Stimmmopped is AVR ATmega8-based project that will assists you in tuning your string instrument to a given tone. It utilizes the stroboscopic effect to give feedback about the adjustment of your instrument. When the frequency that you chose has tone then the two LEDs on the board blink. Two lines are projected at a fixed position on the string when the string vibrates with the correct frequency. If frequencies don't match, the lines appear to be blinking or moving to the observer's eye. The moving or blinking effect decreases with decreasing difference between the two frequencies.
