  • Class17 – Arduino

    GPIO in/out on the Arduino. Presentation

  • Class18 – Arduino 2

    Arduino. We have seen it running last week.  But let’s examine in some more detail how it works. C language. Libraries. Simple GPIO manipulation. Sketch structure. And one more peripherals: RC servomotor RPi vs Arduino: They both control GPIO things. So why is an Arduino NOT a Raspberry Pi? … and why can’t we easily use Blynk with Arduino for remote control? PPT.  

  • Class19 – Arduino 3

    Adding ultrasonic range-finder  and oled display to Arduino. PPT

  • Class20 – ESP8266 Intro – a variant arduino

    ESP8266: GPIOs like the arduino IDE? – the same arduino IDE But with easy WIFI connection included Today: Simple GPIO control. OLED display PPT Reference:  https://arduino-esp8266.readthedocs.io

  • Class21 – Wifi on the ESP8266

    Lua interpreter – the easy environment for creating your own projects on ESP8266. Today: Install lua interpreter Configure your blynk token Load lua files to ESP Connect ESP to wifi router Control ESP8266 by BLYNK on your phone PPT

  • Class22 – Blynk, esp8266 and real-time

    Using library boilerplate (that we barely need to stay worrying about)  to get main things done: Startup Wifi connection Establish true time Library for each “device” you want connected (Temperature? Alarm button? Oled display? etc) Then each time a very simple “project” file to tie the parts together, to make YOUR PROJECT do what you want. PPT eSuite-Manual-A  

  • Class23 – Esp8266 “Projects”

    More BLYNK projects on the ESP8266. Servomotor control. Pitch & Roll. Water tank pump control from level sensor. And “creative” multi-use of a button. PPT Esuite Manual – next instalment

  • Class24 – Analog inputs

    A brief look at using analog inputs. But mostly consolidation/revision of last week.   PPT

  • Class25 – Thingspeak – plot that data

    Post your data (Temperature? Voltage? …) regularly to Thingspeak, And then read your data as graphical view. PPT  

  • Class26 – Deep Sleep to save Battery

    If some example battery could keep an ESP8266 running for 3 hours, then extending that battery life to maybe 200 hours might be very handy. Deepsleep presentation

  • Class27 Logging

    Logging regular data on the ESP8266 itself.   PPT

  • Class28 Webserver

    Running the ESP8266 as a simple webserver. Control relays, read buttons, read status all from your browser.   PPT

  • Class29 LED Matrix Displays

    7-segment and 8×8 LED displays.   PPT:

  • Class30 MQTT

    MQTT is an internet “connectivity” protocol for Internet of Things, used widely We will use MQTT Apps on smartphone and PC to control our IoT gadgets. For example,  a convenient MQTT app on android is MQTT Dashboard. MQTT setup Class PPT rev2

  • Class31 Forth

    Time for something completely different! Raspberry Pi and forth. PPT AND THAT WAS THE LAST CLASS FOR KINKY KOMPUTING 2017

Raspberry Pi, Internet of Things, Cloud and Code
