芯片或SOC上的系统是一个集成电路，该电路结合了计算机上存在的大多数组件。顾名思义，它是在硅芯片上制造的整个系统。SOC的美在于，它将所有组件都集成到单个基材上。在半导体中，底物…

A real-time clock (RTC) is a computer clock to keep time and is one of the more popular microcontroller features. Microcontrollers without a built-in RTC require an external RTC chip for keeping time. Typically, mid-segment to high-end microcontrollers have a built-in RTC because time-keeping is necessary for several embedded applications. RTCs count seconds, minutes, hours,…

In this article, we will learn how to choose a battery according to the specifications and requirements of your application. Some applications need more power and some need to be cheap with less power. There are various factors and parameters that to consider when choosing the best battery for your application. No one battery is…

A single cell is not sufficient for some devices. To achieve desired voltage, the cells are connected in series to add the voltage of cells. To achieve the desired capacity, the cells are connected in parallel to get high capacity by adding ampere-hour (Ah). This combination of cells is called a battery. Sometimes battery packs…

机器人源于捷克语单词“ Robota”，意思是奴隶或任何可以帮助其主人的机械项目。机器人是机械设备，有助于对人类执行特定的任务。“机器人”一词可用于配备基于软件的智能来执行特定物理任务的任何机械设备。机器人汽车或机器人车是许多机器人设计之一，这些机器人设计旨在进行进行物理任务。这种机器人的运动本身涉及功率的应用和电动机的使用。在制作这样的机器人时，需要在负载（机器人的重量），电池和电动机之间保持平衡。

The battery stores electrical energy in form of chemical energy and the chemical energy again able to convert into electrical energy. The conversion of chemical energy to electrical energy is called discharging. The chemical reaction during discharge makes electrons flow through the external load connected at the terminals which causes the current flow in the…

A battery is an electrochemical device that can store energy in the form of chemical energy. It translates to electric energy when the battery is connected in a circuit due to the flow of electrons because of the specific placement of chemicals. For more information on how batteries work, you can read the article which…

A watchdog timer is an internal or external timer that monitors a microcontroller’s program to ensure the application remains operative without failure. It serves as a safety feature in critical applications by monitoring the microcontroller’s output signal. The watchdog can operate in two modes: Timeout mode – the timer establishes the microcontroller is not working properly if it…

经过Aaron Bauch, Senior Field Application Engineer, IAR Systems Design specifications require the ability to update a device’s firmware in the field dynamically. This is done commonly via a bootloader. Designing a bootloader, however, is challenging as it must meet various requirements. For example, the mechanism for getting the new application into the MPU is…

Brain wave is a common term that can be easily found in Science books/newspapers or can be heard from doctors and researchers. Have you ever thought what exactly Brain waves are? How are they produced? What is their role in day-to-day life and how do they affect us?Let me take you through a roller coaster ride exploring Brain Waves alongside its features, types, characteristics, and other details. Brain Wave is among the few technologies the world is researching these days. There are a lot of potential techniques in this field and it may solve many of our future problems.

Now that we know the basics of Brainwaves and the sensor on which we are working, it’s time to learn about the brain of this brain wave sensor. The main part of any device is its processing part and in the case of Mindflex Sensor, it’s the NeuroSky EEG Chip.Let’s move on to the details so as to know what the chip contains and how does it work.

Till now we have seen the working of the EEG chip and we are also aware of our sensor. So now it is the time to do some experiments and gain some practical knowledge on brain waves.In this first experiment, we will try to hack the EEG signals. For this, we need to make some arrangements so that we can easily measure the signals.
