I am working on an esp8266 and I am connecting it with Arduino Uno. I have programmed the Arduino but when I write AT command on the serial monitor it doesn't show anything.The connections which i have made are:
tx uno - rx esp rx uno - tx esp gnd uno -gnd esp vcc and ch_pd - 3.3v supply
I am using an external supply and not the 3.3v from the Arduino. I need help with this.
