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.
Design and assembling of a linear source
You needs a DC generator source, but for some reason, can’t purchase one? You can build your own linear source, in this post is shown how.
Arduino tutorial (Part 13, joystick)
In this tutorial, it is shown how to use joystick module in Arduino to make projects. This module is similar to the model found in Playstation controls.
Multivibrators with 2 transistors: astable, monostable and bistable
A multivibrator is a circuit which has two states in output, high or “1” and low or “0”. The Multivibrators can be of three types: Astable, monostable and bistable. In this…
Theorems of superposition, Thévenin and Norton
In this post are shown theorems of superposition, Thévenin and Norton. Only DC circuits with resistors are used as examples.
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.
