Using remote controls with your Arduino projects is a great way to control robots, lights, relays and more – wirelessly. We’re going to learn how infrared remotes send information to […]Continue reading "IR Remotes & Receivers"
The pins from the Arduino can power a variety of components up to 5V but anything requiring more voltage or current can damage the Arduino if you try to hook […]Continue reading "Relays & Transistors"
Now that you know how to connect a variety of components to your Arduino, you’ll be inspired to build larger and more complex projects. But what happens if you don’t […]Continue reading "Expand your Pins with Shift Registers"
Ultrasonic sensors can measure distance and are great for obstacle avoidance and robotics projects. Like a bat, it uses a method similar to echolocation to determine how far it is […]Continue reading "Ultrasonic Sensors"
The popular DHT11 humidity and temperature sensor gives you two functionalities in one! It’s relatively simple to use but we’ll have to download and install an external library. These sensors […]Continue reading "Humidity & Temperature Sensors"
Displays like LCDs or the 7-segment variety allow you to untether your projects from the computer by giving you another more portable way to display information rather than the serial […]Continue reading "Displays"
The first thing that comes to mind when you think of joysticks is gaming. Although these components can be used to create a variety of games with your Arduino, they’re […]Continue reading "Joysticks"
It’s time to put some motion into our projects! Servos are great for acting as levers, pulls, robot arms, gauge indicators and anything that needs 180 degrees of rotational movement. […]Continue reading "Servos"
Photoresistors are light-dependent resistors whose resistance changes depending on the amount of light hitting the sensor. This makes them perfect for light-controlled switches and projects. When paired with a relay […]Continue reading "Photoresistors & Thermistors"
