This is the second edition of the post about H bridge shields. It has additional information about the use of PWM on H bridge shield L298N.
The rotary encoder looks like a potentiometer, but the operation is completely different. How it works and how to use it in Arduino are today’s subjects.
The Seebeck and Peltier effects are thermoelectric phenomena that explain the operation of thermocouples, temperature sensors with 2 different materials.
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.
In addition to parallel and series, impedances also can make star and delta connections. Also are shown the transformations.
This is the third and last part of the series about BJT transistor polarization. Other circuit configurations are shown.
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.
I received requests to write more about capacitance and inductance. This post can be considered as the second part of derivated electrical quantities.
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.
This is the second part about BJT polarization. Are shown projects of circuits with fixed and emitter’s stable polarization.
