hi,
i have 2 questions here hope you guys can give me the answers
question 1
Is it possible to add buttons to the ez-b what i mean is i am thinking of adding a serial UART lcd to the ez-b would it be possible to change values on that lcd with adding additional buttons to the ez-b and how do i do that
question 2
i posted this question before but i couldn't get a clear answer so here i am again
i am new to lcd and lcd codes, could you give me and example text script for my lcd like i i want to write "hello world" how do i do that because i dont really know how to enter texts on ez script and it would be nice if you can tell me how to do tricks like moving "hello world" text to side to side or display diffrent informations
here is a link of the lcd i bought

hope i can get some answers now, cheers
See this Bumper Push Button Digital Switch post

2. As replied in your other topic, once I receive my LCD I will post you some examples, until then I have no way to check them. Unless someone else has the same LCD they will be unable to help as the commands may be different. Be patient and the examples will come, the manual for the LCD looks to be pretty straight forward.
Anything bigger than an LED use a TIP120/TIP122 Darlington switching circuit.
i wont use anything bigger than a led but i might use led stripes in the future do i need to purchase TIP120/TIP122 Darlington switching circuit for led stripes
by the way
you mean Set(d1,on) to turn it on and Set(d1,off) right? you wrote Set(d10,off)
Anything that draws more than a few mW of power needs the switching circuit. They are cheap and easy to make.
If in doubt build and use a TIP switching circuit. Basically LEDs are all that can be powered by the signal wire on the EZB.
i will make TIP120/TIP122 Darlington switching circuit this weekend so what i see i will plug led(s) to the 2 pin pin header on the circuit and servo lead will go in the ez-b but this time there is 3 cable instead of 2 if i connect servo lead to d1 port on ez-b "Set(d1,on) to turn it on and Set(d1,off)" would stay the same to turn it on or off right?
and with this circuit will i be able to use stripe leds and higher voltage leds too ?
