Forgive me if the answer to this is blindingly obvious but I seem to be stuck on what must be virtually lesson one.
I have constructed a few Arduino circuits (leds, potentionmeter, temp and humidity sensor) so I have a grasp of the basics.
I am trying now to connect a LCD display of 16 characters by two lines. The file included with the Arduino software in the example folder seems short of a bit of information.
It gives details of connections for pins RS, E, D4, D5, D6, D7 and R/W but then says
10K resistor without saying where or to what is is connected
"ends to +5v and ground". What does "ends" mean? Is that the VSS pin at one end and the K pin at the other and if so which end gets the +5v?
It also says "wiper to pin V0". I guess that means I need to include a pot in the circuit somewhere. Is that to control brightness of the display?
I clearly need to learn about libraries if I am to progress. Can anyone recommend a book that will give me an insight into them?
