FREQUENCY RANGE OF ARDUINO 



                                 No we can't change frequency of Arduino to any value but we can change the frequency or Arduino to a desired level. It can be changed for the need of the user or programmer. Usually an Arduino board(no matter which type of board that is  the Arduino mega or Arduino UNO or Arduino NANO or Arduino LEONARDO etc......) works between the frequency range of minimum 31 Hz to maximum 65535 Hz. ESP8266 microcontroller on the other hand handles much more larger frequency ranges than the Arduino and also it has WIFI and Bluetooth facility comes with various models. In the board ESP8266 or ESP32 a user or programmer can change the frequency much higher than the Arduino by changing or moderating some lines of code in the coding or software or debugging section or Arduino IDE or Compiler. 



                        Next the IC 555 timer, it plays a vital role in frequency related circuits though the frequency range can be changed by changing the biasing capacitance of the timer IC 555.  Anyway Arduino is well suited for the projects which works on time or frequency integration even though at low cost.  For Example :  The individually addressable RGB led strips are very much depend upon the time varying frequency signal or input data from the Arduino. Controlling a server motor with an Arduino also works with the varying time interval of different frequency signals of the Arduino. And also controlling a BLDC motor's ESC (Electronic Speed Controller) giving the required time varying signal at different frequency signals of the Arduino.










                            Well Raspberry pi board on the other hand has more specifications than the Arduino but at the same way raspberry was not a proper microcontroller or microprocessor for a time or frequency related circuits or projects, it fails at some situations, it can handle much more larger data than the Arduino due to its high memory and RAM capacity. Arduino does all the time related or frequency dependent projects or circuits at low cost. So, Finally we conclude that the frequency of the Arduino can be changed to a particular level not much more higher.


Hope you guys learnt something New !!!!!
