Update ! PCB is finish for test !

Software: Neopixel control was implemented ! (up to 8-RGB-LED's)

ELWMS 2.0, the multitool with new hardware and additional functions: - Buzzer was added for sound indication (High, low) - Higher output frequency up to 4 Mhz - USB-Uart (transmission of measurement data, firmware upload) - 3 push-buttons - Voltage measurement up to 15 VDC - Servo-Out (1-2ms signal to control servos, controlled by push-buttons) - Toggle-Out (High/Low controlled by push-buttons) - DCF 77 decoding - NMEA decoding And more could follow... -difference voltage measurement/hold function -neopixel controling -DS1820 temperature decoding if detected in 1-wire mode
