1602 LCD Display Module

This is great LCD display compatible with arduino.

With limited pin resources, your project will quickly run out of resources using normal LCDs. With this I2C interface LCD module, you only need 2 lines (I2C)to display the information.

If you already have I2C devices in your project, this LCD module actually cost no more resources at all. The address can be set 0x2.

74HC595 and Segment Display

Common anode 7-segment display Each segment of the display consists of an LED. So when you use it, you also need use a current-limiting resistor.

Otherwise,LED will be burnt out. In this experiment,we use a common cathode display. As we mentioned above, for common cathode display, connect the common cathode (COM) to GND. When the anode level of a certain segment is high, the segment is on; when the anode level of a certain segment is low, the segment is off.

LED and 830-hole Breadboard

LEDs are included in many lighting industries, the industrial community is depending more and more on LEDs.

In this lesson, a simple yet interesting experiment will be conducted, using LEDs to create flowing LED lights. As the name implies, these flowing lights are made up of six LEDs in a row which successively light up and dim one after another like flowing water.
