Linear DC Power supplies are no longer as common as switching supplies, but they are still a good choice for many applications.
Today we will learn how linear power supplies work, how they differ from switching power supplies, and how to use voltage regulator modules.
We will then construct a DC Power Supply suitable for use on the workbench.
The 555 is one of the most popular integrated circuits ever created, with over a billion of them produced every year. In many cases, the 555 is a simpler and better choice than using a microcontroller.
Today we will learn how the 555 works, and then we will build five simple projects using a 555 timer.
LiPo batteries are incredible powerhouses, they have a higher power-to-weight ratio than any other type of battery.
But with all that power comes a number of safety concerns, and not following them could lead to a deadly LiPo fire.
Today we will learn how LiPo batteries work, how to charge, discharge, balance, store and dispose of them. And, just in case, we’ll see how to extinguish a LiPo fire.
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.
