Reading Time: 16 minutesIntroduction to Diodes A diode is a two-terminal electronic component that allows electric current to flow in only one direction. You can think of a diode as almost like being a check valve for electrical current. Like a check valve for plumbing permits water to flow in one direction, but not the other — the […]

Reading Time: 9 minutesWhat Is an LED? The simple answer is that an LED is a type of light. It’s also a type of diode. The acronym LED stands for Light Emitting Diode. Just as a diode is a semiconductor, an LED uses semiconductor properties to allow it to illuminate – unlike an incandescent light which uses a […]
Reading Time: 11 minutesA switch in electronics is a device or component that completes a circuit electrically. Electronic Switches An electronic switch is a switch that has no physical contacts or moving parts — like an electromechanical switch — that is operated by electric signals within a circuit. Electric switches are strictly controlled by active electronic components within […]
Reading Time: 6 minutesA multimeter is a testing device that measures electrical properties and provides readouts of values pertaining to the electrical property being measured. The multimeter is a tool used by hobbyists, by those in the electrical and electronics industry, and by people in other industries — where measurements of electrical properties such as voltage, current and […]
