This example shows how to send data from a personal computer to an Arduino board to control the brightness of an LED. The data is sent in individual bytes, each of which ranges in value from 0 to 255. Arduino reads these bytes and uses them to set the brightness of the LED. You can […]
I recently had the idea to create a catapult, But not just any kind of catapult, an electronic catapult! I wanted something I could just sit it down hit some buttons and watch it do its thing without being to big. This is what I came up with: It is a little bigger than what […]
Have you ever wondered how migratory birds manage to have such an amazing sense of direction despite being so generally clueless? They can sense the Earth’s magnetic field with what is basically a compass built into their body. Wouldn’t it be cool to feel what that’s like? The following instructions are loosely based off of […]
I had initially planned to do an LCD tutorial a little further down the line, but there was very high demand for it, and I already had a circuit assembled for testing the new LCD that element14 sent me to evaluate. So, this seemed like an appropriate time to roll it out! In this episode, […]
In this instructable, I will show you how to make a sensor that will light up more lights the closer you are to it. Step 1: Placing The Electronics This step will show you where and how to place the electronics on the breadboard Materials: 6-220 ohm resistors 3 green LED’s 2 yellow LED’s 1 […]
You can add Strings together in a variety of ways. This is called concatenation and it results in the original String being longer by the length of the String or character array with which you concatenate it. The + operator allows you to combine a String with another String, with a constant character array, an […]
I have a problem, I’m trying to lose weight but I love snacking late at night. And no one knows that I even do it. That being one of my biggest hurdles, I figured why not include all my social media friends and followers in helping me. Whether they know it or not. So I […]
Wearable Arduino mod for your headphones. Non-invasive procedure for headphones that don’t have room inside the drivers or you don’t want to hack apart your high end cans. Adafruit just put out a tutorial for adding pattern blinking LED lights to headphones. This instructable takes it one step further. This project is really the Adafruit Ampli-tie project morphed […]
When you flip a switch, the coffin lid opens and a smiling red eyed ghost arises. The ghost flings some candy, pushes the switch back and returns to rest. Then, the coffin lid closes. Step 1: Major parts include: 4.5 rpm motor #155821 Jameco.com 1.8 rpm motor #176050 Jameco.com Two shaft couplers #162270 Jameco.com Servo […]
A fountain can make a nice decorative fixture for your garden. But it isn’t always easy to run a power cord out to where you want it. So I decided to run it on solar power. The system is controlled by an Arduino. This allows you to save energy by programming when the fountain will […]
