Code.Ino is an educational digital game, developed for the mobile platform. The main objective is to be an auxiliary tool in the teaching-learning process of Arduino programming for high school and elementary school students. Thus, the proposal is for the player to learn, in each phase of the game, in a creative and playful way, the components of an Arduino board and the logic involved in data processing. In the last phase of the game, the player must be able to implement a complete project based on the knowledge obtained throughout the phases. As a consequence, it is expected that the Code.Ino game, when used as a support tool in programming classes, will optimize the programming teaching-learning process in primary schools.
