Got your problem ,yes at a certain angle the words would appear to be floating in air or on water but it is right no problem with it if you are able to see words clearly when the LCD is straight in sight then it is fine.
Thanks John S and Delta_G you both got me Correct i have the answer from John what you say Delta_G about my way of connection?
Thanks James for Voltage Divider way i think with this way i will not need to modify the current controlled by the switch it will remain 12v to provide to the indicator bulbs and voltage divider will provide about 5v to analog inputs.
Im saying my idea is to run 5volt DC power(replacing 12v dc power) through switch used to control indicators on the bike so that input can be given to microcontroller from the switches and as per that input the Microcontroller can show symbols of LEFT-RIGHT on LCD and finally controlling the 12v bulbs used in indicators through TO-220 transistor.
The Motorbike has the switch like (left--OFF--right)
To connect to Arduino using Bluetooth module a pass is defined and one needs to conform to that pass to form a connection other things are same as wires as Bluetooth module like Blue smirf from spark-fun just acts as a pipe to receive and transfer.so the main problem is how a wii remote will send pass confirmation.
Actually im showing indicator symbols on LCD STN koIoB driver type one so for that to happen Uc must know when to show the symbols so as such the switches have to have 5v running in them so they can be interfaced with the Uc and transistor To-220 to switch high currents such as 12v dc that runs in bikes battery.
im interfacing the arduino with my bike , The bike's electrical stuff runs on 12v so to show indicators on the lcd i will be changing current flowing to indicator(left right) switch to 5v from the voltage regualtor and then the switch to arduino analog pin so that the arduino gets the command in analog pin and lcd could be driven and the indicator Bulbs are given power through TO-220 transistors.
The bikes indicator switch works like >> left--off--right
I think this would work pretty fine ,What you guys suggest/think?
