This example shows you how to monitor the state of a switch by establishing serial communication between your Arduino and your computer over USB. Hardware Required Arduino Board A momentary switch, button, or toggle switch 10k ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to

Hi guys, I bring a new instructable for arduino, the control access with password, 4×4 keypad and a servo. We will use the Password and Keypad librarie for arduino, besides using the servo library, but this project can also be modified by changing the servo, a motor reley or motor stepper, or any other ideas

Hi, First of all, my English is not perfect =) I’ve seen many projects with Arduino that describes how to control 2 servo’s with a joystick or use a lcd screen. All of the projects that i have seen are all seperate things. So i decided to make a short Instructable of these things combined.

Hello Everyone. This is my very first Instructable so please go easy on me. This was more or less a test project to see if my new arduino board worked. Any friendly advice will be greatly appreciated so my future posts can be even better. I am going to show you how to create the

Arduino HC-SR04 The Arduino HC-SR04 is different from most of those commonly seen on the market, which have 4 pins compared to 3 pins. But the operation principle is the same, transmit signal, and depends on when the signal is received to estimate the distance. Arduino HC-SR04 not only inexpensive but also practical, use a

For my project, the Arduino output is not enough so digging on the net and asking to a friend some help, I managed to build an amplifier to feed my 3 computer fans. This circuit can be used as an amplifier to switch on and off a DC motor and to regulate its spinning speed

This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs. The schematic shows that wiring the

Arduino is not restricted to receiving data from sensors only; you have the ability to also link a full-size PS/2 keyboard and type as you would on a traditional computer. Attaching a keyboard to an Arduino may seem strange (since it’s a small microcontroller), however, it should be noted that an Arduino has greater processing
