Getting Started with ESP8266 WiFi Transceiver (Review)

in this video I'll do a quick overview of the es 8266 module there's a good chance that you already heard about this wi-fi module this module is everywhere you can get one for less than $4 off eBay and let's face it compared to other Wi-Fi Alternatives in the market it's a no-brainer to get a couple of these ESP 8266 models just to play with them there's a link in the video description where you can buy one there are a few other versions of this module I'll be using the ESP 01 version V 090 which has two LEDs right there let's take a closer look of the pin oute on the top left pin is ground the bottom right pin is VCC and it's rate at 3.3 volts you also have RX and TX right there three GPI pins and the reset pin unfortunately this model is not breadboard friendly so we can either use some female to male jumper wires and connect your module like this or you can do an extra step and create a small adapter for your breadboard grab a piece of streetboard two either rows with four pins each and a 2x4 stackable leather then solder every everything together make sure you test with a multimeter short circuits before applying power to your model and this is the end result now it's much easier to access the ESP to 66 pins you can send 80 commands with an Arduino here's the code that you have to upload into your Arduino it's just a blank sketch and here's the circuit and no that's not a mistake the TX from the module connects to the TX in the Arduino and the RX connects to the RX you could also use one of these ftdi models and wire your circuit like that in this case the TX of the ftdi model goes into the RX of the esp8266 and vice versa remember that this module works at 3.3 volts so be careful when using it with an arduin or any ftdi programmer now let's send some AT commands plug your module to your computer open a Serial monitor now I'll apply power to my module and the message saying system ready prompts set your serial monitor to both new line and carage return and to a b rate of 96 keep in mind that I'm using the latest version of the firmware available at the time of recording this video some modules come with 1152 B rate by default and this is subject to change in the future you can watch my other video on how to update the ESP 8266 to the latest version of the firmware in that link below now we're all set type at and you should see okay you can type at plus gmr to see the version of firmware running in your module there are plenty of other commands to configure your module I'll leave a link in the video description with all the comments subscribe to my YouTube channel for upcoming videos using this module thanks for watching [Music]
