#Lesson 01- Blinking LED                 The simplest thing you can do with a Arduino to blinks the LED Hardware Required   -   Arduino Board   -  LED   -  220 Ω Resistor   -  Jumper wire   -  Bread board Circuit       The LED is connected to Arduino digital pins and 220Ω resistor is connected series in between Arduino and LED. The resistor which limits the flow of currents.      Connect one end of the resistor to the digital pin correspondent to the LED. Connect the long leg of the LED (+ve leg called as anode) to the other end of the resistor and connect the short leg of the LED (-ve leg called as cathode) to the Gnd Code After you build the circuit plug the Arduino into your computer, start the Arduino software(IDE) and enter the code given below /*   Blink   https://electronicassit.blogspot.in/   9444868542 *...
