Hi everyone, I really need your help. And I can’t figure out how to force the network port to appear in the list. The caveat is that at any given time, only one of these ports can actively receive data. Many articles are written about this subject all around the internet, but I have not found any of them that could help to create a “real world” and usable application, so I am going to show you my way of dealing with this task. There are many relay boards available, each with some sort of driver device to protect the Arduino's outputs. (Note this would only work with 1 connected Arduino, extra programming would be required for multiple devices) If it’s “OK” then we set a global variable comPort and connected, so that we can use them elsewhere in the program. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Ever wanted to use any pair of pins for I2C on Arduino, not just the dedicated pins on Analog 4 & 5? Me too, so I made a quick little Arduino library called “SoftI2CMaster”, available in the “blinkm-projects” Googlecode repository. Hardware. Several data from arduino to processing. You will need three LEDs, jumper wires, breadboard, and Arduino. There is significantly less documentation on how best to read a PWM signal. So I want to use one of the other 3 serial ports.
