The following arduino sketch toggles 17 LEDs attached to the Arduino Pro Mini by pressing 6 (DCC address) on DCC controller, followed by function button and number that will toggle each LED independently. At the same time, we record the number of milliseconds that have passed since the Arduino started. The router then replies with a number, the number represents the count of octets that have been sent or received. The code sends an SNMP get-request to the router. You will need to edit #define This_Decoder_Address 6 as this sets DCC address of Arduino DCC decoder to an address of your choice. Octets per second (Result from speed test in Mbps 1048576) / 8. Unzip it and move it to your Arduino libraries folder, usually found in My Documents/Arduino/libraries. The software for a DCC decoder is remarkably simple thanks to NmraDcc DCC library. Do not change this pin or your DCC decoder will not work. This pin provides the hardware interrupt mechanism that is used bye Arduino DCC data decoding library. Arduino Code / Keyboard test For the Arduino Leonardo, Micro or Due Reads a byte from the serial port, sends a keystroke back. Copy and paste the keypad library file inside the file with the name ‘libraries’ highlighted with yellow color. Connect the capacitor to one end of the intersection and the other end to the ground rail. Notes You must include the keypad library in your Arduino library file. Then connect the 10K resistor to the +ve rail and the 150K resistor to the intersection of Pin2 and Pin6. The output of the opto-coupler is connected to Arduino pin 2. Let's start by connecting the pins of the 555 timer IC.Connect Pin-1 to ground. ![]() A slow opto-coupler could distort this timing. The 6N137 is a fast opto-coupler that is necessary because DCC decoding relies on measuring pulse width where 50µs represents 1 and 100µs represents 0. We use rectifier and LM7805 regulator to convert it to 5V (DC) that can safely power Arduino DCC decoder. The DCC signal is an alternating voltage (AC) usually 16V, depending on your DCC controller.
