What are Diodes and How Do I Use Them?

By | 2017-07-25T15:13:36+00:00 July 19th, 2017|0 Comments

Through-Hole Diode   A diode is an electrical component that behaves like a one-way valve. It allows current to flow through in the forward direction but does not allow current to flow through it backward. The diode symbol has a triangle that can be viewed as an arrow that denotes the direction of [...]

What are Microcontrollers, and How Do I Use Them?

By | 2017-07-25T15:10:18+00:00 July 14th, 2017|0 Comments

An ATMEGA32u4 on an Arduino Leonardo Microcontroller units (MCUs) are small systems on a chip (SOC) that include a computer processor, memory to store instructions (program code) and data, and I/O peripherals for communication, measurement, and control. The user writes program code which is then compiled into machine code and loaded into the [...]

What are Inductors, and How Do I Use Them?

By | 2017-07-19T12:55:10+00:00 July 13th, 2017|0 Comments

Several inductors next to a penny for scale. An inductor is an electrical device that stores energy and resists changes in current flow. This ability to store energy and resist current is measured in a unit called inductance. As current flows through an inductor, a magnetic field builds inside the component. The magnetic field [...]

What are Capacitors, and How Do I Use Them?

By | 2017-07-17T20:11:09+00:00 July 5th, 2017|0 Comments

Through-Hole Capacitors A capacitor is an electrical component that stores energy as an electric field. A capacitor is constructed with two plates, very close together, with an electrical insulator between them. As a voltage is applied to the plates, an electrical field builds between them. While the field builds, current runs through the [...]

What are Resistors, and How Do I Use Them?

By | 2017-07-25T14:58:33+00:00 June 30th, 2017|0 Comments

Through-Hole Resistors A resistor is an electrical component with a controlled resistance. Resistance is the electrical property that resists the flow of electricity and is measured in the unit "Ohms", which is denoted by the capital Greek letter Omega (Ω). The higher the resistance, the less current flows through the resistor with the same voltage. This [...]

Tuning Adjustable Analog and Digital Sensors

By | 2017-06-09T14:43:08+00:00 June 9th, 2017|0 Comments

Many of the sensors we supply have amplifier circuitry (op-amp) built right into the sensor. This circuitry can be adjusted with the potentiometer. Adjusting this will either change the trigger level (digital output) or it will change the amplification of an analog signal. You can adjust the potentiometers using a small screwdriver. Adjustable Digital Sensors [...]
