This project is to build a cheap system to assist athletes with pacing. I intend to use an LED strip around the track and the lights will show the athlete the pace. Like the light will run, like a wave. So it needs to be possible to adjust the speed. Let’s say the athlete needs to complete the lap in 90 seconds. So the light will go around the track (after triggered) at that speed and the athlete just needs to follow the lights.

Circuit #1) The goal is to have a circuit to give/cut power (+3.3v / +5v) to sub ICs/sensors, command by a microcontroller pin. Must cut the input voltage (circuit must be placed between VCC and IC) = high-side switch. Circuit #2) The goal is to have a circuit to enable/cut I2C bus (+3.3v / +5v), command by a microcontroller pin. We want +3.3v and +5v sensors to be connected on the same I2C bus - what about pull-up resistor ? Remarks: If power is cut (by circuit #1), power must not leak through I2C pull-up resistors. Maybe circuit #2 is not necessary if we can be sure that no current leak through pull-up resistors when cut the power.
