Power module using boost, charge and protect

 1.BOOST: The boost is the second most common non-isolated typology, in terms of units sold and functioning, and a lot of that is thanks to LED drivers, especially mobile devices. The boost is a logical next step to analyse after the buck, and it’s the second of the three most basic DC to DC typology. ... Continue Reading →

PCB Etching Process

Below are the steps for PCB Etching process: Step 1:- Take printout of PCB layout Make sure that the printout is made on the glossy side of the paperLaser printer has to be used so that the impression can be transferred onto the copper plate during heating process Step 2:- Cutting the copper plate Step...

IOT how it works?

The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. A complete IoT system integrates four distinct components: sensors/devices, connectivity, data processing, and a... Continue Reading →

Commonly Used Electronic Components

The most commonly used components for any DIY project are: ResistorCapacitorInductorBJT’sMOSFET’sDiodesMotorsLDRLED 1.Resistors: Resistor is an electrical component that reduces the electric current. The resistor's ability to reduce the current is called resistance and is measured in units of ohms (symbol: Ω). If we make an analogy to water flow through pipes, the resistor is a...

MAX 232

The MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available. These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5µW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended... Continue Reading →

Different Controllers and their respective Software (IDE)

PIC (Peripheral Interface Controller): These micro-controllers are found in many electronic devices such as phones, computer control systems, alarm systems, embedded systems, etc. Every PIC micro-controller architecture consists of some registers and stack where registers function as Random Access Memory ( RAM) and stack saves the return addresses. The main features of PIC micro-controllers are RAM, flash memory, Timers/Counters, EEPROM,... Continue Reading →

Temperature Sensor LM35

Temperature is the most often-measured environmental quantity. Since most physical, electronic, chemical, mechanical, and biological systems are affected by temperature. Certain chemical reactions, biological processes, and even electronic circuits perform best within limited temperature ranges. Temperature is one of the most commonly measured variables and there are many ways of sensing it. Temperature sensing can be done... Continue Reading →
