4. AardEnergy – Metering Chips In this Blog So far I have chosen sensors without much consideration of how the Arduino will handle the data. The plan is to use a meter chip with the Uno and to directly convert the sensor voltages (after suitable scaling) with the Due.  In this blog I will evaluate a number of meter chips for use with the Uno…ADE7753, ADE7763, MCP3905, MCP3909.

Hello,   Today I would like to share with you my second little project. Its an Arduino temperature logger which saves data on micro SD card and thanks to a short Python script it can also send data to Ubidots IOT application. The circuit itself is very simple, in order to complete it all you need is:   11 - jumper wires 1 - 4.7K ohm resistor 1 - DS18B20 temperature sensor 1 - SD card reader 1 - Arduino UNO   Here's the circuit's schematic:   Here's a video showing ...
03 AardEnergy – Current and Voltage Transformers   In this Blog I have a Current Transformer and a Voltage Transformer to evaluate. In this blog there will be a description of the sensors and some analysis of the signals as well as some measurements to assess performance.   See previous Blogs… http://www.element14.com/community/groups/arduino/blog/2015/11/23/1-aardenergy-kick-off--a-new-project http://www.element14.com/community/groups/arduino/blog/2015/11/26/2-aardener ...
Hello everyone,   I'm new here so I'm going to introduce myself. I'm Wojtek and I come from Poland, currently I''m 25 y.o. and I'm just starting my journey with Arduino. In the future I would like to share with you my projects and I hope you can provide some insight and constructive criticism.   Ok, so now lets hop into the project itself. It's rather basic because for now I don't have that many parts (just Arduino board, diodes, some resistors, tact switches and photoresistors). The ...
Few months ago we needed to realise an interactive experiment for kids, consisting in making light pass through a prism to be dispersed into a rainbow. The light was powered by a 220 V power outlet and must be controlled by kids looking at the experiment. Needless to say, the simplest solution was just to mount a switch on the power cord, such that the visitors can just switch the light on and off. In order for the experiment to be ready for next visitor, a better solution was evaluated to be a ...
