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 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 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
Introduction to operational amplifiers An operational amplifier also referred to as an op amp is a high gain DC voltage amplifier, meaning it can use a very small voltage difference between its input to control a much larger voltage at its output usually 100 thousands of times larger. operational amplifiers come in different package types … Read more
Introduction to water level Alarm system Most households with overhead tanks tend to have a problem with overrunning water while pumping water into the tanks. This is a result of not knowing the quantity of water present in the tank and the whole process has to be followed manually. The person charged with the duty … Read more
Introduction of 555 Timer IC 555 timer Ic also referred to as NE555 is an eight (8) pin Ic that is used for switching circuits. They act as timers, oscillators, or flip-flops. The eight (8) pins on the 555 timer ic are as follows; Block diagram of the 555 timer IC The 555 timer ic … Read more
