Adjust the speed (try the values mentioned in the comment behind that code) and upload the sketch. The speed of the ESP8266 might be different from the speed set for EspSerial.begin(9600) in the sketch.Disconnect the USB cable from the breadboard power module and connect it again.

Check if the speed of the Serial Monitor matches the speed set in the sketch.

If it does not work, read the comments in the sketch carfully. The sketch should show something like this in the Serial Monitor: This example can initialize and test a new module. Test and configure the moduleĭownload the example sketch first_ESP8266_v2.ino Now connect a second USB cable to the Arduino Nano.

a 9V battery pack.Ĭonnect a USB cable to the breadboard power module and make sure the lights on the breadboard power module and the ESP8266 module turn on: * it is possible to use the 3.3V pin of an Arduino, if the Arduino is powered by a stronger power-source, eg. Take special care: for this type of breadboard power connector, never connect both wings to power sources! (USB power and a power adapter) You risk blowing up something, in the worst case your laptop! This is why we use a separate 3.3V power source: the breadboard power connector. Beware that the 3.3V from the Arduino is usually not sufficient* to power the ESP8266 module. TX from ESP8266 is connected to D2, RX to D3 of the Arduino (via 1K resistor). Now connect everything according to the scheme:ĭo not forget to add a GND wire (from Arduino GND to the blue power line on the breadboard). Insert an Arduino Nano on the other end of the breadboard:Ĭonnect wires to the ESP8266 (only to the pins we will actually use, the the schematic below):

Set both switches on the power module to 3.3V. Make sure the – (GND) connects to the blue lines and + to the red lines. Step 1: Connect and setup the ESP8266 moduleĪttach a breadboard power module to a breadboard. This guide assumes you already have some basic knowledge of Arduino and electronics and already did the “Getting started with Blynk” tutorial (for step2). In the second step we add some electronics to the circuit and show you how to control that via the Blynk app. This example uses an Arduino Nano, of course you may use an other type of Arduino, eg. For this we connect an Arduino to an ESP8266 module and connect it through Wifi (step 1). We are going to build a circuit that is connected to an app build with Blynk.
