Arduino tutorial (Part 5, H bridge shields), 2nd edition
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.
Rotary encoder: how it works and how to use it?
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.
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.
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.
Design and assembling of a linear source
You need a DC generator source, but for some reason, can’t purchase one? You can build your linear source, in this post is shown how.
Multivibrators with 2 transistors: astable, monostable and bistable
A multivibrator is a circuit that has two states in output, high or “1” and low or “0”. Multivibrators can be of three types: Astable, monostable, and bistable. This post shows…
