Using OLED Displays with Arduino

Using OLED Displays with Arduino
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.

Experiments with the RCWL-0516 – Doppler Radar Distance Sensor

RCWL-0516 Microwave Proximity Sensor

The RCWL-0156 is an inexpensive yet useful proximity sensor that can be used on its own or with a microcontroller like an Arduino Uno.

The device is unique in that it uses microwaves and Doppler Radar to detect moving objects

In this article I will show you how the device works on its own and how we can add an Arduino (or two) to create some useful projects

Pixy2 Camera – Object Recognition with Arduino & Raspberry Pi

Pixy2 Camera

The Pixy2 is an amazing camera that is capable of object detection, line tracking and barcode reading. All this in a tiny and very affordable little package

In this article I’ll take a look at the Pixy2. I’ll show you how to hook it up to an Arduino and how to train it to recognize objects. You wil see how easy it is to work with this camera to add vision sensing to your next project

Arduino UV Index Meter – Measuring UV Light

Arduino UV Index Meter

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.

So grab your hat and sunscreen and follow along!

DFRobot 5 DOF Robot Arm – Building the Robotic Arm

Robot arm with controller

The DF Robot 5 DOF Robot Arm kit is a high-quality robotic arm that you can assemble yourself. With heavy duty servo motors and sturdy aluminum parts this inexpensive arm is perfect for your robotics experiments

Follow along as I assemble the robot arm. I’ll also build a simple robot arm controller based on the Arduino Nano and the PCA9685 16-channel PWM module.
