You can make a square wave relaxation oscilator with a CMOS Schmidt Trigger inverter such as a 74AHC1G14, one resistor, and one capacitor. Consult the data sheet to find the UTP and the LTP. These are the upper threshold point and the lower threshold point. Now use the equation for an RC charging discharging circuit to compute how long takes to charge the capacitor up to V=UTP with an initial condition of V=LTP, and discharge the capacitor down to V=LTP with an initial condition of V=UTP.Originally posted by maniza_201@Mar 1 2006, 05:39 AM
