0x480 Arduino VGA - in 8 Colors! Steps and a Guide - DQYDJ


If the pin isn’t connected to anything, digitalRead() can return either HIGH or LOW (and this can change randomly). The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini’s A6 and A7 pins, which can only be used as analog inputs.

MCP23017 - i2c 16 input/output port expander ID: 732 - $2

The function used to output a PWM signal is analogWrite(pin, value). pin is the pin number used for the PWM output. value is a number proportional to the duty cycle of the signal. When value = 0, the signal is always off. When value = 255, the signal is always on. On most Arduino boards, the PWM function is available on pins 3, 5, 6, 9, 10, and 11.

2/1/2016so the master will output 255 and box A will take that and subtract an amount (let's say 10) and will output 245 and so on. if another pin will show a higher value, it will override and the output will be the higher value minus 10.

If you want to write sensor data directly to a file on your computer without having to copy and paste the output form the serial monitor window, then try reading the data stream directly from the serial port (which is what the serial monitor does anyway, I suspect).
