KF2510 4-pin anti-reverse angle headers for i2c ports (2pcs)
These connectors go to the top side of the device and are used for connecting
expansion modules and other MAKERbuino’s or Gamebuino’s (
multiplayer
games!
).They’re just like all other connectors but with a special anti
-reverse function
so that you can’t swap the polarity and short circuit your game consoles when
connecting them with the multiplayer link cable.
1k ohm wheel trim potentiometers (2pcs)
Wheel potentiometers are very importan
t for regulating the
screen’s
backlight and dimming the
sound volume
.The potentiometers have B102 written on their back indicating that they have
1Kohm of resistance (10 * 10^2 ohms).
Resistors
Resistors are
standard passive two-lead electronic components that implement electrical resistance as a circuit element.
The resistors are used in MAKERbuino for all sorts of important tasks like
adjusting signal levels and regulating current flow.
Every resistor’s resistance is measured in
ohms
.
You can determine the resistance
of a resistor by using color code
–
reading a set of colored rings on the resistor
.
There are four types of resistors used in the MAKERbuino kit:
•
100 ohm resistor x1
This one is used when outputting sound to
MAKERbuino’s headphone jack.
Color code: brown, black, brown, golden
(*in some versions of the MAKERbuino kit, these
resistors might be labeled like this: brown, black,
black, black, brown or golden)
•
2.2k ohm resistor x1
This one is important for driving the transistor in the
MAKERbuino’s sound circuit.
Color code: red, red, red, golden
•
4.7k ohm resistor x2
These resistors are used as pull up resistors on i2c
lines (multiplayer and expansion ports).
Color code: yellow, purple, red, golden
•
10k ohm resistor x2
These are important for driving the LCD screen and connecting the microcontroller to the serial UART programmer (for connecting
the MAKERbuino to your computer).
Color code: brown, black, black, red, golden
