Arduino 2009 and ESP8266 not responding error

I uploaded the following code on ESP8266

For the ESP8266 to act as a WiFi modem for your Arduino, the ESP needs to be running the standard Factory AT firmware, but you’ve overwritten that with your own firmware.
You need to restore the AT firmware to your ESP8266.

ESP8266-01S Not responding to AT commands

Hi guys this is my first topic, greetings to all… Down to business, I have connected my ESP8266-01S and managed to load and configure it with the examples using my Arduino UNO, but I don’t get to access it bt AT commands, all I get in response is this… (By putting ESP RST-GND) at BR74800. I´ve tried with and without external supply and same problem (external PSupply ATX600w, computer power supply 3.3v) my ESP8266-01S is working fine, because I can Load all examples to it like WiFi Scan using …

Also tried to wire the ESP Tx to arduino Rx and Rx to arduino Tx

That is the correct way.

Of course, you could save yourself a lot of hassle and choose better hardware to begin with…

Which board should I choose for my first Blynk project?

I thought I’d write a piece about my thoughts on the best hardware to use for your IoT projects if you’re just starting-out with Blynk. I did what many people do, started-off buying an Arduino Uno and uploaded some code to make it flash an LED. After about 10 seconds of watching the LED flash I was bored, and wanted to do more (I have a short attention span ). The next task was getting the Uno connected to the internet and I chose the Ethernet Shield route. After around 6 months of m…
