You want to send data to a serial device such as a serial LCD, but you are already using the built-in serial port to communicate with your...

You want to receive data on Arduino from a computer or another serial device; for example, to have Arduino react to commands or data sent ...

This led matrix can be programmed using arduino, various patterns can be made using functions and by specifying the LED's on the array...

DC motors, which you can find in numerous devices around your home, rotate continuously when a DC voltage is applied across them. Such mot...

All digital inputs use a pullup or pulldown resistor to set the “default state” of the input pin. Imagine the circuit in Figure below witho...

we can generate analog output values by using a trick called pulse-width modulation(PWM). Select pins on each Arduino can use the analogWri...

When was the last time you had to hold a button down to keep a light on? Probably never. It makes more sense to be able to click the butto...

We are first going to simply control the speed of a DC motor, in one direction, using a power transistor, diode, and external power supply ...

In this project we will alter the brightness of the LED, and make a pulsating lamp, using the analogWrite() function. Parts Required Ta...

We are now going to use a string of LEDs (10 in total) to make an LED chase effect (see Table 3-1), similar to that used on the car KITT i...

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for art...
