studenten en ingenieurs die op een leuke manier C en het gebruik van een mbed ARM microcontroller willen leren, rechtstreeks op internet zonder ingewikkelde software-installatie. De projecten in dit boek zijn bedoeld voor gevorderden op het gebied van ARM microcontrollers of de programmeertaal C. Dat wil zeggen dat de kennis uit deel 1 van deze serie bekend verondersteld wordt. Cloud technologie De in dit boek gebruikte mbed NXP LPC1768 maakt gebruik van cloud-technologie, een revolutionair concept voor software-ontwikkeling. Dit houdt in dat u geen software hoeft te installeren om de mbed te kunnen programmeren! Het enige dat u nodig heeft, is een internet-browser zoals Microsoft Internet Explorer, en een USB-poort op uw PC. U kunt vanaf elke willekeurige PC waar dan ook ter wereld toegang krijgen tot uw project en er aan verder werken. Wanneer u klaar bent, kunt u met een paar eenvoudige klikjes met uw muis het programma overzetten naar uw mbed-hardware. Uiteraard kunt u de projecten ook downloaden en op uw eigen PC opslaan wanneer u dat liever heeft. In een deel van de projecten wordt Visual Basic gebruikt; dit gratis pakket is nog niet in de cloud beschikbaar en moet wel op uw PC geïnstalleerd worden. Onderwerpen die aan de orde komen Leer het programmeren van een ARM microcontroller via cloud-technologie. Geen ARM ontwikkelsoftware-installatie op uw eigen PC. Leer hoe u een ARM microcontroller met internet kunt verbinden, hoe u via internet uw ARM kunt bedienen en hoe u vanaf de ARM microcontroller tweets kunt versturen. Leer hoe u een CMUcam camera kunt aansturen en toepassen in uw applicaties, bijvoorbeeld als alarm. Leer hoe u met behulp van de gratis PC programmeertaal Visual Basic met uw ARM microcontroller kunt communiceren met gebruik van multi-threading. Voorbeelden van projecten in dit boek: internet-server, automatisch twitteren, digitaal naar analoog conversie, USB HID, automatisch metingen in een spreadsheet plaatsen, met een camera bewegingen waarnemen, seriële communicatie met een zelfgeschreven PC-programma, gebruik van een LCD en SPI en I²C communicatie.

En moins de 100 lignes de code par projet avec les cartes Feather Sense et Clue Express d'Adafruit 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. Chaîne YouTube de l'auteur : YouTube (Michaël Bottin)
