Is a project that i’m building a problem arise. It’s necessary to connect an Arduino to an ESP8266. But the arduino outputs are 5V and the ESP8266 inputs work with 3.3V. If it is connected directly, the ESP8266 burns. One possible solution is using a Logic Level Converter that converts 5V to 3.3V (this is the model used). This converter, on one side, receives 5V … Continue reading 5V to 3.3V Logic Level Converter
