Dear Sir,
I have an arduino uno r3 and the ESP8266 ESP-12e (by WangTongze).
Basically, I want to send 2 numbers from my arduino to my laptop, I haven't reached there yet.
I am trying to see if ESP8266 is working. I am sending AT commands but the ESP8266 is not responding.
I am using the LM1117 to get 3.3 V.
Here is the way that I have my connections:
Arduino ESP8266
Tx Tx
Rx Rx
Gnd Gnd
5V to the input pin of LM1117
The output pin of LM1117 is connected to the Vcc and CHP_EN of ESP8266
The Gnd pin of LM1117 is connected to the Gnd of Arduino and ESP8266
Can you please tell me what I do wrong?
I would very much appreciate your help.
