Arduino and MPL3115A2 sensor data to Thingspeak example
In this example we connect an Ethernet shield to an Arduino, we then connect a MPL3115A2 sensor to this and we will send the values to Thingspeak
Sending temperature data to ubidots from an Arduino
The SHT21 is a low cost humidity and temperature sensor. Its an I2C device so again is very simple to connect to any arduino. In this case we will send sesnor data to ubidots The SHT2x sensors contain a capacitive type humidity sensor, a…
Sending SHT31 sensor data to sparkfun using an Arduino
In this example we will take the SHt31, read the temperature and humidity and send this data to an online IoT platform, in this case we will use sparkfun data. To achieve this we will need an Arduino Uno with an Ethernet shield fitted and…
Arduino web server showing DHT11 data
In this example we will use a DHT11 sensor and display the humidity and temperature on a web page. You can use any temperature sensor but the DHT11 is fairly low cost and there are libraries written for it, it comes in modules and even if…
Arduino ethernet shield read switch example
In the previous examples using the Ethernet Shield for the Arduino we controlled an led and an rgb led using pins as outputs but you can also easily monitor the state of an input, in this case we will use a switch Basically it will be a web…
Control an RGB LED from a Web browser with an Arduino
This is similar to the led example but this time we attach an RGB led The example is similar to the Control an LED from a Web browser with an Arduino example, so we won't dwell on the details of that example too much but we will crack on…
Control an LED from a Web browser with an Arduino
A simple way of adding network access to your Arduino Uno and Mega is the Ethernet Shield, there are a few clones out there but they all generally work the same way. The Arduino Ethernet Shield allows an Arduino board to connect to the…
A NodeMCU board and Arduino development
The ESP8266 is a low-cost Wi-Fi chip from Chinese manufacturer Espressif The ESP8266 commonly is found as a small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands.…
Wemos D1 hardware
The wemos d1 is an Arduino Uno-like wifi board based on ESP-8266EX. You can use the Arduino IDE, NodeMCU and there are other development environments available The ESP8266EX is among the most integrated Wi-Fi chips in the industry.…
