Most dimmers use pulse width modulation (PWM) to control the amount of power that is delivered to the lamp. Those that come bundled with a switch faceplate control the firing angle of a Triac on the 240V mains side. These work fine with resistive loads but....

The 555 timer will put out positive pulses. The pulse width is inversely proportional to the difference in voltage between the voltage at "ANALOG IN" and the voltage of the 4. 7uF capacitor(let`s say 2. 5 volts). To calibrate this circuit, hook it up to a....

The output of this circuit should be fed into a high-impedance load, say >100K, remembering that the impedance of C4 is around 3K. A PNP transistor can also be used, with the necessary changes to the supply voltage. An op-amp can also be used, connected as....

It can`t be 0 volts, since the current does not freely move around, due to the resistor; resulting in one side being more negatively charged, and the other more positively charged, since the electrons can move faster to an end of the battery than through the....

It says that D1 compensates for D2`s forward drop by providing 0. 6V of bias. Is the +5V an external 5v source How does it compensate The R1, R3 and D1 basically creates a 0. 6V bias on the other side of the capacitor, so that a positive swing in the signal....
