With infrared (IR) sensors, can build a line follower robot. The construction and operation of this type is the post’s subject.
Category: Analog electronics
RC circuit analysis
In this post is shown how to analyze a RC circuit, by that, with resistors and capacitors.
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.
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.
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.
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.
