When using ESP as standalone microcontroller, and if I uploaded a sketch written on the Arduino IDE, does that count as 'Arduino firmware' other people are referring to? Yes. "Firmware" is application code running on the microcontroller. On the Arduino IDE, uploading sketches onto the ESP8266 seems easy by just installing extra libraries from Board ...

Two ideas came to my mind, first is to connect each output to four digital pins and then do something like this: if(digitalRead(pinOne) == HIGH || digitalRead(pinTwo) == HIGH || ...){ do something } Or you can use an opamp or comparator for that purpose: simulate this circuit – Schematic created using CircuitLab In above configuration if any of the ...

It will not burn. The nodeMCU will only "pull" the amount of current (amps) it needs.

Generally, we specify DC power supplies as constant voltage sources. In order to do this, power supplies deliver more or less current as demanded by the load in an attempt to keep the voltage constant regardless of the load. When a constant voltage DC power supply specifies a maximum current, it is saying the power supply can only maintain the specified ...

The NodeMCU under the Arduino framework cannot do what you want. There are basically three methods for what you want: Configure the IP stack to enable routing - not possible in Arduino, and also requires configuration of your upstream router to work. Configure the IP stack to enable routing and Network Address Translation - not possible in Arduino, and I ...
