Arduino Tutorial – DC Motor Control with L293D Motor Driver

This is a very useful chip. It can actually control one motor independently. We will use in its entirety the chip in this tutorial. Pins on the right hand side of the chip are for controlling a one motor. Pins on the left hand side of the chip are for controlling second motor.   You can run four solenoids, two DC motors or one bi-polar or uni-polar stepper with up to 600mA per channel using the L293D.  

Arduino Tutorial – Install and Use Arduino Libraries (No Such File or Directory)

Arduino libraries are a convenient way to share code such as device drivers or commonly used utility functions. This guide details how to install libraries on your computer.   There are two general types of Arduino Libraries: Standard Libraries User Installed Libraries   Where to Install your Libraries? Your sketchbook folder is the folder where the Arduino IDE stores your sketches. This folder is automatically created by the IDE when you install it.   Using Libraries One of the best features of the Arduino project is the ability to add on pre-crafted libraries that add hardware support. There’s tons of…

Arduino Tutorial – digitalRead Serial Monitor with Button

Arduino Basic Tutorial digitalRead Serial Monitor with Button. Reads a digital input on pin 2, prints the result to the serial monitor.   When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and reads as LOW, or 0. When the button is closed (pressed), it makes a connection between its two legs, connecting the pin to 5 volts, so that the pin reads as HIGH, or 1.
