This is my first time in this forum, my name is oscar from Spain and i'm doing a project with arduino + visual basic. Until now already have developed the program of vb but i'm not sure how make the arduino program, my project is with 5 temperature probe pt100( already have the arduino code) send to vb and from vb send to arduino some parameters in the same time like set point etc. This is possible? I think i should be string of characters first the probe and some alarms right? How many data is possible to send in the same time?
My hw is arduino mega.
