##Installation

  • Download and install the Aduino IDE plus any drivers it asks too. You can use the free version with the JUST DOWNLOAD link. No need to donate money.

  • Install the NodeMCU "board" into the Arduino IDE:

  • Start Arduino and open Preferences window.

  • Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field and click Ok:

  • Open the Boards Manager Tools > Board > Boards Manager...:

  • Scroll down to esp8266 by ESP8266 Community, click More info and select version 2.2.0 then click install:

  • Click Close once it installed

  • Select the NodeMCU 1.0 board from Tools > Board menu and select NodeMCU 1.0 (ESP-12E Module):

  • Install the denbit library

  • Download the latest release of this repo

  • Sketch -> Include Library -> Add .ZIP Library... then select the file downloaded in the step above.

  • Rename ~/Documents/Arduino/libraries/denbit/src/default_config.h to config.h and edit its content to have the wifi access details and your denbit's name.

  • Mac users, if programming with a usb cable, install the driver from www.silabs.com (direct link).

Make it do something...

  • Connect the denbit to the usb port of the computer.
  • Select the Port the usb is connected to
  • On a Mac it will be /dev/cu.SLAB_USBtoUART
  • On Windows it will be COMM and a number so something like COMM4
  • Load the Blink "sketch"
  • File -> Examples -> Denbit -> Basics -> Blink
  • Compile (verify) the software: click the tick in the top left of the Arduino application...

  • wait while it compiles...

  • Upload the software: click the arrow in the top left of the Arduino application:

  • wait while it uploads...

  • The center light will be blue while it uploads.

  • When the Arduino window says "Done uploading" the green light will blink on & off
  • Change the Blink sketch so that delay(1000) is delay(500), then compile & upload again. The green LED will now blink twice as fast

Play with the Denbit Basic examples

Play with servos

Then use some sensors

Questions

How big is the Nrf nano PCB?

It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Nrf nano use?

21 parts, built around the NRF24L01. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Nrf nano KiCad files?

From the theapi/denbit repository on GitHub, at the commit this page was made from: the board is kicad/nrf_nano/nrf_nano.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Nrf nano design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
