i bought 2 esp modules (ESP-05 and ESP-03), i've tried to use them with arduino ide and also with realterm , when i send a command i have no feedback from the module in the serial monitor , it doesn't print anything on the screen. i've tried with an external power source for the current and different baud rate and arduino boards but nothing every command i sand i have no feedback from the module please help me i don't know how to solve this

SOLVED : i made a voltage divider in input , now it works , the problem was that arduino output is 5volts and modules want 3.3v
