+ | ==== Voltage In ==== | ||
+ | Any voltage between 0-5V at the VIN pin can control the frequency. Without input resistor the potentiometer wont have any effect on the frequency. But depending on the value of the input resistor the potentiometer will change the frequency, too. | ||

+ | ==== Sync ==== | ||
+ | |||
+ | For the Sync input one can use any 0-5V source, but a diode is needed . An additional resistor can decrease the power of the syncing signal.\\ | ||
