Check to make sure your kit comes with the following parts.Sometimes we make mistakes so double check everything and email [email protected] if you need replacements!
1) Resistors
There is a total of 5 resistors in this kit. For resistors labeled R1 and R2 on the PCB, they are 1/4W 5% 4.7K resistors (Yellow, Violet Red, Gold). For resistors labeled RED and BLUE on the PCB, they are 1/4W 5% 220 ohm resistors (Red, Red, Brown, Gold). For the resistor labeled GREEN on the PCB, it is a 1/4W 5% 330 ohm resistor (Orange Orange Brown Gold).2) Potentiometer
There is one 10k trim potentiometer. This part will go in the spot labeled Contrast, near the RESET button. Note: The pot may be blue instead of orange.
3) Pushbuttons
There are a total of 6, 6mm tactile switch pushbuttons. These will be used in the UP, DOWN, LEFT, RIGHT, SELECT, and RESET locations on the PCB.4) i2c Port Expander Chip
There is one of these MCP23017 i2c (16 input/output) port expander chips in the kit. This is how we are able to only use 2 Arduino pins to run the entire LCD and buttons. Click here for more info on this chip.5) Male Header Pins
There are two strips of 36 male header pins in the kit. These will be used to attach the shield to the Arduino, as well as attach the LCD to the PCB.
Additional
You'll want an LCD to place into the shield. This isn't included by default since a lot of people already have LCDs they may want to use. (We do sell these in packs however so chances are you did get an LCD with your order).You can also use 16x2 LCDs or even OLEDs that are the same size that do not have an RGB backlight, or have no backlight at all.
We carry Negative type or Positive type LCDs.
