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"
Push buttons are core components of Arduino projects because it gives a user the ability to trigger a variety of actions and makes your electronics projects more interactive. In order […]Continue reading "Push Buttons & Switches"
Potentiometers are important components for unlocking more functionality from your projects. It’s a variable resistor whose resistance depends on the position of the knob. You can use them to adjust […]Continue reading "Potentiometers and the Serial Monitor"
We learned how to turn an LED on and off but what if you want a level brightness in between? We’ll be using the Arduino’s PWM pins and learn a new function for controlling the brightness of LEDs. Then we’ll explore RGB LEDs which allow you to mix different levels of red, green and blue to create a nearly endless array of colors.Continue reading "Controlling LED Brightness with PWM & Mixing Colors with RGB LEDs"
We kick off our journey into the world of electronics by getting to know the Arduino UNO board and how to get it up and running with the Arduino IDE software (which is free). With the Arduino properly connected to your computer or laptop, it’s time to get to know the parts of a sketch and even code your first few programs! By the end of the lesson, you’ll know how to turn on and off the onboard LED with code as well as make it blink, you’ll also build your first circuit with an LED diode and make it blink in a variety of patterns as you get comfortable using your first code functions.Continue reading "Intro to the Arduino to Blinking LEDs"
