One of the first lessons many people learn when starting off learning practical, hands-on electronics is the need for pull-up resistors. Whether to prevent floating I/O pins on a microcontroller or interfacing two circuits via an open-drain design; pull-up resistors are an often necessary but rarely appreciated component. So why do we use pull-up resistors, can’t we just connect a wire to the Vcc supply of our device? What size resistor should you use?

In our case, we use NODEMCU ESP8266, but you can use any other type of ESP8266 with all pins exposed. In our program, we connect D0, D1, D2, and D3 in a circuit, which controls the relays. The relays are using 5V. ESP8266 is using 3.3V. To connect the 3.3V ESP8266 to the 5V relay module, we use one NPN transistor 2N2222.
