The common base is little known configuration for amplifiers using BJT. This type is used in high frequencies.
In this post, it is shown another type of amplifier configuration using BJT. This time, it is the common collector or emitter follower.
In this post, it is shown how to design a BJT amplifier with voltage divider on common emitter mode. Two examples of projects are presented.
In this post are shown 2 digital electronics projects, using DIP integrated circuits: luminous effect with 74HC595 and a semaphore.
This is the post’s second edition. Additional information has been added.
The MPU6050 module is an accelerometer and gyroscope with 6 axis degrees of freedom. In this post, are shown the operation and a project example.
In this post, are shown 2 circuit projects: an AC voltage detector and a cooler with LED effect.
In this post, are shown how to use Arduino with the TM1637 module, a 7-segment display with 4 digits and 3 project examples.
The current sources are electronic circuits that provide a constant current. In this post, are shown some examples.
This is the post’s second edition. It’s shown one more project to control servomotors with a joystick, using another method.
