Investigating potential power current sources capable of handling both AC and DC currents using the LM317 current source.

As usual for Circuit VR, we’ll be simulating the designs ... Notice that here, I’m using a Spice voltage source for the input voltage and a pulse generator to create PWM.

There are better portamento circuits out there, but they’ll probably involve op-amps. As a quick aside, you can make a rudimentary keyboard with just a bunch of push buttons and voltage sources.

An ultra-low power sensor operates using energy harvesting from various sources for efficient monitoring. The oscillator ...

are electronic components that can be used to regulate the voltage in circuits and to make logic gates. Light-emitting diodes (LEDs) give off light and are often used for indicator lights in ...

The circuit of a voltage divider may be drawn with the two resistors vertical, not horizontal. If there are two resistors in series across a voltage source, then the circuit is a voltage divider.
