Bluetooth has been around for quite a while now. Being a common way to communicate with mobile phones, it was only natural to include this protocol in the Arduino arena. Bluetooth is typically a low power, medium range device, in fact it can reach up to 10 meters. Bluetooth operates on the same frequencies […]
The new digital SHT3x humidity sensor series takes sensor technology to a new level. As the successor of the SHT2x series it is determined to set the next industry standard in humidity sensing. The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor,
Description The MAX1720x/MAX1721x are ultra-low power stand-alone fuel gauge ICs that implement the Maxim ModelGauge™ m5 algorithm without requiring host interaction for configuration. This feature makes the MAX1720x/MAX1721x excellent pack-side fuel gauges. The MAX17201/MAX17211 monitor a single cell pack. The MAX17205/MAX17215 monitor and balance a 2S or 3S pack or monitor a multiple-series cell pack.
Battery-pack fuel gauge with SHA-256 authentication prevents pack cloning Continue Reading
Designing a DC/ DC converter that only consumes micro amps of current at no load can be compared to fueling a muscle car with lighter fluid – you may get it to work, but it won’t be easy. High efficiency at full load currents is commonplace in most modern DC/DC converters; however, achieving high efficiency

Duffy the mobile robot moves alongside you connected through a “light leash” and alerts you of objects around the path. Story 1) Background Audible Vision is designed to alert a person of objects around them. The project’s brain is the Arduino Uno, which is wired up with two IR Distance Sensors to tell you how
Parallel port I/O break out board designed for Hobby CNC, Routers and Motion controller , This Board is an easy solution to driver stepper Motor driver, AC Servo (with Step-DIR Driver) and DC servo (with Step-DIR Driver), The Board is compatible with various CNC software specially made for LPT port data out. The board has

Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added RS485 driver, or bought as assembled module. There is always the
Control any of the 55 RGB LEDs on the tree, let Santa twerk for you, control a model railroad, or display custom text on a LED dot matrix. Story Ooooops.. I think I made a mistake and accidentally posted the project twice, on “Arduino Create” AND “Hackster.io”. Please visit: this site to read about our

I wanted to try my hand at a true “DIY” project, designing and building my own micro quadcotper frame and writing my own firmware in C++. In this post I will describe the frame and build; in my next post I will talk about the firmware. Excluding stuff I had lying around the shop, (heat-shrink

The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But in the last several years PCM has attracted the industry’s attention as a potential universal memory technology based on its combination of read/write speed, endurance, non-volatility and density. For example, PCM doesn’t lose data when powered off, unlike DRAM,
