Environmental exposure risk measuring device based on ESP32, ultraviolet light (UV) and CO2 gas sensor modules. It has a voltage booster based on MT3608 chip and a solar panel lithium battery charger with MPPT based on CN3791 chip.

Arduino Uno shield used to monitor chimney smoke and provide feedback to stove. This shield powers the Arduino using TEGs and a battery. This shield provides power to an LED, fans, and a light sensor used to detect light intensity.

This is a project with an animation of LED lights on a board created in flux!! #led #js #flux #stm

First in the world hands-free Otherside communication device! You need only the board, spirit or ghost don't need to move the ouija anymore. Symbols will light up from the inside so you will be able to read your messages and spirit or ghost just need to turn on a red bottom entry LED. Two MEMS microphones allow your interlocutor to clearly hear your questions. WiFi connectivity gives you an opportunity to "dial" without a Medium anytime anywhere. And it has Bluetooth as well, because: "Everything is better with Bluetooth"! This board is powered by a single 10440(AAA) LiFePO4 battery that gives you up to 2 hours of seance.

quiero que de las siguientes instrucciones lo plasmes en un protoboard: Transformador: Convierte la tensión de CA de la red eléctrica (120 V) en una tensión de CA de menor voltaje (por ejemplo, 12 V). Puente rectificador: Convierte la tensión de CA de bajo voltaje en una tensión de CC pulsante. Filtro: Compuesto por condensadores y resistencias, elimina la ondulación de la tensión de CC pulsante y produce una tensión de CC más estable. Circuito regulador: Mantiene la tensión de CC a un nivel constante, incluso si la tensión de entrada o la carga varían. Este circuito puede ser un circuito integrado (CI) regulador de voltaje o un circuito discreto con transistores. Carga: Dispositivo que consume la energía eléctrica proporcionada por la fuente de alimentación, como una bombilla, un motor o un circuito electrónico. Conexiones: La entrada de CA se conecta al transformador. La salida de CA del transformador se conecta al puente rectificador. La salida de CC del puente rectificador se conecta al filtro. La salida de CC del filtro se conecta al circuito regulador. La salida de CC del circuito regulador se conecta a la carga.

Have you ever wanted to wake up to one of the most energizing scents? Have you ever wanted that cup of energy in your hands before you even slide out of your covers? Well want no further! Introducing the Coffee Waker; The knight of your nightstand, a coffee maker alarm clock with one soul purpose, to quickly and scrumptiously wake you up. This is the Coffee Waker Main board. It contains an ESP32-S3, 16 bit Load Cell ADC, 16 bit MP3 DAC, 120V heater cartridge relay, and 12C wakeup light convector.

This project is a Gesture Light Switch Relay Reference Design. It involves an STM32 microcontroller (STMicroelectronics) that interacts with an APDS-9960 sensor (Broadcom) to detect hand gestures. The gesture data is used to control a Toshiba TLP175A relay and an Everlight tri-color LED to switch the light and change colors, respectively. Power is supplied by a Diodes Incorporated's AP2112K-3.3TRG1 regulator. #referenceDesign #edge-computing #edgeComputing #stm #relay #sensors #reference-design

NodeMCU V3 ESP8266 ESP-12E is WiFi development board that helps you to prototype your IoT product with few Lua script lines, or through Arduino IDE. The board is based on ESP8266 ESP-12E variant, unlike other ESP-12E, you won’t need to buy a separate breakout board, usb to serial adapter, or even solder it to a PCB to get started, you will only need a usb cable (Micro USB).
