In order to really learn you must use your knowledge. In this section you will complete assignments that use what you have learned in section 1. 1. Change the blink. Change the speed of the blink or introduce a pattern of blinking. You can change the amount of...

Now lets take a look at the statements in the Blink code. The statements all end with “;” [code lang="arduino" firstline="8" gutter="0"] void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); } [/code] pinMode(13, OUTPUT); The first statement is pinMode. When the Arduino reads this statement it changes what job a pin...

[code lang="arduino" firstline="8" gutter="0"] void setup() { pinMode(13, OUTPUT); // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: void loop() { digitalWrite(13, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(13, LOW); // set the LED off delay(1000); // wait...

Most LEDs have a shorter lead and a flattened edge which indicate the cathodeWhen we connected our Arduino with the computer we tested the connection by blinking an LED on the Arduino. In this section we will build an external LED circuit for the Arduino...

First, lets connect our breadboard to Power and Ground on the Arduino board. The breadboard has two long strips for Power and Ground on each side. I put my Arduino right on top of the breadboard and hold it there with a rubber band or...

First lets quickly go over the basics. It all starts with electricity. Electricity is the flow of electrons through a conductor like metal. We can use electrical components to make a circuit that does things like lights up. One such component is the transistor. The...

When we move from the analog world of the Discover Electronics Kit to the digital world of the Arduino, we will want to understand a bit about how these different worlds work and how they meet.There are several parts to working with the Arduino and...

The Atari Punk Console is a popular circuit that uses two 555 timer chips or a single 556 dual timer IC. The original circuit, called a "Sound Synthesizer", was published in a Radio Shack booklet: "Engineer's Notebook: Integrated Circuit Applications" in 1980[1] and later called...

An electrical circuit allows electrons to flow from one side of the circuit to the other. The two ends of the circuit have a difference in electrical charge. One side is more positively charged than the other. Electrons are attracted to the positive side and...

Atoms and Matter All matter is made of atoms. Atoms are made up of tiny particles we call electrons, protons and neutrons. Protons and, usually, neutrons form the center (nucleus) of the atom. Electrons spin around the nucleus. All matter is made up of these few parts....
