![]() I'll certainly look into I2C communication.įor connecting to different panels, you might want to consider using RJ-45 cat 5/6 (ethernet) cables to bring multiple wires to each panel. But if, say, I use only one of them, then, how long can the wires be, to still get the signal from the pressed button (I guess it depends on the resistance of the wire, isn't it?)? ![]() I thought of placing different control panels in different places, and thus needed a lot of arduinos. Radman, you might be right, I'll rethink the concept. However, I read somewhere that Arduino Uno can only establish one serial connection at a time (be it a virtual port or not). At the same time, the board itself has some pins, labled tx / rx - so, may be, I can connect it to the other board AND to computer. Now that I come think of it, may be I am wrong, I am using a usb cable to link arduino to the laptop with Processing. At the asme time - to communicate between Processing and Arduino I also need a serial port (arduino uno has only one) 2-3 arduino UNO boards be connected via serial ports to the arduino Mega board (it is said to have 3-4 separate serial ports - thus I am thinking of connecting 2-4 arduinios to it), in such case only the serial wires must be long.ģ*) I would also like to have a separate screen run for each conrol panel.several switches/buttons be all connected to one board (in this case some of the wires will stretch for a meter/a meter and a half, to get connected to the main panel). ![]() My next step is to create a more sophisticated mathematical model for a bigger ship, but in order for a number of people to operate it - I need to decide on the following: I have already made a small panel with a number of buttons and switches, which controls a small ship on the screen (you can steer it, and do some other, minor things as well). I am planning to build a spaceship control panel, which will control a software spaceship programed in Processing. ![]()
