IoT Nixie Clock Shield for Arduino

Use your Arduino and build IoT Nixie Clock, Thermometer and Hygrometer. Nixie Clock Shield is designed for all Arduino boards (uno, micro, nano), but works best with the new board Arduino Nano 33 IoT.

Arduino Nano 33 IoT is fully compatible with the Arduino IoT Cloud. You can control the shield via the cloud, you can send data to the cloud then transfer it to e.g. Google sheets and visualize (e.g. temperature or humidity). You can also use the Alexa Amazon without any problems thanks to the dedicated Arduino skill.

And most importantly, you’ll find everything in the description below: sample program codes for different Arduino boards. Tutorials how to connect to the cloud, how to control nixie tubes, how to control the backlight, how to send data (e.g. temperature, humidity) to the cloud and finally how to integrate everything with Amazon Alexa.

#2 PART - CODING

Code Examples

Example program codes are divided into individual steps to better understand the functionality of the shield and encourage users to modify the code according to own ideas.
