How to polarize BJT transistor? (Part 3)
This is the third and last part of the series about BJT transistor polarization. Other circuit configurations are shown.
Unboxing of a robotic arm
This is a kit of 6 DOF robotic arm with aluminum pieces to assemble. It doesn’t come with servomotors neither instruction manual.
Hall effect: Operation and sensor
Today are shown how Hall effect works, a magnetic sensor using this phenomena and how o use it in projects with Arduino.
Design and assembling of a linear source
You needs a DC generator source, but for some reason, can’t purchase one? You can build your own linear source, in this post is shown how.
Theorems of superposition, Thévenin and Norton
In this post are shown theorems of superposition, Thévenin and Norton. Only DC circuits with resistors are used as examples.
Arduino tutorial (Part 11, stepper motors)
In this tutorial, it is shown how to control stepper motors with Arduino. In addition to a example of project.
Assembling a line follower robot
With infrared (IR) sensors, can build a line follower robot. The construction and operation of this type is the post’s subject.
Arduino tutorial (Part 10, real time clock)
This is the part 10 of Arduino tutorial series, will be shown the operation of a real time clock and an example of project.
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.
