Display a Random Number on the NeuroMaker Hand
Welcome to programming the NeuroMaker Hand using C++ programming! In this project, we are going to build different functions that allow us to present different random number gestures using the NeuroMaker Hand.
Temps estimé
Approximately 1 hour
Nombre de personnes
1 à 4 étudiants pour chaque main NeuroMaker disponible
Fournitures nécessaires
- Une main NeuroMaker entièrement construite
- Un ordinateur MacOS, Windows ou Chrome OS
- Éditeur en ligne Arduino avec Arduino Create Agent entièrement installé
Fichiers de programme nécessaires
- Veuillez consulter la répartition du code dans les instructions ci-dessous
Les préparatifs
- Veuillez vous assurer que la main NeuroMaker dispose de piles fonctionnelles. Des voyants d'alimentation supplémentaires sur la carte d'alimentation de la main doivent s'allumer lorsque l'interrupteur marche/arrêt a été activé. Si vos doigts bougent de manière erratique ou ne bougent pas du tout après avoir téléchargé le code ci-dessous, cela peut signifier que vos piles sont faibles.
- Veuillez vous assurer que l'agent de création Arduino et l'éditeur en ligne Arduino sont répertoriés en toute sécurité sur le pare-feu de votre district. Les instructions pour le personnel informatique sont fournies ici : Guide de référencement sécurisé de l'éditeur Arduino
- Si vous n'avez pas encore installé l'éditeur Arduino, veuillez terminer le projet de configuration de l'environnement de codage C++
Arrière plan
With the five digits on our hand, we can conduct simple number communication. Hold up a pointer finger and we can non-verbally present a number one. Hold up two fingers a two, three fingers a three, etc. This sound easy enough with our new programming skills. However just like building custom functions, writing out a series of if statements or hard to follow logic can also get tedious. Thankfully we can now introduce switch case statements! Following the instructions below you will see how you can introduce a series of situations that you can call on command instead of filling your programming screen with tons of if statements. Let’s take a look!
