ArduPicLab published the details on how to build a current, voltage and power datalogger with Arduino and the INA226 module: In the past I have developed various projects of ammeters based on Hall effect current sensors such as the ACS712, or on High-Side Current-Sense Amplifiers such...

This small constant current LED driver Nano shield has been designed using CAT4104 IC from ON semiconductor. Its 4 channel LED driver. The board has provision to mount 20 SMD 1206 LEDs. The LED can be RED, GREEN, BLUE and WHITE. Reduce the number of LED to 12 if White LEDs are used, as...

Beetle is one of the smallest Arduino Leonardo board.  It derives its core notion from minimalism without compromising functionality. It comes with Atmel AtMega32u4 ( datasheet) @16MHz clock time and has expanded amounts of interfaces: 10 digital pins, 5 analog pins, and 4 pwn pins....

This is an ESP8266 based coronavirus tracking project from "Volkan Unal" on github.com. The tracker can be configured to display the details of your own country. Instructions 1- Change your wifi information from WifiConnect.h file char ssid[32] = "yourssid"; char password[64] =...

Flow rate and volume helps tell the amount of fluid going into, or through a particular vessel. For certain process automation applications, this simple-sounding fluid measurement task is so critical to the success of the project that, failure to get it right, could bring the entire...

David Johnson-Davies published a new project on his personal blog. He shows us how to build a minimal microcontroller on a breadboard based on the ATmega4809, the microprocessor used in the latest AVR-based Arduino boards. It includes a USB-to-serial converter so you can connect it to...

Angelu (Elsofgel), a Canadian-based electrical engineer has developed an Arduino shield to implement an SPI to Ethernet Interface (SEI) on the PIC32 microcontroller. While it seems very similar to the Wiznet’s chips, the major difference being that it is a software implementation and...

One of the best things about being a maker is the ability to make your own tools. We have covered the development of several electronics tools in past, from voltmeters to battery testers. For today’s tutorial, we will add another tool to the list by examining the development of a...
