Reaction trainer/timer

General overview:This is a reaction trainer that I made for school work. It's a very simple design and requires minimal hardware. There are some required components like:-Bambu lab COB LED strip 200mm-A simple push button (https://www.amazon.co.uk/Gebildet-Prewired-Waterproof-Momentary-Stainless/dp/B08L49F7DV/ref=sr_1_6) I used this one.-An esp32 controller-A mosfet (preferably LB8721)-A couple jumper wires and a 100ohm resistor and a 10k ohm resistor and a breadboardAssembly instruction:1.Wire the electronics using either a small breadboard or a prototype PCB board(either are fine).Button:GPIO13 ─ Button ─ GNDLED and mosfet:GPIO27 ──220Ω── GateGate ──10kΩ── GND5V ─── LED +LED − ─── DrainSource ─── GND2. Upload the code to the ESP32.const int buttonPin = 13;const int ledPin = 27;unsigned long startTime;unsigned long reactionTime;// debouncebool buttonPressed(){ if (digitalRead(buttonPin) == LOW) { delay(20); if (digitalRead(buttonPin) == LOW) return true; } return false;}// flash L
