+Deze metingen zijn gedaan met een voedingsspanning van \SI{5.00}{\volt}, een
+weerstandwaarde van \SI{218.8}{\kilo\ohm}, en een condensator van
+\SI{10.4}{\nano\farad}.
+
 Uit deze tabel is te zien dat de frequentie tussen \SI{174.6}{\hertz} en
 \SI{523.3}{\hertz} moet kunnen vari\"eren. <hier een stuk over hoe je die spanningen
 berekent ofzo>. Omdat er een weerstandsladder gebruikt word voor het keyboard, moet
