RDA5807 FM DSP radio with weekly schedule which is controlled by XIAO ESP32C3
Feb 02,2024
This FM radio that can listen to radio programs based on a pre-set weekly schedule, has been produced.The RDA5807FP is an FM DSP radio IC made by RDA Micro. It is easy to use because it imprements in an SOP 16-pin package and uses fewer components.It is controlled via an I2C interface of Seeed Studio XIAO ESP32C3, and I use its WiFi functionality to achieve the target functionality.I use NTP to set the Clock and the built-in web server function to set the weekly schedule.This FM radio ...

DIY Precise Arduino Miliohmmeter
Pavleski Jan 26,2024
 In practice, we very often need to measure low resistances. Measuring low-value resistances, especially those less than 1 ohm, is nearly impossible with a standard multimeter. On the other hand, an commercial milliohmmeter instrument is in the price range of several hundred dollars and is not cost effective for self builders.  This time I will describe to you a simple and inexpensive way to make such an instrument, for the production of which we will not need more than a few doll...

Dual ON/OFF controller board for 5V-24V RS-485 sensors and 5V low current signal control
Ulloa Jan 22,2024
Hello,I'm sharing a very simple, yet useful board designed to be used in a Sensor system, with low power requirements (as main system uses Solar Panels) to enable actual ON/OFF of devices that don't need to be always ON, but there is no option in the main controller to turn them OFF.The system has been working with several different types of MODBUS sensors (that's why the RS-485 port) for a couple of years now, controlled by an ATMEGA2560 based custom board.Some Considerations:FQP30N06L MOSFET C...
