PRÁCTICA 6: Creamos Un Museo

En esta práctica vamos a idear una alarma de un museo de diferentes formas. Una será por sensor de luz por si el ladrón va con linterna, otra por un interruptor por si el ladrón lo pisa...Siempre que la alarma salte parpadearán dos luces y sonará un zumbador para que los policías puedan pillar al la...

Arduino Cinque – The RISC-V, ESP32, WiFi, Bluetooth Arduino

This weekend at the Bay Area Maker Faire, Arduino in conjunction with SiFive, a fabless provider of the Open Source RISC-V micros, introduced the Arduino Cinque. This is a board running one of the fastest microcontrollers available, and as an added bonus, this board includes Espressif’s ESP32, another wonderchip that features WiFi and Bluetooth alongside a very, very powerful SoC.

Details on the Arduino Cinque are slim at the moment, but from what we’ve seen so far, the Cinque is an impressively powerful board featuring the RISC-V FE310 SoC from SiFive, an ESP32, and an STM32F103. The STM32 appears to be dedicated to providing the board with USB to UART translation, something the first RISC-V compatible Arduino solved with an FTDI chip. Using an FTDI chip is, of course, a questionable design decision when building a capital ‘O’ Open microcontroller platform, and we’re glad SiFive and Arduino found a better solution. It’s unknown if this STM32 can be used alongside the FE310 and ESP32 at this point.

We’ve taken a look at SiFive’s FE310 SoC, and it is an extremely capable chip. It was released first at the HiFive1, and our hands-on testing revealed this is a chip that outperforms the current performance champ of the Arduino world, the Teensy 3.6. Of course, with any new architecture, there will be a few problems porting the vast number of libraries over to the FE310, but SiFive has included an Arduino compatible SDK. It’s promising, and we can’t wait to see SiFive’s work in more boards.

Arduino IDE for Building Compiling Environment of ESP32

Arduino IDE is simple!There are many development platforms for ESP32 (ESP-WROOM-32). In some situations, using Linux or cygwin in Windows are quite intimidating for beginners. Using Arduino IDE is a more user-friendly approach. ​Add The Board URL to Arduino IDE Open Arduino IDE (I am using versio...

Pedometer for Calorie Conscious Hamster Owners

The Arduino has inspired many a creative projects that can be beneficial to humanity. The Arduino Hamster Wheel Pedometer by [John Mueller] on the other hand is a creation that is meant for the cute furry rodent pets. When [John Mueller]’s daughter wanted to keep track of her hamster’s night-time strolls, her maker-dad saw it as an opportunity to get her involved in technology. The project consists of a hamster-wheel with a magnet that triggers a reed switch on completing a revolution. The entire assembly is custom-made and [John Mueller] does an excellent job documenting the build with a lot of clear images.

The wheel is affixed to a shaft with a ball bearing at one end and the entire thing is mounted on the side of the cage so that it can be removed with ease for maintenance. The reed switch is embedded in the wooden mounting block such that the connecting cables pass from inside the assembly. This prevents the hamster from coming in contact with the cabling or damaging it in any way. An LCD and the Arduino Uno are placed outside the cage and are used to display the revolutions of the wheel as well as the equivalent miles travelled.

The code for the Arduino is also supplied for anyone who wants to replicate the project and the video below shows the working of the project. The project could also be extended to count calories burned as well as running speed. This project is a prime example of how technology can be used to assist and is similar to the IoT Hamster Wheels that tweets every movement of the Hamster Life.
