How does logic work? Triggers

Nowadays, homemade electronic products on microcontrollers are trendy. I am even more interested in assembling different devices on simple logic circuits. Their operating principle is more visual, which gives me aesthetic pleasure. Today we are going to show you four simple devices. Three of them are based on triggers, and the fourth one, which we will start with, could use a trigger.

DALI is the most widely used digital lighting control protocol

DALI is a digital lighting control protocol using a simple two-wire bus for up to 64 devices. It enables individual/group control, two-way communication, and flexible installation. While popular, it has command delays and requires gateways for smart home use. New versions like DALI-2 and DALI+ expand its capabilities.

How to detect a raindrop?

Resistive moisture sensors use exposed PCB traces. Rain needs AC due to high resistance. A Schmitt‑trigger oscillator, filter, rectifier and integrator produce a logic signal for an LED or actuators.

Analog Remote Lighting Control

The 0-10V and 1-10V analog protocols control light dimming. 0-10V allows full off at 0V, while 1-10V requires a separate power switch. Despite signal loss over distance, their low cost ensures use in modern hybrid systems and streetlight control.

How does a weight sensor work?

A load cell measures weight via strain gauges on a beam; their resistance changes with bending. This creates a small voltage in a Wheatstone bridge, which a specialized chip like the HX711 amplifies and digitizes for a microcontroller.
