Arduino tutorial (Part 10, real time clock)
This is part 10 of the Arduino tutorial series, which will be shown the operation of a real-time clock and a project example.
Gauss accelerator
The Gauss accelerator is a linear magnetic accelerator which launches metal spheres to considerable speeds. In this post, will be shown the operation and this experiment’s construction.
Voltage multiplier circuits
In this post will be shown how it is possible to produce high voltages only with diodes and capacitors. These circuits are the voltage multipliers.
Basic concepts of alternate current (AC)
Meeting requests, the subject is about basic concepts of AC. Has been already mentioned AC in the post about electromagnetism, this post will go deeper.
Circuit analysis (Part 2)
In this second part, will be presented two circuit analysis methods. Will be shown only DC circuits with resistors.
Arduino tutorial (Part 9, music and 4×4 keypad)
This post is the part 9 of Arduino tutorial. Will be shown how to play music using a buzzer or a speaker and how to use a matrix keypad 4×4.
Meet the electromechanical relay
In this post will be shown an electromechanical component called relay. Will be shown how it works and some project examples.
Circuit analysis (Part 1)
This is a basic concepts post destined to students and beginners in the area. This is the first part about how to make circuit analysis in direct current only with resistors.
How to polarize the BJT transistor? (Part 1)
Polarization is important to design circuits with transistors. In this post, will be shown how to polarize the BJT transistor in CC mode.
