We have seen how to control DC devices with an Arduino, now it’s time to learn how to control AC equipment.
In this article I will show you a SAFE method of experimenting with AC on your workbench.
We will also build a light-activated relay and a marquis-style light chaser using solid state switches.
Basic Logic chips have been around for a very long time, yet they are still used in new designs. An understanding of how basic logic chips work will move your design skills up a notch.
Today we will look at the most elementary of logic chips, the basic gates. We’ll also learn about logic families, and we’ll see how to create a logic chip emulator using an Arduino.
We’ll finish up by designing a simple intruder alarm using an Arduino and a basic logic gate.
In this rather shifty article I’ll show you how to use some fundamental electronic building blocks – shift registers.
These handy devices can let you add oodles of input and output ports to your Arduino or other microcontrollers, and they’re very easy to use..
Follow along and learn how to make 74HC165 and 74HC595 shift registers work for you.
Today we will look at not one but five different temperature sensors that you can use with the ASrduino
With different temperature ranges, accuracy and interface methods you’re sure to find one that is perfect for your next project!
Learn about the Peltier Effect and how to use a common and inexpensive Peltier cooler to cool down your electronic projects. We will perform a few experiments with a Peltier module, including using it to make ice!
We will also hook up a Peltier Cooler assembly that you can get on eBay.
An Analog Feedback Servo Motor is a servo motor that has a connection to its internal feedback potentiometer. Thi sallows you to measure the precise position of the motor shaft in real-time
Today we will learn how to calibrate and use this motor, we’ll even see how it can be used as an input device to memorize and repeat a sequence of movements.
What do you do when you want to save data in your Arduino project and have it available even after the Arduino is powered down? One excellent way of doing this is by using EEPROM – Electrically Erasable Read-Only Memory.
In this article you will learn how to use both internal and external EEPROM with an Arduino.
Today we will learn how Hall Effect sensors and switches work. These handy devices are activated using magnets.
After that we will use a couple of Hall Effect switches to control the position of a stepper motor. Using an Arduino, we’ll build both Limit Switches and a Homing Sensor.
Prototyping and breadboarding is an essential skill for anyone working with electronics or experimenting with microcontrollers and microcomputers.
In this article I will show you the basics of breadboarding, along with some breadboard accessories that you are sure to find useful.
The RCWL-0156 is an inexpensive yet useful proximity sensor that can be used on its own or with a microcontroller like an Arduino Uno.
The device is unique in that it uses microwaves and Doppler Radar to detect moving objects
In this article I will show you how the device works on its own and how we can add an Arduino (or two) to create some useful projects
