Guiding Light
This smart plinth lighting automatically switches on and off when you get up at night. The motion sensor sees you get out of bed and the light turns on! There is an illuminated path from bed to toilet. Obstacles on the way to the toilet are immediately visible and tripping hazards are prevented. Scientific research shows that the fear of falling is significantly reduced when using a Guide Light. The LED lighting has a perfect light intensity. The light is subtle enough not to wake you up, but bright enough for a reliable orientation. The Guiding Light is much more than just a night light.

Elektor Digital Home Automation and Electronics for Starters (E-book)
Projects with Arduino, ESPHome, Home Assistant, and Raspberry Pi & Co. We start by learning about electrical engineering by looking at the basics of voltage and current and the types of resistors, diodes and transistors. In the second chapter, we get to know the most famous microcontroller, the Arduino Uno. We will analyze its structure, learn how to code and carry out illustrative examples. In chapter three, we set up Home Assistant on a Raspberry Pi. We look at scenes, automations and the general handling of HA. We then look at the MQTT protocol, which is the gold standard in home electronics communication, so to speak, but other interfaces such as I²C, SPI and UART are also explained in detail in this chapter. In the following chapter we will take a look at the ESP8266, the more modern ESP32 and of course the ESP32-CAM. First some theory, followed by practical examples. Indoor climate sensors for temperature and humidity, motion sensors, RFID readers and many more sensors are explained in detail in chapter 7, followed by practical examples. Chapter 8 deals with actuators such as the 7-segment display, servo motors, displays, stepper motors and much more. You can use ESPHome to integrate sensors and actuators into Home Assistant without any programming effort. In this chapter, you will be guided step by step through how to integrate your own sensors. Do you want to bring more colorful light into your living space? Then the chapter on LEDs is just right for you. The different types of LED lights are explained here and, of course, the basics of lighting technology are not forgotten. There are a lot of ICs in electronics that make our lives easier; in this chapter we get to know a few ICs and the basic knowledge is immediately put into practice. All code examples do not have to be typed out, you can download them for free from GitHub and modify them. The respective link (with QR code) can be found in the code example.

Sequent Microsystems Home Automation V4 8-Layer Stackable HAT for Raspberry Pi
The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485.The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs.A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state. Ideal solution for your Raspberry Pi Home Automation projects. Read temperatures in up to 8 zones with analog inputs. Control your heating and cooling system with the 8 onboard relays. Use the 8 optically isolated digital inputs for your security system. Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup. Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V). Control four light dimmers using 0-10 V outputs. CompatibilityThe card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user.Power RequirementsThe Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on. RelaysThe 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF.Stacking Multiple CardsUp to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level.Features Eight relays with status LEDs and and N.O contacts Eight layer stackable Eight 12-bit A/D inputs, 250 Hz sample rate Four 13-bit DAC outputs (0-10 V dimmers) Four PWM 24 V/4 A open-drain outputs Eight optically isolated digital inputs Contact closure/Event counters up to 500 Hz Four Quadrature Encoder inputs 26 GPIOs from Raspberry Pi available 1-WIRE and RS485 communication ports Pluggable Connectors 26-16 AWG for all ports On-board hardware watchdog On-board resettable fuse Reverse power supply protection Brass stand-offs, screws and nuts included Hardware self-test with loop-back cable Open source hardware, schematics available 32-bit Processor running at 64 MHz Uses only I²C port (address 0x28..0x2f ), all GPIO pins available Specifications Power supply: Pluggable Connector, 5 V/3 A Power consumption: 50 mA (all relays off), 700 mA (all relays on) On board resettable fuse: 3 A Open Drain outputs: maximum 3 A, 24 V Relays 1,2,3,4,5,8: N-O contacts, 6 A/24 VAC or DC Relays 6,7: 3 A/24 VAC or DC Analog Inputs: Maximum input voltage: 3 V Input Impedance: 50 K?

Elektor Digital Home Automation Projects with Arduino (E-BOOK)
Een Arduino-bord is nu 'het' basisonderdeel geworden in de makersgemeenschap. Niet langer is een introductie in de wereld van microcontrollers voorbehouden aan de expert. Als het gaat om het uitbreiden van de mogelijkheden van het basis Arduino-bord, staat de ontwikkelaar er echter nog steeds grotendeels alleen voor. Als je echt innovatieve projecten wilt bouwen is het vaak nodig om tot op componentniveau te komen. Dit kan veel beginners voor grote problemen stellen. Dat is precies waar dit e-book begint.Dit e-book legt uit hoe een grote verscheidenheid aan praktische projecten kan worden gebouwd met behulp van onderdelen die samen met het Arduino-bord in één kit worden geleverd. Deze kit, genaamd de 'RFID Starter Kit for Arduino' (SKU 17240) is niet alleen beperkt tot RFID toepassingen maar bevat meer dan 30 componenten, apparaten en modules die alle gebieden van de moderne elektronica bestrijken.Naast de meer eenvoudige componenten zoals LED's en weerstanden zijn er ook complexe en geavanceerde modules die gebruik maken van de nieuwste technologie zoals: Een vochtigheidssensor Een veelkleurige LED Een grote LED matrix met 64 lichtpunten Een 4-karakter 7-segment LED display Een infrarood afstandsbediening Een complete LC-display module Een servo Een stappenmotor en besturingsmodule Een complete RFID-leesmodule en beveiligingstagDaarnaast bouw je nauwkeurige digitale thermometers, hygrometers, belichtingsmeters en diverse alarmsystemen. Er zijn ook praktische apparaten en toepassingen zoals een volautomatische regensensor, een geluidsgestuurd afstandsbedieningssysteem, een multifunctioneel weerstation en nog veel meer.Alle beschreven projecten kunnen worden gebouwd met de onderdelen die in het Elektor bouwpakket worden meegeleverd.
