+ | This LFO has the following characteristics : | ||
+ | * Output swing from 0 to 4.8V | ||
+ | * Frequency from 0.5 to 10Hz | ||
+ | * Faded LED to visualise the LFO State | ||
+ | * Reset on the rising edge of a 5V Gate signal | ||
+ | * Low component count | ||
==== Schematic ==== | ==== Schematic ==== | ||
+ | The LFO is based on an ATTiny45/85 microcontroller. | ||

+ | * Analog Input on Pin 3 reads the " | ||
+ | * Triangle Waveform LFO Waveform is generated by the Microcontroller | ||
+ | * LFO Output on Pin 5 (PWM Fast Mode) is filtered by R1/C1 to generate the 0-5V peak Triangle output | ||
+ | * AMP control potentiometer controls the amplitude of the LFO Output | ||
+ | * LED brightness is controlled by PWM as well | ||
