Grove - sensors and potentiometers

Encoders - Grove series - How do they work?

Encoders are special converters that generate pulses corresponding to a rotary motion. There are many types of this type of device. They are commonly used in more advanced electronic projects. They are used to control various operating parameters in devices such as plotters, automatic welding machines, stationary robots, audio sets and other devices. The basic type of encoder is a rotary encoder - a sensor that passes on a feedback signal. The change of position is not continuous (this is how ordinary potentiometers work), but in a stepwise manner. The basis of the operation of each encoder is the use of the rotational movement of the shaft with a disc with notches. Due to this movement, an electrical signal is created in the form of pulses. The pulses are then counted by a hardware or software counter and processed on this basis to obtain a change in the position or speed of the controlled object. Without encoders, the effective operation of CNC machines and many others would not be possible. In this category you will find the best Grove encoders that are compatible with boards from different manufacturers.

Potentiometers - Grove series - parameters under control

Potentiometers are types of resistors that can be manually adjusted for resistance and other parameters. Potentiometers can be found in a car or in audio equipment - these are popular knobs that are used to change the volume or other parameters. But potentiometers are also used in much more advanced analog-to-digital signal processing applications. They can be connected to various supervisory systems. Depending on the system, you can use them to control the brightness of the LED lighting or the rotation speed of the electric motor. Grove potentiometers, which you will find in this category, are compatible with PCBs from other manufacturers, so you can be sure of trouble-free and fast operation. Connect the selected single rotary potentiometer to the Arduino so that its two extreme pins are connected to the power supply pin (3.3V or 5.0V) and to the power supply ground (GND), respectively. The middle pin must be connected to one of the analog inputs of the analog-to-digital converter. Then it is enough to read the voltage from the analog pin. In Arduino, you can do this by typing the analogRead () command with 10-bit resolution for the Arduino Uno board. Potentiometers will be useful in practically any project in which the user has to decide on individual parameters (e.g. sound volume).
