Mini Water Pump (DC3- 6V, Waterproof, with Water Pipe)

Description

This is a low cost and easy to use mini water pump. It is very suitable for mini auto watering project for plant or fishing, also very good for building a mini submarine.

It can work under DC 3 to 6V. The size is very small, and waterproof, just put it in the water and it will pump (of course it needs power). 

By default we will add 1 meter water pipe with one water pump. You can choose longer pipe.

We have two type of pumps, one is horizon, one is vertical. Check the dimension here:

Relay Module (5V, 1 Channel)

Description

This is a very normal and simple relay switch. MCU could not directly control home device, because MCU only operates at low power - 5V, but home device operates at high voltage - 110V- 220V. Relay is the best solution to control the high voltage device with MCU. Here for this module, there is one side to connect with MCU, and other side to connect high voltage device with the terminals. Just need to use MCU's Digital pin to send a high level to module, the high voltage terminals will turn on, otherwise it will turn off.

Specifications

• Turn on at high level, turn off at low level.
• Operation Voltage: 5V
• Max. power can be connected: 10A @250VAC, 15A @125VAC
• Dimension: 17.2x43.1x16.4(h)mm

10PC RGB LED PACKET (5050)

Description
WS2812B is a 5050 RBG LED with integrated driver chip. By the integrated driver chip, it can achieve 1024 points of cascading (refresh rate at 30fps), and every pixel is individually addressable. Every pixel of 256 brightness display and 16777216 color variance. Only the 4th pin of the WS2812B, the integrated driver circuit and LEDs share the same 5V power, and 2 pins for signal transmission. Because of the ingenious design, the circuit design for this LED become very simple.

REAL TIME CLOCK MODULE (I2C)

Features:

• Consumes less than 500nA in battery-backup mode with oscillator running
  
• Automatic power-fail detection
  
• 56-Byte, battery-backed, general-purpose RAM
  
• Backup by AT24C32 32Kbit
  
• I2C Serial Interface

Description:

This little, RTC (real time clock), will keep track of time even if reprogrammed or if power is lost. Use it in projects for data logging, clock-building, time stamping, timers, alarms, etc.

Since an Arduino microcontroller’s time keeping ability (millis()), is very limited in capability—i.e. can only keep track of time since its last power-up—it’s useful to have a separate RTC chip to keep a consistent count.

This module will keep track of time by seconds, minutes, hours, days, months, and year. You can program it to run either by 24-hour or 12-hour formats with AM/PM. It even accounts for months with less than 31 days and leap-years.

While the battery is not included (we recommend a coin cell battery), from this tiny RTC’s low power consumption you can expect it to run 5 years or more. If there is a power failure, the built-in power-sense circuit will automatically detect and switch to backup supply, preventing an interruption in time-keeping. It works best with 5V power.
