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] […]

Just as you can concatenate Strings with other data objects using the StringAdditionOperator, you can also use the += operator and the cconcat() method to append things to Strings. The += operator and the concat() method work the same way, it’s just a matter of which style you prefer. The two examples below illustrate both,

This collection of short Arduino sketches introduces a variety of programming concepts. The comments are minimal as these are intended to be starting points for explanation. blink // 1. blink the onboard Arduino LED on pin 13. // 2. demonstrate setup(), loop() // 3. demonstrate pinMode(), digitalWrite(), delay() void setup() { pinMode(13, OUTPUT); } void

In Amateur radio, Morse code is used to send messages using a series of short or long pulses which are heard by the operator as audio beeps. The short beeps are known as dots or dits, and the longer beeps are known as dashes or dahs. To be understood, the duration of the dits and

This sketch blinks the Esplora’s RGB LED. It goes through all three primary colors (red, green, blue), then it combines them for secondary colors(yellow, cyan, magenta), then it turns on all the colors to create white. For best results, cover the LED with a piece of white paper to see the colors blend. Circuit Only

Arduino is an open source hardware and software company that creates Single Board Controllers (SBC) and Microcontroller kits, and these kits come in a Do-It-Yourself (DIY) form. Arduino can be used by almost anyone because it is inexpensive and also easy for professionals and even amateurs to use. Despite the fact that Arduino kits come

[Michael Pick] calls himself the casual engineer, though we don’t know whether he is referring to his work clothes or his laid back attitude. However, he does like to show quick and easy projects. His latest? A little portable Tetris game for $9 worth of parts. There is an Arduino Pro Mini and a tiny display along

The HC-SR04 Ultrasonic range sensing module is great for sensing distances that can be used as an input for your Arduino projects, but using multiple (more than two) can quickly cost you a lot of pins. This basic Instructable gives you the code and basic instructions to use the 74HC595 8 bit series to parallel
