This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

The gear potentiometers are popularly used in audio systems. They can be easily connected to the analog input of a microcontroller like an Arduino or a Raspberry Pi. Below are the quick technical ...

He’s doing this with a bathroom scale underneath the coffee machine connected to an Arduino Ethernet module. By measuring the weight of the coffee pot and subtracting the known empty weight ...

The outputs from the potentiometers are analog, so they can have a value only between 0 and 1,023 when read by the analog pin of the Arduino. This number sends a pulse to the Arduino, which in ...

think temperature sensors and potentiometers. Outputs, on the other hand, are components that receive data from the Arduino. This includes LEDs, LCD modules, servo motors, and buzzers.

Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...
