▷ The Social Cognitive Theory #SCT applied to reduce sedentarism in citizens

➡️ #SCT #SocialCognitiveTheory #Sedentarism Sedentarism is a growing concern in today's society due to its negative effects on health and well-being. However, the Social Cognitive Theory offers a solution to reduce it through a series of strategies based on human behavior. ➡️ According to this theory, human behavior is influenced by social perception, that is, how we perceive others and how they perceive us. In the case of sedentarism, one way to reduce it is through the creation of a social culture that values and promotes physical activity. ➡️ One way to achieve this is through education and awareness about sedentarism, physical activity, nutrition, quality of life, among other health-related aspects. Creating awareness campaigns about the importance of maintaining an active lifestyle can help influence social perception and motivate people to change their sedentary behavior. ➡️ Another strategy is the creation of programs and physical activities that are accessible and attracti...

▷ SD3031 Precision #RTC Module for #Arduino

➡️ #RTC #Arduino #DFRobot About this item This real-time clock #RTC module uses the SD3031 chip, which has an integrated crystal oscillator and temperature compensator. This provides high-precision timing and stability. At a temperature of 25 °C, the accuracy is maintained at ±3.8ppm (±0.32832 seconds/day). The SD3031 can be powered by button-cell batteries. This allows for accurate timing even when the main power source is interrupted. The RTC keeps track of seconds, minutes, hours, days of the week, dates of the month, and months and years. It also automatically adjusts the date at the end of each month and includes leap year corrections. The SD3031 has a built-in 70-byte SRAM for low-power data storage. Please note that due to recent air cargo regulations, special items such as batteries, magnets, and liquids are strictly audited for air transport. As a result, the RTC module does not come with batteries. You will need to purchase them locally. The button cell model that...

▷ What is the MQTT protocol?

➡️ #MQTT #IoT #SensorNetwork The #MQTT (Message Queuing Telemetry Transport) protocol is a lightweight communication protocol designed to facilitate communication between IoT (Internet of Things) devices. It was developed in 1999 by Andy Stanford-Clark and Arlen Nipper and has become one of the most widely used protocols in the IoT world. ➡️ How does MQTT work? MQTT works with a publish/subscribe model, in which devices connect to a centralized broker or server and send and receive messages. The protocol uses an asynchronous communication model, which means that devices can send messages at any time, without needing an immediate response. In addition, MQTT uses a "topics" model, which allows devices to publish and subscribe to messages related to a specific topic. For example, a device could publish messages related to the "temperature" topic, while another device could subscribe to that same topic to receive the messages. ➡️ What are the advantages of MQTT? MQTT...

▷ The Importance of Soft Processors in #FPGAs for Customized Digital Circuits

➡️ #FPGA #VHDL #SoC # System-on-Chip #Processor #SoftProcessors #DigitalCircuits #DigitalSystems FPGAs (Field-Programmable Gate Arrays) are programmable electronic devices that allow for the creation of customized digital circuits.
