Introduction to servo motors Servo motors are electromechanical devices that are used to achieve precise control over the position, speed, and acceleration of a mechanical system. The control mechanism used by the motor is the pulse width modulation. They are commonly used in robotics, manufacturing machinery, automation equipment, and other sectors and applications that demand … Read more
Introduction to smart door system Security is a serious problem that calls for proactive measures by all stakeholders and owners of residential buildings. Most buildings (residential and companies) do not have adequate security systems that monitor intruders and prevent unauthorized access. To reduce this, this smart door system uses the model of keypad-enabled access and … Read more
Introduction to arduino IDE software Arduino IDE software is an IDE that is used as a coding environment for an arduino board. In a previous post, we focused more on the physical component and how to use the board in a circuit. The arduino IDE software serves as a development environment where all the code … Read more
Introduction to Arduino Arduino is one of the most popular microcontroller ICs for electronic projects. It is an open-source, programmable electronic component. It is made of a physical hardware that can be programmed and a software referred to as Arduino software (which is an IDE) that is installed on a computer to program the physical … Read more
Introduction to automatic security light system An automatic security light system turns on when it senses darkness without anybody having to switch it on. In most houses, we use a manual security light system which has to be turned on manually. The major drawback of this system is that when no one is around to … Read more
Introduction to the operational modes of a 555 timer A 555 timer is one of the most used integrated circuits for most electronic projects. We would discuss in detail all the operational modes of a 555 timer. It functions in different circuits as either a switch, a flip-flop, or an oscillator. A 555 timer can … Read more
Introduction to rain detector alarm system A rain detector alarm system is a simple device that alerts households when it senses rainfall. In areas where rainfalls are common or during rainy seasons, it’s important that we get informed about rainfall on time so we make necessary arrangements before the rain starts falling heavily. The device … Read more
Introduction to diodes We would focus on how diodes work and what role they play in circuit design. Diodes are electronic components that allow current to flow in one direction but not the other. Most common diodes have two leads. Some are clear with reddish-orange on the inside and a black stripe on one end … Read more
Introduction of battery charge controller Since the innovation of secondary cells, the Recharging of batteries has been made possible by passing direct current through them. However, challenges have risen on how to know when the battery is fully charged and to cut off charging automatically if the battery is fully charged since overcharging damages battery … Read more
Introduction to transistors Transistors are active electronic components that can be used for amplification or switching circuits. We would look in detail at how transistors work. We would be focused on BJTs The basic type of transistor is the bipolar junction transistor. Bipolar junction transistors (BJT) Bipolar junction transistor is similar to diodes. Diodes have … Read more
