FK243

MINI ORGAN 13 TONE

Categories : Other Sound

This mini organ circuit generates 13 different tones by selecting between conductive electrodes with a stylus of conductive wand. A supplied, 8 Ohm 0.25W speaker acts as an efficient audio output device. The tone setting resistors are readily accessible for class room study of the effect of component values on the frequency of an oscillator. The FK243 utilizes the versatility of the LM555 timer as both tone generator and audio driver.
