In this first of a two-part series we will learn how to measure both DC voltage and DC current using an Arduino Uno. Although the examples all use the Uno, what we learn here can be applied to any microcontroller.
The second part of the series will, of course, focus on Alternating Current.
Today we will look at PlatformIO, an alternate IDE for working with the Arduino and many other microcontrollers.
You’ll learn how to install PlatformIO under Visual Studio Code, and also how to use it to program for the Arduino Uno, The ESP32 and Seeeduino XIAO.
Once you get used to it you’ll see that PlatformIO has many advantages over the Arduino IDE.
Come and meet the XIAO, a tiny 32-bit Arduino-compatible microcontroller that goes for only 5 dollars!
This amazing little device outperforms the Arduino AVR boards and offers features like an analog output and 10 PWM pins.
We will explore the XIAO using the Arduino IDE and see how easy it is to use.
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.
Matrix Keypads are a great way to add a professional-looking user interface to your Arduino project. They are inexpensive, and very easy to use.
In this article I’ll show you how to use a matrix keypad with an Arduino. We will also use our keypad to build a simple electronic combination lock with an LCD display.
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.
I2C address conflicts are a common problem, and in this article, I’ll show you how to resolve them by creating multiple I2C buses with your Arduino.,/p>
I’ll demonstrate how the TCA9548A I2C Multiplexer works by using two identical OLED displays and sending them unique data even though they share the same I2C address.,/p>
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!
Put some color into your life and learn to use two different color sensors with an Arduino!
In this article and video I’ll show you how to calibrate and use the TCS230 and ISL29125 color sensors.
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
