@Undefined A spurious serial data transmission occurring when your microcontroller (
MCU) resets is kinda common which leads to a garbage character appearing on your serial monitor. it's usually caused by UART Line Behavior During Reset, Baud Rate Instability and electrical noise to resolve this u should use a capacitor on d reset pin to reduce noise and signal instability and also ensure UART transmissions are only enabled after full initialization, Implement pull-up/pull-down resistors on UART lines to prevent them from floating and apply logic to ignore or filter unexpected characters during startup.
