This is battery level display module based on battery style digital tube LED. The 5 - segment LED inside is red light and the frame is green light. There is driver chip TM1651 onboard, so the control interface is simple, just two signal lines and VCC / GND. It can be used to display the battery power.

It's a small breakout board for the ENC28J60 Ethernet chip. Contains all the necessary hardware to implement an Ethernet interface including the isolation transformer and LINK/STATUS and power LEDs. SPI interface makes this one of the easiest 10Base-T ICs yet. It's 3.3V with 8KB buffer.
This is a standard solderless breadboard - three binding posts, 4 power buses, black aluminum plate backing. It works with a wide variety of wire gauges (29-20 AWG). With a total of 1660 tie in points, all pins are spaced by a standard 0.1".
Bread board or toy? Both! Bread board can also be very interesting, just like play with blocks. You can inserted these boards anywhere on its base board to build your circuit, not subject to limitation of traditional bread board. In addition, 6 distinctly different colors makes the circuit more clear.
Sensor is to create Digital (Lo Pulse) output to Particulate Matters (PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust in clean room.
