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...

Game Controller with Arduino Pro Micro
Saber C++ Jan 16,2024
In this tutorial we’re going to make a DIY game controller similar to an Xbox controller for half the price! Check out the video or scroll past it for the written tutorial!First, let’s gather all of the materials we’ll need for this project:The Arduino Pro Micro, which is the smallest Arduino board that has the 32u4 USB chip, which we need to communicate with the computer as a controller.The Custom Controller PCB, which will hold all of our components together (and looks awesome!).2 Joysticks, I...

Colloidal Silver Generator
PUEYO MUÑOZ Jan 15,2024
Construction of a Colloidal Silver generator with Arduino. The generator is programmed to produce 200mL of colloidal silver, with concentrations to choose between 10 and 100 ppm. Colloidal silver is composed of high-purity silver nanoparticles, which remain suspended in purified water. Silver nanoparticles measure between 5 and 100nm, and have a positive electrical charge due to the electrolysis process used in their production. Colloidal silver could be considered a homemade antibiotic, perhaps...
