Multivibrators with 2 transistors: astable, monostable and bistable
A multivibrator is a circuit that has two states in output, high or “1” and low or “0”. Multivibrators can be of three types: Astable, monostable, and bistable. This post shows…
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.
Infrared sensors
This post’s subject is infrared sensors. It is possible to build or buy a complete one and make many electronic and robotic projects.
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.
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.
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.
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.
Meet the zener diode
The zener diode is a special type of diode. In this post, will be shown how it works and some ideas for projects.
