Intermediate Arduino Course – 18 April


This class is for anyone who understands the basics of the Arduino Single Board Microcontroller and wants to take their projects to the next level.   You will learn to write sketches that fully take advantage of the capabilities of the Arduino.  You will also learn new ways make your Arduino communicate with other devices.

As part of the course, you will build an Arduino weather station with temperature, humidity and pressure readings. Data get saved to a SD card and will also be displayed in real time on a LCD screen. A RTC will keep track of date and time.



Please note that this is an intermediate course and those attending are expected to understand the basics of the Arduino, i.e.  the basic hardware, pin layout, basic programming with the Arduino IDE and connecting LED’s, switches and potentiometers.

Internet of Things Build Project using the ESP8266

WiFi Serial Transceiver Module
The last few weeks we’ve been playing with the ESP8266, an Arduino and some sensors and thought we could have a build at H4H for those who want to learn more about this amazing little module.
Build description:
We will be showing you how to interface your Arduino with the new ESP8266 wifi module and send data from sensors connected to the Arduino to a server on your LAN or to one of the IOT web services, e.g. ThingSpeak.
For this course we will be using the ACS714 current sensor and/or the DHT11 Digital Temperature and Humidity Sensor, but feel free to bring any sensor you like.
On the server side we will run a simple socket program to show how the ESP connects and sends data.
Then we’ll setup a Thingspeak channel and show you how to send data to it.
We will only be prototyping this, in other words, the final product is breadboard with jumper wires to connect everything.
Future courses will build on this to make a more permanent product and will consist of designing and etching circuit boards, independent power supplies, housing your product, more advanced python to display graphs of your data, etc.
You need to be familiar with the Arduino environment, e.g. IDE and how to upload sketches, etc.
Equipment used in the build
– ESP8266 serial wireless module
– Arduino Pro Mini 3V3 (The ESP8266 is not 5V tolerant)
– CP2102 USB Programmer Module (This serial module talks 3.3V)
– ACS714 -30A to +30A current sensor (1)
– Breadboard
– F-F and M-M Jumper wires
– Your own laptop/computer with Arduino IDE installed.
(1) If you use the ACS714 you will also need a 220V plug, adaptor and about 1M of cable.
It will be on Tuesday evenings, probably starting middle of February.
Complete the form below if you are interested. The cut-off will be end of January.
