While voice/speech-controlled embedded devices and systems are more popular thanks to the success of devices like the Amazon Alexa, their design is still quite a hassle due to the complexity of the engineering and algorithms involved. Since Alexa Skills became a thing, and Amazon opened up device APIs and SDKs that allow the integration of […]

Interfacing an ATmega32 microcontroller, this tutorial demonstrates the connection of a 4×4 (16-key) keypad with the ATmega32A microcontroller. Keyboards are recognized as essential input devices in electronic projects, providing a straightforward means to convey commands or directives to an electronic system. Necessary Components Hardware Components: ATmega32 microcontroller, 5V power supply, AVR-ISP programmer, JHD_162A LCD (16×2), […]

In modern compact electronic circuits, there are several components on a confined PCB area, and so, the electromagnetic effects induced from one component may affect the surrounding components. This disturbance is known as Electromagnetic Interference (EMI). The source of the radiation must be identified in PCBs to predict the EMC of electronic circuits. Electromagnetic compatibility (EMC) is the […]

This little processor board provides an economical and easy-to-use development platform for situations that require more power with minimal working space. With the M.2 MicroMod connector, connecting the […]

Numerous applications necessitate an external event to prompt an interrupt in the microcontroller, enabling it to respond accordingly. For instance, an interrupt might be initiated upon the detection of a fire by sensors like a temperature or gas sensor, or when a specific count threshold is achieved. Many microcontrollers, such as the ATmega32, are furnished […]

Guangdong-based electronics manufacturer, MeLe has been in the news a couple of times over the years for a number of their tiny but powerful intel mini processors-based desktop PCs. The company recently shared the beginning of sales of one of their latest creations; the MeLe Quieter 2, a fanless, small-sized PC based on an Intel Celeron J4125 processor. […]

Linear voltage regulators are used to maintaining a steady output voltage. They are step-down converters where the input voltage is always higher than the output voltage. The output voltage can be adjusted by external resistors. 78xx series is a very popular linear voltage regulator series. 78xx series, however, do not require external components for setting the output […]

When it comes to securing your system, there are always some loopholes that you’d want to know. In context to information technology, we have cybersecurity masters working on it to help organizations and corporates keep the information intact and keep the system safe from any external attacks. One such protective measure is trying the red […]

Introduction “Programming is merely one facet of a more extensive puzzle. To effectively address a problem, programmers must thoroughly understand and navigate the entire problem-solving process before diving into software development. This platform will outline the essential steps for problem analysis and solution implementation.” Following an introduction to the fundamental problem-solving process, this platform will […]
