DFR0555 Gravity: I2C LCD1602 Arduino LCD Display Module (Blue)
US$19.75
Referring to the LCD16020, I believe that everyone is not unfamiliar with the square shape, green color, a row of 2.54 pin header.... LCD1602 module is a product of the DFRobot Gravity IIC series, which has been greatly optimized for its original LCD1602 appearance. This module does not need to adjust the contrast, retain the backlight controllable function, and simultaneously compatible with 3.3V and 5V voltage. The optimization of function and the appearance will bring you the different experience.

LED-RING-7 Addressable RGB LED ring – 7x WS2812 LEDS
US$5.59
This is a chainable board equipped with 5050 WS2812 RGB LEDs. The WS2812s are each addressable as the driver chip is located inside the LED. Each pixel has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and requires 5V. Every ring is equipped with a single data line with a very timing-specific protocol requiring a real-time microcontroller with a 8MHz or faster processor such as an AVR, Arduino, PIC, mbed, etc. This ring has 7 pixels with an 22mm outer diameter. There is four fixation holes on the ring to screw it into place, and four solder pads for connections.

LED-RING-KIT RGB LED Ring 8/12/16/24 Bit WS2812 5050 RGB LED with Integrated Driver
US$34.93
Round and round and round they go! The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has 18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock!

LED-102, 0.36” Red 4-Digit 7-Segment LED Display (Common Cathode)
US$2.79
These 0.36” 4-digit 7-segment LED displays are big enough to see from a distance but not so big that you’d have trouble finding an enclosure for them. These common-cathode displays feature 4x 7-segment digits and one decimal point per digit. The LEDs have a forward current of 30mA. Connect Ground to pin 12,9,8 and 6. Insert 2.5VDC into pins 1 – 5, 7,10,11. See schematic to view pinouts. Pin 1 starts from the left with the first digit.

LDR-05 Photo-Resistor 5mm diameter LDR (Light Dependent Resistor) N.C. (Normally Closed)
US$0.55
This is a normally closed switch, when light is present it will allow the input voltage and current to flow through. When light is absent, the unit acts like a resistor slowly increasing up to 20MOhms and upwards to act as a normally open switch. This unit comes in the body of a 5mm led, don’t be fooled as it might look like an LED at first glance. Unit sold individually.
