PC arduino using a 0-255 rocker output analog data, through a serial port transmission to another arduino on board, and then output to the led, brightness control, their experiment, is the next bit machine receive less than the upper machine data, very upset, bosses teaching, hard to realize the free, novice worship,

Digression: I also play the arduino before, but later found to control the content of too little, cruel time turn STM32, is to spend time, suggest you also consider, is more difficult than arduimo to fit, but after two or three months to fit, not the same, plastic toy gun, become a rifle, can on the battlefield,

Eldest brother, now also play a arduino, can help achieve this function, hard hard

CodePudding user response:

Three years didn't go with the arduino,
UART operation is very simple, you write down all possible factors in paper, then each screen up

CodePudding user response:

Your problem is mainly a serial port communication, check the attachment, best to otherwise it's hard to say,
