“An op-amp astable multivibrator with a 15 V supply, a 10 kΩ resistor from the non-inverting input to ground, a 10 kΩ feedback resistor from output to the non-inverting input, and a 10 kΩ resistor plus 100 nF capacitor timing network at the inverting input.”
次はこちらChange the timing capacitor to 1 µF.Add an output LED with a series resistor.
