En esta lección, mostraremos cómo usar el escudo WiFi ESP8266 de OSOYOO y la placa básica de OSOYOO (totalmente compatible con Arduino UNO) para trabajar como servidor web y mostrar el mensaje “Hola mundo!”, en un navegador.
Placa básica de OSOYOO x 1
Escudo WiFi OSOYOO ESP8266 x 1
Simplemente, inserte el escudo WiFi OSOYOO ESP8266 en la placa básica de OSOYOO y use un tapón de puente para conectar E_TX a D4 y E_RX a D5, como se muestra en la siguiente imagen.
Nota: Si desea utilizar el escudo WiFi anterior en una placa Leonardo en lugar de la placa básica de OSOYOO, tendrá que quitar el tapón de puente entre D4 y E-TX. Luego use un cable puente para conectar E-TX al pin D8 en la placa Leonardo. También deberá establecer el pin RX de Software Serial en D8 en lugar de D4 en su código de programa.
Paso B) Se requiere la biblioteca Wifi ESP para ejecutar el código de esquema del escudo OSOYOO ESP8266. Si ya ha instalado esta biblioteca, omita este paso.
Luego, en su IDE, vaya a Sketch> Incluye Library> Add.ZIP Library y seleccione el archivo WiFiEsp-master.zip que acaba de descargar. Cárguelo en el IDE.
Paso C) Descargue y edite el archivo esp8266-lesson1.ino. Descargue el esquema desde https://osoyoo.com/driver/wifi-iot/lesson1/esp8266-lesson1.zip y descomprima el archivo. Haga doble clic en el archivo esp8266-lesson1.ino, que puede editar en el IDE.
Paso D) Conecte la placa básica de OSOYOO a la computadora mediante un cable USB.
Paso E) Abra la IDE y elija el tipo de placa correspondiente y el tipo de puerto para su proyecto.
Board:”Arduino/Genuino UNO”
Port:Elige el puerto serial de tu placa principal
Paso F) IDE: Haz clic en Archivo > Abrir > Elige el código “esp8266-lesson1” y carga el sketch en tu IDE.
En el sketch, encuentra las siguientes líneas:
char ssid[] = "******"; // your network SSID (name)
char pass[] = "******"; // your network password
con el SSID y contraseña correcto de tu WiFi. De lo contrario, tu proyecto no podrá
conectarse a Internet.
Después de cargar el sketch en el IDE, abre el monitor serial en la esquina superior derecha del IDE.
Verás el siguiente mensaje.
Desde el monitor serial, puedes ver la dirección IP de tu placa OSOYOO Basic en el círculo rojo (en la imagen de arriba, 192.168.50.116).
Luego, usa tu navegador para visitar el sitio web http://192.168.50.116. Verás el siguiente resultado.
Following directions step by step receives an ERROR “WiFi shield not present” – Also when using this link next to that part above “https://osoyoo.store/products/esp8266-wifi-shiled-osoyoo-wifi-internet-of-things-learning-kit-for-arduino-uno?variant=31955252215919” you get a 404 Web Page Not Found Error. Why are things sold that don’t work when the directions are followed as they are presented and why can you not keep your site working for links to try to fix the issue? Not a thing here for what to do with regards to it NOT PRESENT, what do I do from here?
The correction is as follows: when the items arrived the two jumpers on the shield were on the other 6 pins not the correct ones. You have to look at it real close because the first image you show has ZERO Jumpers, the second image has jumpers that can been seen as bein g the lower set of 6 not the top set but only if you enlarge the image to see this. The image with the circle on it needs to be set to an angle not straight down and use some better colored jumpers that can be seen. The best thing I have to say though is this. You are the fourth “set” for noobies I have purchased to follow and you with a few minor things have actually worked. The other three Failed miserably due to libraries not found in the version of IDE they have you download, I am using 1.8.10 as shown in the image. Granted some of the benefits of the never 2.3.0 version are missing yours works. I can’t wait to move on and act like a noob to see if the rest of your classes work. I believe the only thing that was going to cause an issue I have fixed and have great expectations for the rest.

We have updated the article. thanks for your help!
