IC1　CD4066 quad bilateral switchC1　 0.1-μF capacitorRI 10-kΩ, 1/4-W 5% resistorR2 4.7-kΩ, 1/4-W 5% resistorR3 2.2-kΩ, 1/4-W 5% resistorR4 1-kΩ, 1/4-W 5% resistorR5 1-MΩ, 1/4-W 5% resistor A programmable resistor can replace a potentiometer or fixed resistor. Remember that the ON resistance of IC1 might have to be taken into account in some applications.
