ATtiny Schematics
An ATtiny microcontroller (MCU) is a small, low-power integrated circuit designed for use in embedded systems. These MCUs are commonly used in a variety of applications, including control systems, sensors, and data processing. They are known for their low power consumption and high performance, making them an ideal choice for battery-powered devices and other applications where power efficiency is a key concern. One of the key features of ATtiny MCUs is their ability to be programmed with a wide range of firmware, allowing them to be customized for a variety of different tasks. They are also highly versatile, with a range of input/output (I/O) options and support for a variety of communication protocols. Flux.ai has the world's largest community-driven public library of ATtiny MCUs, with a wide range of footprints, symbols, datasheets, and simulation models available. Whether you are designing a new system or looking to upgrade an existing one, Flux.ai's library can provide the resources you need to get started. So, if you are working with ATtiny MCUs, be sure to check out Flux.ai's library for all the latest information and resources.
ATTINY85-20MU
AVR AVR® ATtiny, Functional Safety (FuSa) Microcontroller IC 8-Bit 20MHz 8KB (4K x 16) FLASH 20-QFN-EP (4x4) The ATTINY85-20MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip (formerly Atmel), designed for compact embedded systems that require efficient control, small footprint, and low energy consumption. It runs at up to 20 MHz and is based on the AVR RISC architecture, enabling most instructions to execute in a single clock cycle for fast and efficient processing. This MCU is widely used in space-constrained applications such as IoT nodes, small automation systems, sensors, and consumer electronics due to its balance of performance, peripherals, and ultra-compact QFN package.

Etapa 1: Recolección y Almacenamiento de Energía Entrada: tus cactus en serie (ej. 15 cactus × 0.5 V = 7.5 V). Componente clave: Supercapacitor o batería recargable de baja capacidad (Li-ion o LiFePO4, 3.7V-7.4V). Diodo Schottky entre los cactus y el capacitor para evitar descarga inversa. 🛠 Ejemplo de componentes: Supercapacitor de 5–10 F, 5.5 V o batería de 3.7 V (tipo 18650). Diodo Schottky 1N5819. Módulo cargador TP4056 (si usas batería). Etapa 2: Aumento de Voltaje (Boost Converter) Conversión de 3.7 V / 7.5 V DC a 110 V AC. Necesitas: Boost Converter (DC-DC Step-up) de hasta 300 V DC. Inversor DC-AC (pequeño, tipo mini inverter para LEDs) que convierta ese voltaje a 110 V AC. NOTA: Algunos focos LED pueden funcionar con 110 V DC directamente, si quieres evitar el inversor. Etapa 3: Detección de Noche Sensor LDR (resistor dependiente de luz) conectado a un comparador (ej. LM393) o a un microcontrolador (como un ATtiny o ESP8266 si quieres funciones extra). Al bajar la luz solar: El comparador activa un MOSFET o un relé que conecta la energía almacenada al foco.
