Servomechanisms are devices necessary for the construction of DIY electronic projects characterized by a greater degree of expansion. However, it is worth paying attention to the fact that the servos are not equal to each other. This means that we can distinguish many types.

In this category, we invite you to order and to familiarize yourself with great micro servos. The offer of micro-type servos applies to devices whose working range oscillates from 120 ° to 360 °. But how the micro-servos really work?
Micro servos work on exactly the same principle as their larger counterparts - using the same external hardware and software as for standard and mega servos, you can also control smaller micro servos. Micro servos are a very good solution for people starting their adventure with embedded systems or robotics. Familiarize yourself with the entire offer of the Botland online store, because we also have servo drivers for sale compatible with Arduino and Raspberry Pi as well as programmable electronics from many other well-known manufacturers!
What are servos and how do they work?
Servomechanisms are, in a simple way, a closed control system that uses the feedback phenomenon. These can be automation systems, regulation systems. Within the feedback phenomenon, the input signal is always some stimuli (data) such as position, velocity or acceleration. Oftentimes it's just a shift. Servomechanisms have been popular in industry for many years as they are used to build most industrial robots. Various types of servo mechanisms are also often used in the Arduino environment and are found in every robot based on an Arduino board, but not only. They are also popular in PCBs from Raspberry Pi, DFRobot and many other manufacturers. Using the servo, we can do some really practical projects - a mechanical arm, a leg, and other components responsible for the movement of a given automatic fragment. This is why it is difficult to imagine constructing any robot in a situation where we are not equipped with any servo-motor compatible with it!
Rotational speed and other important parameters of servo operations
There are many different parameters that must be considered when choosing the perfect servo for your project. These parameters include, first of all: geometric dimensions, own weight, operating range, supply voltage and control method. As in the larger counterparts, the final effect is determined by the torque and rotational speed of the servo. It is worth knowing that the torque describes how much mass the servo can move through the arm of a certain length. This arm is usually a pusher hooked with one end to the servo horn and the other end to the servo-controlled object.
In turn, when it comes to the rotational speed of the servo, it is usually parameterized as the time needed to rotate the axis with the dragline by an angle of 60 °. This is a standard adopted by all manufacturers. Anyway, before buying, be sure to check the specifications of a specific servo and make sure its technical parameters.
If you are a beginner in robotics and automation, and therefore need a servo to control the height of a small RC airplane with a wingspan of less than 1 m, then the optimal use of a servo with a rotational speed of 0.17 s / 60 ° will be optimal. In contrast, to control the tail rotor of a RC helicopter, a servo with a rotational speed of 0.05 sec / 60 ° will be required to rapidly counteract the main rotor torque.
Using servo mechanisms for Arduino programmable electronics
The process of controlling the servo directly from the Arduino boards is very simple to use. To make the task even easier, it is worth connecting the servo or microservo to the Arduino via a dedicated shield. This is due to the fact that the current efficiency of the GPIO outputs in Arduino may turn out to be insufficient in relation to the hardware requirements of the servo (the maximum operating current from a single Arduino output is 40 mA).
Servos and micro-servos, the current consumption of which does not exceed the current capacity of the Arduino outputs, can be connected directly. In this case, the black servo lead should be connected to the ground lead (GND), the red lead to the supply voltage (+5 V), and the yellow lead to one of the pins giving a binary signal at the output. You can also connect the red wire to the pin set as a digital output, which will be logically high. In turn, you must set the black wire to the digital output to the logical low state.
It is worth remembering that when using a given servo, the power consumption of which exceeds the energy capacity of the Arduino, then you should use an external battery or power supply. Actually, for proper and safe operation, remember that the ground pole of the external voltage source should be connected to the ground lead (GND) on the Arduino.
Yet another method of controlling the servos is to simply load the dedicated "servo library" into the program code in the Arduino compiler. This library enables comprehensive control of servos. It is worth noting that now you can choose from different versions of these software libraries. If you want to control a large number of servos, then it is best to use an external controller and an independent power supply with an output voltage in the range of 4.8 V to 6.0 V.
