Hi Redge, You can build a delay timer circuit to protect your fridge. Here’s a basic outline: 1. **Power Relay**: Use a relay rated for 240V AC and at least 10A (to handle the fridge's startup current). 2. **Delay Timer**: Use an off-delay timer module, adjustable up to 10 minutes. 3. **Wiring**: - **AC IN to Timer**: Connect the AC input to the timer's power input. - **Timer to Relay**: Connect the timer's output to the relay's control input. - **Relay to Fridge**: Connect the relay's switch terminals between the AC input and the fridge. **Operation**: - When AC IN is turned off, the timer starts the delay. - The relay will only activate and supply power to the fridge after the 10-minute delay, even if AC IN is switched back on immediately. Ensure all components are rated for 240V and handle the required power safely. If unsure, consult an electrician for assistance.

You say: " one wanted the current to rise lowly from 5 volts to 10 volts each ten seconds," Is 5 volts off for the lamp? Also you all say: "had its light intensity decreasing to zero volts:" That statement is confusing; which is going to zero the light intensity or the applied voltage?

In this blog, I will show you how to integrate an ultra-sonic sensor with ESPHome in home assistant. An ultra sonic sensor is a device that can measure the distance to an object by sending and receiving sound waves. It can be used for various applications, such as obstacle detection, level measurement, parking sensors, etc. What is ESPHome and Home Assistant? ESPHome is a system that allows you to easily create and manage custom firmware for ESP8266 and ESP32 devices. It uses a simple configuration file that defines the components and sensors you want to use and generates the code and binary files for you. You can then upload the firmware to your device using a USB cable or over-the-air (OTA) updates. Home Assistant is an open-source platform that allows you to control and automate your smart home devices. It supports hundreds of integrations with different services and devices, such as lights, switches, sensors, cameras, media players, etc. You can access and control your home assistant from a web browser, a mobile app, or a voice assistant. ESPHome and Home Assistant work very well together, as they can communicate with each other using the native API. This means that you can easily add your ESPHome devices to your home assistant without any extra configuration or coding. You can also use home assistant to monitor and control your ESPHome devices, and create automations based on their states and events. How to Integrate Ultra Sonic Sensor with ESPHome in Home Assistant To integrate an ultra-sonic sensor with ESPHome in home assistant, you will need the following: An ESP8266 or ESP32 device, such as NodeMCU, Wemos D1 Mini, or Xiao ESP32 S3 Sense An ultra sonic sensor, such as HC-SR04 A breadboard and some jumper wires A computer with ESPHome and Home Assistant installed.

Taking the FETMX6ULL-C platform as an example, if you want to use VPN, you need to open the tun configuration in the kernel in the following way: Kernel Compilation Choose either of the two methods below: 1. Modify the.config file directly Locate the.config file in the kernel source path. Find the CONFIG _ TUN in the file and modify it as follows: Replace the kernel's config file with .config. * Subject to actual use. Recompile the kernel. 2. Configure the TUN using the graphical configuration interface Make menuconfig. Locate the following locations: Save and exit after modification, which can be seen in.config Replace the kernel's config file with .config. * Subject to actual use. Recompile the kernel. Update kernel: The arch/arm/boot/zImage file is generated after compilation, and the kernel can be replaced either by updating the kernel separately or by re-burning it. Use this file to replace the file with the same name in the target path of the flashing tool. Refer to the single-step kernel update chapter of the FETmx6ull-c User's Manual to replace the zImage file separately. Compilation module: In the kernel source code, some of the drivers are compiled in the form of modules, which are loaded from the specified path by the kernel version number when the system boots. When we recompile the kernel and update the kernel, the kernel version number in the system will be changed, the kernel version number can be viewed through the uname -r command. When you update the kernel, the uname -r version number changes, but the version number in the path where the module is stored (/lib/modules/) does not change. It may cause the module to fail to load, typically after updating the kernel, WiFi cannot be used. As seen below, the name under uanme -r and the name under /lib/modules/ are not the same, so you can't load the module when you go to the/lib/modules/$(uname -r) directory when booting up, and you need to change both names to be the same. You can solve this problem in two ways: 1. Modify the module load path and change to the version number of the kernel; 2. Repackage modules; The first method has two disadvantages: a. Not suitable for batch modification; b. Not suitable for changing the module driver; So it is possible to repackage the module when compiling the kernel: After executing the above operation, .tmp/root/modules.tar.bz2 will be generated, which can replace the file with the same name under the target path in the flashing tool. It is also extracted directly in the file system:

W25Q32 refers to a specific model of serial flash memory produced by Winbond Electronics Corporation. In particular, the "W25Q32" is part of the W25Q series, which consists of a range of flash memory chips differing in capacity and features. Standard SPI Instructions: The W25Q32JV is accessed through an SPI-compatible bus consisting of four signals: Serial Clock (CLK), Chip Select (/CS), Serial Data Input (DI), and Serial Data Output (DO). Standard SPI instructions use the DI input pin to serially write instructions, addresses, or data to the device on the rising edge of CLK. The DO output pin reads data or status from the device on the falling edge of CLK. SPI bus operation Mode 0 (0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and Mode 3 concerns the normal state of the CLK signal when the SPI bus master is on standby and data is not being transferred to the Serial Flash. For Mode 0, the CLK signal is typically low on the falling and rising edges of /CS. For Mode 3, the CLK signal is usually high on the falling and rising edges of /CS. Dual SPI Instructions: The W25Q32JV supports Dual SPI operation when using instructions such as "Fast Read Dual Output (3Bh)" and "Fast Read Dual I/O (BBh)". These instructions allow data to be transferred to or from the device at two to three times the rate of ordinary Serial Flash devices. The Dual SPI Read instructions are ideal for quickly downloading code to RAM upon power-up (code-shadowing) or for executing non-speed-critical code directly from the SPI bus (XIP). When using Dual SPI instructions, the DI and DO pins become bidirectional I/O pins: IO0 and IO1.

I ordered a LYG55T024FS52S motor (https://www.hurst-motors.com/lyg55geared.html), but I misread the information about the capacitor. I thought it said capacitor was supplied with the motor, but that was only for the 115 VAC motors. Since I ordered the 24V, mine did not come with a capacitor. So I’m looking to buy one. The spec sheet says I need a 20/15 mfd 50/60 Hz capacitor. This is the closest I’ve found: http://www.mcmaster.com/7245K721/ Will that work for this purpose?
