Shift register
The shift register is useful for increase the number of the microcontroller’s output terminals and to convert parallel binary data in serial and vice-versa.
Star and delta configurations
In addition to parallel and series, impedances also can make star and delta connections. Also are shown the transformations.
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.
Meet the integrated circuit 4017
In this post, it’s shown the operation of integrated circuit 4017, from CMOS family. In addition to some projects which are possible to make with this chip.
Capacitance and inductance: More information
I received requests to write more about capacitance and inductance. This post can be considered as the second part of derivated electrical quantities.
PCA9685: How to use with Arduino?
In this post, it’s shown how to use the PCA9685 module with Arduino. To control many servomotors this is a better solution than traditional commands.
How to polarize BJT transistor? (Part 2)
This is the second part about BJT polarization. Are shown projects of circuits with fixed and emitter’s stable polarization.
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.
