  5. OCTOPUS Real-time Clock is a clock module which can achieve counting for year, month, day, hour by using the DS1307 clock chip.This chip has lots of merits, low power supply, with 56 bytes of non-volatile RAM clock calendar full BCD code real-time clock chip, the address and data via a two-wire bidirectional serial bus transmission, providing seconds, minutes, hours and other information , automatically adjusting the number of days in each month. And more surprisingly, the chip also equip with the function of leap year compensation. Chip has a built-in power-sense circuit, brownout detection, and battery switching function.

  6. Octopus 5mmLED light Brick, and special sensors Arduino board and ambient light sensor extension combination, can be used in the interaction with the light works. When the LED light module connected to Arduino, the digital pin (LOW on, HIGH off) is used to control it. The brightness of LED can be controlled via PWM output.

  10. Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and photoresistors. Photocells are basically a resistor that changes its resistive value (in ohms Ω) depending on how much light is shining onto the squiggly face. They are very low cost, easy to get in many sizes and specifications, but are very innacurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch. The variations can be really large, 50% or higher! For this reason, they shouldn't be used to try to determine precise light levels in lux or millicandela. Instead, you can expect to only be able to determine basic light changes.
