I am asking because if you connect the same battery's + and -, huge current flows and shorts the battery. Why doesn't this happen, when you connect one battery's + to others -? I feel like I am missing some major point here.
We envisage that these inexpensive sensors can be built and maintained by interested hobbyists. Our goal is not to develop the world's most accurate sensor, but rather a device which at a glance tells us if it's a good idea to spend time outside.
Once upon a time there were hifi micro sets (casssettes, CD's and mini-disc) and portable radio's. However in the land of technology it began to change and now we use streaming services like Spotify.I wanted to build a micro set based on Raspberry Pi...
I use an Arduino Pro Micro as microcontroller to send the actions. It's a small board, 7x4 cm. The wheel for the rotary encoder it's 3d printed, but you can use any knob you have.
In this guide, I shall outline the steps to be followed to get yourselves a smart LED strip on a budget. This strip can be controlled using both the Google Assistant and Amazon Alexa either by voice via the respective party's smart speakers or from the...
