Upgrading Firmware¶ There are three potential issues that arise from upgrading (or downgrading!) firmware from one NodeMCU version to another: Lua scripts written for one NodeMCU version (like 0.9.x) may not work error-free on a more recent firmware. For example, Espressif changed the socket:send operation to be asynchronous i.e. non-blocking. A discrete signal (digital signal) supplied to the NodeMCU is known as digital input. This signal can be generated manually using a push button switch. Push button switch is a switch which provides connectivity between its terminals when pressed. When the button is released terminals get disconnected. This tutorial is for NodeMCU on Arduino IDE. Class 9 physics chapter 1 notes
