How can I learn to code an arduino, PIC or nodemcu?

Question

I want to learn how to code these microcontrollers but I don't have a computer. Is there any way or app where I can learn it?

Answer 1

If you have an Android phone/tablet you can use ArduinoDroid

Answer 2

nodeMCU can be programmed with C (using the Arduino IDE), or using Lua. I'm familiar with C, but found Lua to be easy enough to learn and utilize on the nodeMCU board. If you're familiar with Python, Lua won't be much of a stretch. I've yet to find a way to load Lua programs into the nodeMCU using Android, but it wouldn't surprise me if that came along soon.

I also have experience with PIC microprocessors. They are generally programmed in C, and Microchip has a great IDE available for free. But you'll definitely need a computer, and a programmer (hardware device) for the microprocessor.

In other words, if you focus on learning C or Lua, you'll be more than half way there.
