DIY Arduino Unit Converter: How to use LCD

Step 1: Ingredients: Electronics Arduino Breadboard LCD* 2x 50k pots 150 ohm resistor Jumper wires, and tons of them! If you do not want to use a LCD then you will have to use serial monitor. Wherever you see lcd.print just change it to Serial.print. Instead of lcd.begin change it to Serial.begin(9600);. Step 2: The LCD So the first thing I did was go to the Arduino website and see how to hook up my LCD scr ...

Arduino String Comparison Operators Code

The String comparison operators, ==, !=,>, < ,>=, <= , and the functionsequals() and equalsIgoreCase() allow you to make alphabetic comparisons between Strings. They're useful for sorting and alphabetizing, among other things. The operator == and the function equals() perform identically. It's just a matter of which you prefer. So if (stringOne.equals(stringTwo)) { [Get Code] is identical to if ...

Switch Statement used with serial input using Arduino

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use switch to turn on one of several different LEDs based on a byte of data received serially. The sketch listens for serial ...

Make your own custom Arduino compatible

I love Ardunio. I love the things that people make with them and I love to make my own. Last August I published an Instructable on how to make your own postage stamp sized Arduino compatible. This Instructable will show you how to to make a rugged, versatile Ardunio compatible with basic components on board. It will be more suitable for deployment in the real world than a bread board attached to a developme ...

DIY Skee Ball Machine

The skee ball machine is a wonderful thing. The simple experience of rolling a ball into a target is so freakishly satisfying that I used to play as much as I could as a kid at the local amusement park/mini-golf course. The sound of the rolling ball on the ramp, the pop as it launched in the air, and the bouncing as you hoped it would hit the 50 or even the 100. So when the idea for doing a bigger project c ...

Homemade arduino printer

If you want to make your own high resolution printer (maybe not so high res), you are at the right place. This Instructable will show you how to do with two dead cd/dvd drive and a pen (pilot, whiteboard marker, whatever you have) at the best lego-printer style. Here is how our printer will work: we type any message in terminal then the message will be printed (as dot matrix) and after the message is printe ...

Arduino MIDI Foot Pedal Keyboard

The Origin My dad is a musician.  He can play a multitude of instruments.  However, he only has two arms, BUT he also has legs!  That's when we decided that we would reuse the foot pedals from an old organ and convert them into an arduino powered MIDI keyboard.  Now he can easily play electric guitar and fill the empty sound with excellent bass notes produced from his QS8 Quadrasynth. An Introduction to MID ...

DIY Arduino Motor Shield

Today, I'm going to show you how to make an Arduino motor shield (driver) at a low cost. It works splendidly, its posses almost all the characteristics of the original Arduino motor shield. It's almost considered as a clone. The original Arduino motor shield has the same motor driver chip (L298), the only difference with it, is the package type, my project contains the vertical version of the chip L298 (wit ...

Arduino Board Step Sequencer

I was wondering about on making a sequencer, a big 16 step sequencer was what I wanted to make. To it's full extension with lots of features including single leds for each step, midi input and output, etc. Then I realised that I should start from a more basic model and then maybe tweak around to see what I can do. So while surfing the web and between other small sequencer projects I found this arduino seque ...
