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.
The TB6612FNG is a MOSFET-based dual H-Bridge motor controller that can be used in place of the popular L298N.
This controller is smaller and much more efficient. Best of all, you can use it in L298N designs without changing your code!
Let’s see how to make use of this H-Bridge with an Arduino
Today I’m going to compare the performance of a tiny Laser-based time-of-flight sensor, the TOF10120, with the classic HC-SR04 ultrasonic range finder.
After we hook the sensors up to an Arduino I’ll put them to the test on my “unique” testbed. The results might surprise you.
Learn how to use Bipolar Junction Transistors and MOSFETs to interface high-current DC loads with an Arduino.
We will cover both BJTs and MOSFETs in this guide to interfacing your Arduino with the outside world.
Today we will construct a simple bench power supply that has both fixed and variable output voltages. It’s a great project for beginners and useful enough for an expert!
Our design will make use of popular buck converter modules and an unused power “brick” from an old laptop computer, which you should have no problem obtaining.
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.
The NVIDIA Jetson Nano Developer Kit is a powerful AI development platform that can be had for only 99 US dollars.
Today we will look at the Nano and set one up with a microSD card image. We’ll also run a few test programs to show off its capabilities.
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.
