Introduction The Arduino is an amazing device. It’s useful for prototyping and can also be used to construct a complete project. It has an analog to digital converters (ADC), digital I/O pins, it handles interrupts and it can communicate via
OLED displays are bright, lightweight and visible under a wide range of lighting conditions. They are available with both I2C and SPI interfaces and in this article, I’ll show you how to hook up and use both types with an Arduino.
In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.
Ultraviolet Light is used in many industrial and medical applications. We also receive a dose of UV light from sunshine, and while a little UV light is good for you excessive exposure can lead to eye and skin damage.
In this article I will explain how to safely work with ultraviolet light and I’ll show you how to build a UV Index Meter that can accurately measure the level of UV and help keep you safe in the sunshine.
Introduction One advancing technology that has been impossible to ignore lately has been the work with self driving vehicles. These vehicles have gone from scientific curiosity to mainstream within a few short years and soon we’ll be seeing them as
Servo Motors are a staple for hobbyists in a variety of fields. Whether you’re building model planes and boats or working with robotics you are sure to come up with dozens of applications just perfect for a servo motor.
Come and explore the use of inexpensive analog servo motors. They are inexpensive and easy to use. When coupled with an Arduino you can build all sorts of projects that move.
And if you need LOTS of servo motors we have just the thing for you – the PCA9685 16 Channel PWM controller. Using this board you can control 16 servos with just two connections to your Arduino. And you can expand that to 992 servos if you really need a lot of motors!
