Trusted teacher: ARDUINO is a free hardware microcontroller. It is very useful for learning electronics and coding at the same time. It is very estimating thanks to that we can solve problems and look at the results physically. Thanks to the size of its community and the openness of its philosophy, information is widely accessible. Arduino allows us to undertake countless projects of all kinds. In a way, it's a small door through which you can easily access the world of makers. Among others. In the particular case of the arduino, my main goal is to stimulate creativity and curiosity. In addition to allowing my student to acquire a level of competence which allows him to function alone. I am used to working with people of different ages. I believe in segmentation, visualization of progress, objective results and practice. Beyond these general lines, there is no rule or magic method. Some things work with some students and not with others. Adapting to needs is really the goal of private lessons. So I will do my best to find what motivates and helps my student.
