- | Checking the sensor is plugged into the right pins is easy: the connector plugs into the block of six pins near the centre on the back of the LCD screen. The correct pins are the top two pins, in the right column of pins, in that block of six pins. e.g:ย | + | Checking the sensor is plugged into the right pins is easy: the connector plugs into the block of six pins near the centre on the back of the LCD screen.

A simple solution is just to unplug the two wire cable sticking out of the LCD module! | A simple solution is just to unplug the two wire cable sticking out of the LCD module! | ||
However, if you want to use this feature, you can do this simple trick. Turning the connect 180 degrees, will make the metal side contacts face away from the other column of pins. Note that the JST connector they are using has three sockets, but only two are used. You need to make sure that the two wires are still connecting to the same two pins, but in this case we are effectively reversing the polarity. This is not a problem โ the sensor is a simple mechanical switch, so it does not matter which way electricity flows. | However, if you want to use this feature, you can do this simple trick.
