The main goal of this circuit is to save energy. So, I am not going to talk about arduino because the board itself has unnecessary power overhead for a final product. It is great for development. But, not very good for final projects running on batteries. I will use one for my POC but, to save energy, using the Atmega328 standalone will give you better results.
Here’s an application to control the brightness of an RGB LED strip wirelessly (via Bluetooth) using a smartphone. The whole project is presented in a dedicated Bluetooth shield for Arduino and a RGB shield. The Bluetooth Module You’ll know already that the market is full of different Bluetooth modules: these modules are all based on…
This is my the first mechanical keyboard project. And this will be for daily usage. Although the possibilities are almost endless, I limit myself to the basic functionality: An ergonomic keyboard with mouse functions. While searching for parts I came across a new type of switch. A low-profile version of the Cherry MX…
Let’s build the Dashboard to optimally manage our network of IoT Antennino devices connected through the dedicated Gateway module. After having described the hardware gateway for the Antennino modules and having combined it with a Dashboard based on the ThingsBoard software ideally, with which to govern a network for the IoT, in this article we…
3D printing is a cutting-edge technology that enables the creation of three-dimensional objects through a layer-by-layer process. This method of printing starts from a digital model file and uses bondable materials such as metal or plastic powders to produce the final product. The printed object can have any shape and geometric characteristics, making it a…
Arduino Team is pleased to invite the open source community to join the Arduino Day 2019 on Saturday, March 16th! Arduino Day is a worldwide celebration of Arduino’s birthday. It’s a 24-hour-long event—organized by both the community and our team—where those interested in Arduino get together, share their experiences, and learn more about the platform….
Makes Raspberry Pi suitable to be used in “professional” environments, sports a power source, an UPS, a RTC clock, a watchdog function, RS232 and RS485 converter and a buzzer. All in one. In the previous posts in which we presented different solutions – and above all in the professional daily work – we…
