### Electronics Projects: How to Build Series and Parallel Circuits

Whenever you have circuits that consist of more than one electronic component, those electronic components must be linked together. The two ways to connect components in a circuit are in series and in

### Electronics Components: Integrated Circuits and Moore’s Law

You've probably heard of Moore’s law, an electronics statement which in a nutshell predicts that the number of transistors that can be placed on a single integrated circuit doubles about every two years

### Electronics Components: What Exactly Is an Integrated Circuit?

An integrated circuit (also called an IC or just a chip) is an entire electronic circuit consisting of multiple individual components such as transistors, diodes, resistors, capacitors, and the conductive

### Electronics Components: How Integrated Circuits Are Made

You don’t have to know how integrated circuits (IC) are made to use them in your electronics projects, but the process is pretty interesting The process is complex and varies depending on the type of chip

### Electronics Components: Integrated Circuit Packages

Integrated circuits (ICs) come in a variety of different package types, but nearly all of the ICs you'll work with in hobby electronics come in a type of package called

### Electronics Components: Control the Time Intervals in an Astable 555 Circuit

An astable 555 timer circuit in an electronic project works like a metronome: It keeps running until you turn it off. This mode is also called oscillator mode

### Electronics Components: The 555 in Astable (Oscillator) Mode

Another common way to use a 555 timer is in astable mode. The term astable simply means that the 555 has no stable state: Just as it gets settled into one state

### Electronics Components: Calculate the Duty Cycle of an Astable 555 Circuit

The astable mode is also called oscillator mode, because it uses the 555 as an oscillator within an electronic circuit. Astable mode creates a square wave signal.

### Electronics Components: The 555 in Bistable (Flip-Flop) Mode

A flip-flop is an electronic circuit that alternates between two output states. In a flip-flop, a short pulse on the trigger causes the output to go high and stay high, even after the trigger pulse ends

### Electronics Components: How to Use the 555 Timer Output

The output pin (pin 3) of an electronic 555 timer circuit can be in one of two states: high and low. In the high state, the voltage at the pin is close to the supply voltage. The low state is 0 V.

### Electronics Components: Double Up with the 556 Dual Timer

It turns out that there are many uses for two (or more) 555 timers in a single electronic circuit — useful enough that you can get two 555 timers in a single chip, called the 556 dual-timer chip. The 556

### Electronics Projects: How to Make a One-Shot Timer

In this project, you build an electronic circuit that uses a 555 timer chip in monostable mode. When a trigger switch is pressed, an LED lights and stays lit for approximately five seconds. Then, the LED

### Electronics Projects: How to Make an LED Flasher Using a Timer Chip

In this project, you build an electronic circuit that uses a 555 timer chip to alternately flash two LEDs on and off. Then, you modify the circuit so that the circuit is controlled by two pushbuttons that

### Electronics Projects: How to Make a Beeper

In this electronics project, you use two 555 timer chips to build an audible beeper, with both timers configured in astable mode. Each time controls a different audible tone on the beeper.

### Electronics Components: What are Operational Amplifiers?

An op amp is a super-sensitive electronic amplifier circuit that’s designed to amplify the difference of two input voltages. Thus, an op amp has two inputs and one output. The output voltage is often tens

### Electronics Components: How the Op Amp Came to Be

The modern operational amplifier dates way back to the early days of electronics history. Specifically, the op amp was first created in the 1930s, when Bell Telephone was just starting to run telephone

### Electronics Components: Open Loop Amplifiers

As its name suggests, one of the most basic electronic uses of an op amp is as an amplifier. If you connect an input source to one of the input terminals and ground the other input terminal, an amplified

### Electronics Components: The Ideal Op Amp

If you read about op amps on the web or in an electronics book, you’ll undoubtedly come across the term ideal op amp.An ideal op amp is a hypothetical op amp with certain characteristics that real op amps

### Electronics Components: Closed Loop Amplifiers

Open loop op-amp circuits aren’t very useful as electronic amplifiers because they’re so easily saturated. To make an op amp useful as an amplifier, you must use it in a

### Electronics Components: Feedback in Closed Loop Amplifiers

If you’re interested in understanding how the feedback circuit works, remember this rule of electronic op amps: If the input voltage is anything other than zero, the op amp will be saturated, and the output

### Electronics Components: How to Use an Op Amp as a Unity Gain Amplifier

A unity gain amplifier is an electronic amplifier circuit that doesn’t amplify. In other words, it has a gain of 1. The output voltage in a unity gain amplifier is the same as the input voltage.

### Electronics Components: Integrated Circuits in Schematic Diagrams

In an electronic schematic diagram, an integrated circuit is usually represented simply as a rectangle with circuit connections placed conveniently around the rectangle without regard for the physical

### Electronics Components: How to Power Integrated Circuits

In most DIP integrated circuits, two of the pins are used to provide electronic power to the circuit. One of these is designated for positive voltage, typically identified with the symbol V

### Electronics Components: Integrated Circuit Data Sheets

Before you work with the electronics of a specific type of integrated circuit (IC), you should download a copy of the data sheet for the IC. An IC datasheet contains loads of useful information. In addition

### Electronics Components: Popular Integrated Circuits

Thousands of different types of integrated circuits (ICs) are available for electronic devices. Most of these were designed for very specific applications. However, many integrated circuits have been designed
