TB6612FNG H-Bridge with Arduino – Better Than L298N?
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
Control Large DC Gearmotors with PWM & Arduino
Pulse Width Modulation, or PWM, is an excellent method of controlling DC motors, however controlling large gearmotors can be expensive and difficult – but it doesn’t have to be.
Today I will introduce you to an inexpensive yet powerful H-Bridge motor driver, the Cytron MD10C.
In addition, we will see how altering the PWM frequency can improve performance tremendously.
ESP32 Guide 2024 – Choosing and Using an ESP32
Since its introduction in 2016, the ESP32 has become one of the most popular microcontrollers in the world. It has now grown from a single ESP8266 replacement chip into a complete line of powerful microcontrollers and communications modules.
Today we will look at the status of the ESP32 as of January 2024. We will also take a look at a new Alpha of the ESP Boards Manager for the Arduino IDE.
Tools for Electronics – Selecting Tools for Your Workshop

This guide is for experimenters, creators and service folks of all levels. Check it out and pick up a few new tools for your own workshop!
ESP32-CAM Object Detection with Edge Impulse
Object Detection used to require huge computing resources, but that has all changed. Using the power of Edge Impulse, you can train an object detection model that will run on an inexpensive ESP32-CAM board.
This article will show you all the steps you need to take, from taking images of your objects to training them with a neural network. And it’s really easy too!
Arduino GIGA R1 WiFi
The new Arduino GIGA is the most powerful microcontroller that Arduino has ever produced.
Today we will take a first look at this monster, which has the same form factor as the Arduino Mega.
Of course, we’ll test out some of the more unique features of this board as well.
Measure Air Quality with Microcontrollers
Measure the quality of the air you are breathing using a variety of sensors, an Arduino and an ESP32.
In this article I’ll discuss air quality parameters and show you how to use several popular sensors to measure the gases and particulate matter in the air
Raspberry Pi – 10 Years & 10 Projects
Celebrate 10 years of the Raspberry Pi by building 10 unique Pi projects. Every model, from the Zero to the Raspberry Pi 4 and the Raspberry Pi Pico are included.
We’ll also cover the history of this amazing little microcomputer.
So come and join the party!
Safely using LiPo Batteries
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.
