Join the IoT with your Arduino using the ESP8266 wifi module!
The ESP8266 wifi chip has proved very popular over the last few months, enabling us to add relatively cheap wifi to Arduino projects. This workshop will show you how to get the ESP connected to your Arduino board via Software Serial, and how to post Arduino DHT11 sensor data (temperature and humidity) to cloud servers such as emoncms.org and thingspeak.com, and, if you wish, send automated tweets from the Arduino based on sensor readings.
Aimed at people who have a bit of experience with Arduino, especially on the coding side (not for absolute beginners).
Bring your own Arduino compatible board with USB cable, your breadboard with a few jumper wires, and your laptop with the Arduino IDE installed.Â One ESP8266 (version ESP-01) and one DHT11 (temperature and humidity sensor) and wires are included in the workshop fee, see picture.
Workshop will take place at DSL, on Wednesday 15 April from 19:30 till 21:30.
Registration required via Eventbrite, max 10 participants.
- DHT-sensor-library-masterÂ (library to be installed in the Arduino IDE to use with the DHT sensor)
- 201504esp8266-workshop-sketchesÂ (3 example sketches for Arduino, 1 example sketch for ESP8266 as microcontroller)
- workshop slides on Slideshare
- the customised Arduino IDE for ESP8266 on GitHubÂ (to program the ESP8266 as microcontroller)
