LCD model is 1602, temperature measurement is a thermistor, the wireless module NRF24L01 +,
Measured wiring is normal, pin no wrong, crystals is 16 m, plus a 1 m 22 p capacitance, resistance and really don't know where the problem is, the chip off board using seems to be 15 to 28 pin cannot work normally, the LCD is normal,
Just contact the arduino near white, comment, thank you,
(a few pictures, NRF24L01 + connection images here didn't answer, do before testing is also the function is not normal)
