Subject: Module to drive leds

south africa
Hi everyone
I'm building my own seed detection system for my drill.
I will be using a timer delay relay module with a trigger function( I attached a picture )
My question is , if a relay aren't a bit of a overkill to drive only leds and a 5v buzzer with?
Do anyone know of a module with similar functions, but something smaller to switch leds on and off?
