Esp8266 arduino no pins10/22/2023 At the time of writing this is the latest. In this example I am using IDE version 1.8.3. I presume you have the Arduino IDE either installed, or like me, are using the non installed folder version. You can’t use the Arduino IDE until you have added the ESP8266 core. The two talk to each other using serial.Īdding the ESP8266 core to the Arduino IDEįirst things first. I offload the web part of a project to the ESP8266 and use an Arduino, usually a Nano, as the main microprocessor. 10-bit ADC (this is a Successive Approximation ADC)įor small projects that require web connection it can replace an Arduino but for other projects it can be used to complement an Arduino perfectly and this is how I mostly use them.UART on dedicated pins, plus a transmit-only UART can be enabled on GPIO2.I²S interfaces with DMA (sharing pins with GPIO). ![]()
