How to use Neopixel ring with arduino | Control using flex sensor - tinkercad simulation
Ws2812 chip-operated neopixel rings are fun things to be integrated with many Arduino projects. In this video, I will show, how we can control a neopixel 12 led ring with the changing value of a flex sensor.
The output of a flex sensor changes when the degree of bend is changed. It is an analog sensor and its value will be read by the Arduino analog pin. Later, we will use the Arduino map function to map the value of the flex sensor to the ws2812 neopixel ring.
The minimum and maximum value of the flex sensor read by Arduino is 56 and 256. How many LEDs of the ring will be turned on will have a proportional relationship with the flex sensor value.
