Leds
Led bar 8 RGB WS2812B
Standard analog RGB leds require 4 wires per LED and PWM signals to modulate their intensity, so applications with many of those leds are complicated to implement and require a lot of pins on your MCU, or an additionnal IC.
WS2812B leds are RGB leds that integrate a logic circuit with a serial port/bridge. Their connection is very simple since only 3 wires are needed to drive a group of several dozens of leds connected to each other, each led being independently controllable in color and intensity !

Linear Magnetic Sensor DRV5053RA
This hall effect linear magnetic sensor senses a magnetic field and produces a voltage proportionnal to the field, centered at 1V.
This sensor enables to replace potentiometres for analog commands, avoiding any mechanical wear.
If you have a board that is already programmed for potentiometers, you can replace them with this type of sensor without reprogramming the board (but pay attention to the wiring which is different).
Sensitivity : 47mV/mT / 4.7mV/Gauss
Supply voltage : from 2.7 to 38 Vdc
Data Sheet : https://www.electroseed.fr/docs/DRV5053.pdf
