Transistor and how to use it in the circuit

A transistor is a three-pin electronic component which its main function is to pass the current from two pins according to the other pin (along with current amplification). Transistors have different types, but we are going to examine the bipolar type here. The two pins which the current passes are called the emitter (E) and…

Capacitor and how to use it in the circuit

In most of the books about the use of capacitors, it is written in such a way that the capacitor stores electric charge in itself and discharges it when necessary. What we need to know is when should the capacitors be charged and when should they be discharged and how is this possible? Therefore, first…

Diode and its types – diode usage in the circuit

Diode is another electronic component that has two pins. These two pins (bases/legs) are called cathode (negative) and anode (positive). The cathode pin is usually shorter or closer to the white (or black) ring on the body of the diode. The diode is shown on the schematics map with the D letter, and its applications…

Resistor and how to use it in the circuit (basic electronics)

Resistor prevents additional voltage or current from entering the part in the circuit. The maximum allowed voltage or current of each part may be different from another part, if it exceeds, It will cause the overheat and the material of that part combines with oxygen and in the other words, the part burns. The resistor…

Electronic Parts

All parts that have conductive ends/bases/pins and make changes on the input electric current, are called electronic parts. You see many electronic components every day and now you have decided to learn how to work with them. If you have more advanced parts, it means that you have access to higher technology. If you have…

Electronics – Basic concepts in electronics

We know that all materials are made up of a large number of atoms and the atom itself is made up of electrons, neutrons, protons and the fundamental particles. The science of electronics is created from the displacement of several electrons among the atoms of matter. The important work of this science is to express…

8 Channels Infrared Receiver (Code Learner) With Arduino UNO

The IR receivers typically work in 37 KHz frequency. The “8 Channels Infrared Receiver” project receives the IR signal via HS0038A2 (or similar modules), which the module filters the 37 KHz signal and sends the data in 1 Kbps speed to the ArduinoUNO board. The Project’s Download Link: Infrared Receiver Source Code For Arduino UNO…

Over The Air Update

Introduction Of The Over The Air Update (OTA Update) This article discusses about how to update a microcontroller’s program/chip firmware over the air (OTA Update). With increasing the source code lines and the firmware/program size, probability of errors will increase. So the application of OTA update is usually in smart circuits with larger firmware size.…
