hi people, im noob, and i want to make a transducer reader, that send data to other arduino with a lcd 128x64b.
for my idea i have 2 arduino, 2 nrf24, and 1 lcd of 12864b v.2.0
i wanna know if anyone can help me with a example code, for read analog inputs (A0,A1,A2,A3), and send with the nrf24 to other arduino and show in the lcd.
i see this with 1 sensor but with lcd of 16x2, and i dont know if i can use the same code for work with my lcd of st7920.
please any help is appreciate
this is my global project
this is the transducer connections, i use potentiometer for now, because dont have the bench for test the transducer and i wanna simulated the signal.
this is the part of lcd + nrf24 that i dont know how connect
Tell us what you do know and what you have tried. Easier to work from there than all the i don't know and cant.

hi for the moment i make all the connections of the project on fritzing, and read, (in this forum), how integrate my lcd ST7920 with a transceptor nfr24l01, (spi in software mode), but my principal problems is that i dont know of programming, i tried to use ardublock or mBlock, but dont have the libs fot the lcd st7920 and the transceptor, i can modify some lines in the IDE, but i cant understand the commands.
i only wanna that the first arduino read the analog inputs of A0, A1, A2, A3, and send this info for second arduino with the lcd.
can programming in ardublock or mBlock without the lcd and transceptor librarys?
i upload the fritzing project for if anyone have a help.

Have a look at this Simple nRF24L01+ Tutorial.
Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.
The examples are as simple as I could make them and they have worked for other Forum members. If you get stuck it will be easier to help with code that I am familiar with. Start by getting the first example to work
There is also a connection test program to check that the Arduino can talk to the nRF24 it is connected to.
A common problem with nRF24 modules is insufficient 3.3v current from the Arduino 3.3v pin. The high-power nRF24s (with the external antenna) will definitely need an external power supply. At least for testing try powering the nRF24 with a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND.
