The duty cycle is very important for an application like this LED flasher circuit. The duty cycle we choose determines how long the LED will stay on for compared to how long it is off for. Again, as an example, if we set our duty cycle to be 20%, this means the LED will flash on...
pin 4 and 9, to ground. We don't just connect the 5V to ground. We connect 2 capacitors in parallel to ground. This includes a 100nF capacitor and a 10μF capacitor. This helps filter out noise from the power supply and to make sure the power supply is steady. ...

Installing Balena Etcher on Ubuntu viaaptoffers a straightforward method for setting up this tool to create bootable media. Unlike using the AppImage, installing viaaptensures Balena Etcher is integrated into your system and easily accessible from the terminal. The following text walks you through eac...
When selecting a board in Firmware Flasher, you may see duplicated flight controller boards, with one of them having “Legacy” at the end of the name. It’s usually best to ignore those legacy boards, and choose non-legacy targets, which are newer and have a unified structure. “Legacy”...
Knowing how to update ExpressLRS receivers via FTDI is highly useful, particularly when other approaches fail. This tutorial aims to provide a clear, step-by-step guide to efficiently recover and upgrade your ELRS RX using an FTDI programmer, such as the Radiomaster USB UART Flasher. This proces...
they feel like they’re built for you, and they’re molding to your feet over time. I love everything about them. So, if I needed firefighter boots, logger boots, construction worker boots, or something like that, I would love these even more because they would make my feet feel a ...
If you do not want too high-frequency output. How to reduce it. Suppose that, in the gate circuit, there is something that makes the long delay time up. It will make the frequencies certainly lower. We connected a little capacitor across the inverter as figure above. ...
Next, you just have to insert the LED from one side of the tube and the LDR from the other side of the tube until they are both face-to-face at touching distance inside the tube. After this, confirm whether the assembly is working correctly or not. To do this, take an ohm meter ...
After the firmware is flashed, go to theESPHomedashboard in Home Assistant and check thegas-leakagedevice. It should showONLINE. You may also download and use theESPHome Flashertool to flash thegas-leakage-factory.binfirmware file to your NodeMCU or D1 Mini board. ...
