learn PARTS ON YOU KIT need for arduino(part-2)

Diode  :- Ensures electricity only flows in one di-rection. Useful when you have a motor or other high current/voltage load in your circuit. Diodes are polarized, meaning that the direction that they’re placed in a circuit maters. Placed one way, they allow current to pass through.Placed the other way, they block it. The anode side generally connects to the point of higher energy in your circuit. The cathode typically connects to the point of lower energy, or to ground. The cathode is usually marked with a band on one side of the component’s body.Gels (red, green, blue) - These filter out difer-  ent wavelengths of light. When used in con-junction with photoresistors, they cause the sensor to only react to the amount of light in the filtered color.  H-bridge :- A circuit that allows you to control the polarity of the voltage applied to a load, usually a motor. The H-bridge in the kit is an intigrated circuit, but it could also be constructed with a number of discrete components.   Jum...

learn PARTS IN YOUR KITS need for arduino(part-4)

Pushbutons :- Momentary switches that close a circuit when pressed. They snap into bread-boards easily. These are good for detecting on/off signals. Resistors :- Resist the flow of electrical energy in a circuit, changing the voltage and current as a result. Resistor values are measured in ohms (represented by the Greek omega character: Ω). The colored stripes on the sides of resistors indicate their value (see resistor color code table). Servo motor :- A type of geared motor that can only rotate 180 degrees. It is controlled by sending electrical pulses from your Arduino.These pulses tell the motor what position it should move to. Temperature sensor :- Changes its voltage output depending on the temperature of the component. The outside legs connect to power and ground. The voltage on the center pin changes as it gets warmer or cooler. Tilt sensor :- A type of switch that will open or close depending on its orientation. Typically they are hollow cylinders with a metal ball inside...
