salut
je suis un debutant en arduino et j’ai un petit projet a realiser c’est transeformer un jouet tractopelle en RC . POUR ça je besoin de 2 module transmittion nrf24l01, un pont H l293 , 3 joystik ,2 petit servomoteur ,et un dc moteur ,et en cherchant sur la toile je trouver un code pour ça mais le probleme que le code trouvé manque le servomoteur .
donc est ce que il y a quelqu’un qui peut m’aider a ajouter la commande servo dans le code sachant que je essayer pas mal de fois mais j’arrive pas .
voici le code tx
