  • Page 11 General information ANALOGUE OUTPUTS (PWM): SK10 SK11 SK12 SK13 SK14 Lines 3, 5 and 6 can be configured as analogue output (PWM, +5 V). With a value between 0 and 255, the duty cycle can vary between 0 and 100 %. Attention: The LED will have an inverse logic in this mode: 0 % duty cycle = LED on, 100 % duty cycle = LED off. All digital inputs have a common ground (GND).

    Leds and how to use them Leds feature a specific voltage Never connect leds in parallel drop, depending on type and colour. Check the datasheet for exact voltage drop and rated current ! How to Calculate the series resistor: Example: operate a red led (1.7V) on a 9Vdc source. Required led current for full brightness: 5mA (this can be found in the datasheet of the led) Supply voltage (V) - led voltage (V) = series resistance (ohms)
