There was two aspects to the hardware. If you’re planning on manipulating that string with functions like parseInt(), split() and other string handling functions, make sure to get the string out of the array first. Introduction Serial communications provide an easy and flexible way for your Arduino board to interact with your computer and other devices. Arduino IDE in the Cloud. The dim state shows that the code is constantly sending and receiving data in the main program (LED3) and that it is also spending some time in both of the serial interrupt routines (LED1 and LED2). The last iteration of Lumi was written in Windows Universal Apps SDK. Both the MEGA 2560 and Due have 4 serial ports in total.
