For loop will do the job if the pins are in series: for (int i = 2; i <= 9; i++) { pinMode(i, OUTPUT); } If pins are random, use an array l...
@jignesh You can use an array: int buttons[]={2,4,5,8,10,13,}; for(int i:buttons){ pinMode(i, OUTPUT); }
Hey everyone, Let's look at some of the advantages and disadvantages of the Raspberry Pi Pico 2 that one should consider before arriving at any conc...
If you are entirely new to microcontrollers and programming, the Arduino Uno might be the better choice due to its simplicity, robust community suppor...
@Deboojit Yes, it's just a sensor. It has nothing to do with the distance calculation.
Yes, you can hook these pins to the PWM pin on Arduino. The Enable pin on the L298N acts as a gatekeeper for the power supplied to the motor. When the...
The microcontroller uses a timer to generate the PWM signal. The timer counts up from 0 to a maximum value. When it reaches the maximum, it resets to ...
@TechSpark No particular spec as far as I know. But the cap value, anywhere between 0.1 µF to 0.47 µF should work
Major differences between ATmega328 and ATmega328P 1. The "P" in ATmega328P stands for "PicoPower," which indicates that this version of the ATmega3...
@Yvette Inside a standard servo motor, there's a potentiometer connected to the output shaft. This potentiometer provides feedback to the control circ...
Hey, Note: UNO R3 supports 8-bit PWM resolution, not 10. Higher resolution means the PWM output can be more finely tuned, resulting in a smoother...
Nano is a very popular dev board and keeping the "Nano" name might be a strategic decision for brand recognition. Even though some Nanos differ sign...
The Arduino Nano has a ceramic resonator instead of a crystal oscillator for doing the same job. Ceramic resonators are also capable of generating clo...
The presence of capacitors is all about dealing with electrical noise and interference. 1) When you spin a DC motor, it actually tries to fight back...
So, analogWrite() is indeed used to create a PWM signal, which can dim LEDs, control motor speed, etc. The name is a bit misleading because it sounds ...
