The finger-tip sized ARM Cortex-M4F module with BT 5, BT Mesh, and 30 I/O The arrival of Bluetooth 5 was a significant leap forward for the IoT developer community, especially with its new Bluetooth Mesh functionality, which connects more devices and more sensors. Nearly four billion devices are expected to be shipped with Bluetooth technology in 2018. Bluetooth is driving innovation and creating new market ...

Karlsruhe Institute of Technology (KIT) researchers in Germany have developed a single-atom transistor that can reduce the power consumption of electronic systems significantly. The device is being developed by Professor Thomas Schimmel and his team at the Institute of Applied Physics (APH). The single-atom transistor switches electrical current by controlled repositioning of a sing ...

In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your heatsink design can handle it. Let's get started! Step 1: Watch the Video! The video gives you all the information ...

After making your PCB prototype the significant next step is placing your components on the printed circuit board. Depending on the sophistication of the prototype being developed, the number of parts to be used, and the parts layout; one might want to solder the components to the PCB board manually. Soldering components to a PCB might be a good idea, but might not be that efficient or even cheaper in the l ...

https://youtu.be/tERQQ0S8aJI Alright so soldering is pretty straightforward for through-hole components, but then there are times when you need to go tiny *insert ant-man reference here*, and the skills you learnt for TH soldering just dont apply anymore.Welcome to the world of Surface Mount Device (SMD) soldering, where components are placed on tiny pads, and solder on the pads is reheated to solder the co ...

This is my second project for LED Driver based on CAT4101 IC. The first project was for single White LED. This project has been designed to drive 3 channels of RGB LEDs with PWM signal which helps to create multicolor LED light. Arduino Nano is used to generate PWM signal for RGB LED and board has 3 tactile switches and Analog signal input to develop various RGB LED related applications. Each channel can dr ...

In this instructable I will show you how to make your own professional looking arduino shield. In the proses of designing the arduino shield I will use eagle.cad, arduino software & viewplot. First step in making a arduino shield is thinking of what you want it to be. depending on what your shield is going to be will vary the parts that you will need for it. PS: the picture is a sneek peek  on my new ar ...

Designing a PCB layout is a work of engineering art, includes placing components and routing them through different layers. So when you assign the same job for different engineers, each one would make it in his own way. But sometimes when working on a complex design some help may be necessary to finish the work. Autodesk EAGLE provides an autorouter feature which may assist you in many cases. The autorouter ...

Microcontroller demo boards such as the Arduino UNO are ubiquitous on Hackaday as the brains of many a project which inevitably does something impressive or unusual. Sometime someone builds a particularly tiny demo board, or an impressively large one. In the case of the board featured here, the Arduino is a gorgeous labor of love which can’t really be called a board since there is no PCB. Instead of the tra ...

There are plenty of techniques and components that we use in our everyday hardware work, for which their connection and coding is almost a done deal. We are familiar with them and have used them before, so we drop them in without a second thought. But what about the first time we used them, we had to learn somewhere, right? [TheMagicSmoke] has produced just what we’d have needed then for one component that’ ...

Ever want to say thanks to the nice person who just let you in line? I have thought a lot about that, and here is my solution. Things used in this project Hardware components Arduino MKR1000 × 1 SparkFun Bluetooth Modem - BlueSMiRF Silver × 1 Adafruit 4-channel I2C-safe Bi-directional Logic Level Converter - BSS138 × 1 Flexible Adafruit DotStar Matrix 8x32 - 256 RGB LED Pixels × 1 Adafruit 4-pin JST SM Plug ...

Open source is love, and so are hugs!   Things used in this project Hardware components Arduino MKR IoT Bundle × 1 Software apps and online services Telegram Story We all know that being without that special person in your life can be difficult, but what if you could send love and affection remotely over the Internet by just hugging a pillow? Now, we can't really send hugs... but what we can send is a ...
