IIC / I2C 1602 Blue Backlight LCD Display Module For Arduino (Blue backlight display)
Everyone loves the 1602-character LCD, it is cheap and works out of the box! But the need for 6 to 10 GPIOs is the pain :) It takes most of the GPIO of Arduino and other microcontrollers. Now with this I2C or Two wires interface LCD, you will save a lot of GPIO for your sensor and motor control.
This is a great blue backlight LCD display. As the pin resources of the Arduino controller are limited, your project may not be able to use a normal LCD shield after being connected with a certain quantity of sensors or SD cards. However, with this I2C interface LCD module, you can realize data display via only 2 wires. If you already have I2C devices in your project, you can still program this LCD with the correct I2C address. It is fantastic for Arduino-based projects.
Note: If the display is not clear (or blank), try to adjust the contrast level by tuning the onboard potentiometer.

DC 9V 1A Battery Button Power Cable Tieline For Arduino (9VDC Batt clip)
This is a very useful connector, on one end is snap for the 9V battery, and another end is the standard DC jack (2.1mm). If you are using a 9V battery to power your Arduino board this cable will be handy and perfect for you. The “center pin” of the DC barrel plug is positive and the outer barrel is negative meaning it is compatible with Arduino’s DC barrel jack. The battery snaps into the connector and has 110mm wires – just long enough to give you flexibility in battery placement, but not so long that the wires take up all of your extra space in your enclosure!

Need batteries? You will find our battery selection here
This battery box is designed for use as a nice switchable, portable power pack, and fits any four alkaline or rechargeable AA batteries in series. The body is moulded in black ABS Resin and has a slide on detachable lid which can be locked for extra security through use of a small provided screw. It even includes a very useful miniature on-off slide switch which is very handy for wiring to projects that don't have a switch! Connection is via two flexible stranded red (positive) & black (negative) 26AWG wire leads, which are approximately 150mm in length.
The four batteries are held in series, for a nominal output of 6V DC (6.4V when fresh, 4V when dead), and 4.8V DC for rechargeables (5.2V when fully charged, 4.4V when discharged). Using rechargeables will make this work nicely with nearly any 5V project, with alkalines you may want to put a 1N4001 in series to drop the voltage from 6V down to 5.3V.
