  • {"27":"A relay is a switch. The switch is flipped by an electromagnet that is controlled by the Arduino. The switch is electrically isolated from Arduino and can control large amounts of power to lights, motors, pumps, etc. The photo above shows 2 relays, (the blue boxes) mounted on a printed circuit board that makes connecting easy.\n","33":"A breadboard is a reusable construction base for creating new electronics projects. Wires and electronic components with pins, such as Resistors, LEDs, Buzzers, etc. can be plugged into the holes in the Breadboard to create needed circuits. The internal connections are shown on the following slide.\n","22":"These are some of the connection devices used with Arduino, breadboards, etc. The ribbon cable has many wires that are lightly stuck together and can be easily striped off as individual wires or groups of wires to connect to various devices. The wires ends have female sockets that can plus onto the 3-Pin connectors on the Yourduino or other devices that have male pins. When a wire needs to have a pin end such as those shown on the far left, a double ended pin like those shown on the pin strip on the right, is snipped off and plugged into the wire end. These male ends also plug into the breadboard holes.\n","28":"Servos are small box-shaped electro-mechanical devices that contain a DC motor, electronics to control the motor from a signal, a gear system to produce slow/strong output to a shaft, and a position feedback potentiometer. There are a variety of sizes and weights, of similar construction. They are widely used in Model cars and airplanes, and can cost as little as $3.50\n","34":"Here is an Arduino connected to a Breadboard which we will later use to plug in and connect many different devices. Breadboard details later. The Red wire connects connects Arduino 5V to the Red 5V rail running across the top of the Breadboard. The blue wire connects Arduino Ground to the blue Ground rail. Next let’s look in detail at the Arduino connections and the details of the Breadboard.\n","35":"This shows a Push button switch and Pulldown resistor connected between the +5V rail and the Ground rail. The connection point between the switch and resistor is connected to an Arduino Input pin. \n","24":"These 2 devices make sound from electrical signals. They are different in that the Buzzer makes a continuous sound when a voltage (usually 5V) is applied. The Beeper is a simpler device which moves its speaker in response to an applied voltage. Applying a voltage once will make a single click. However, Arduino can send a series of pulses to a Beeper and make many different sounds.\n","19":"Here’s a more detailed look at YourDuino Robo1. It can be used to make many different types of intelligent devices such as: robots, home control systems, artistic displays, etc. It is easier to use than the original Arduino because it has added connectors for plugging in a wide variety of input and output devices. Next we will look at ways of connecting external devices to Arduino.\n","36":"This shows the Output circuit which you saw on the Right side of the diagram. Here an LED and resistor are connected in series to the Ground rail and the LED is connected to an Arduino Output pin. Software such as the “Blink” sketch can switch the Output pin back and forth from LOW to HIGH, (Ground to +5V) and blink the LED. Now let’s look at some LEDs and how they are connected.\n","25":"A Potentiometer is a mechanical device whose resistance changes with the physical rotation of an input shaft. (Which often has a knob attached to it for people to turn, such as the volume control on your stereo) A Potentiometer is a resistor which is made in a circular shape. \n","20":"Here’s a closer look at the upper section of 3-Pin digital I/O connectors. Arduino digital I/O pins can be used to connect to various different Digital Input devices such as: Push Buttons, Tilt Switches, Light Sensors, Motion Detectors, etc. The same pins may also be used to connect to various different Output Devices such as: LEDs, Buzzers, Lasers, Relays, etc. Each signal pin is in a 3-Pin group which includes Ground and +5V which may be connected easily to devices that need those connections.\n","37":"This schematic diagram shows the way we think about the electrical reality of Arduino and the connections to external devices. At the top, we have a red line representing the +5V power for Arduino and other devices. At the bottom, we have a blue line representing the ground connections to Arduino and devices. All external devices must be connected in some way between the 5V rail and the ground rail. In this example, on the Left, an Arduino Input pin is connected to a pulldown resistor to ground (Low) and a push button switch to 5V (High). The pulldown resistor brings the Input to Ground (Low) until the switch is pushed which connects the Input to 5V (High). Software in the Arduino can notice that the Input signal has changed from Low to High and it can make a decision to take some action. In this example the software can switch the Output connection from Ground to High, which will turn on the LED. Next we will look at how to physically connect devices to Arduino.\n","26":"This is an electronic thermometer which has high accuracy over a wide range (accurate to ±0.5°C over the range of -10°C to +85°C). You can locate these thermometer chips up to 100M away from your Arduino. Shorter cables can be just 2 wires. Digital signals are sent to and from the chip by Arduino to control it and read the temperature.\n","21":"This lower section of 3-Pin connections is for Arduino Analog I/O Pins which can measure voltages in the range of Ground to +5 Volts. These may be devices which return a value such as: Light level, Temperature, Pressure, Soil Moisture, etc. instead of simply HIGH or LOW. These pins may also be used as regular Digital I/O pins.\n"}
