Once the board has read the input, make it print this information back to the computer as a decimal value. You can do this with the commandSerial.println() in our last line of code: 一旦板子读取了输入,将此值通过电脑作为 decimal 值打印。可以通过Serial.println() 命令实现: Serial.println(s...
read by Processing, PD, Max/MSP, or any other program capable of reading data from a serial port. The Processing code below graphs the data received so you can see the value of the analog input changing over time. 可以通过 Arduino串口监视器来查看发送的数据,或者任何可以读取串口数据的软件,例...
