From time to time, I see people trying to build an audio VU meter. In the analog era, that’s typically done with a voltage divider + a series of comparators; or using chips like LM3914/3915. Those chips are harder and harder to find, or you may need more resolution, or a different output profile. What […]

In recent weeks a number of ESP8266 devices have become available offering more than the previous defacto maximum of 4MB of flash memory. Wemos’s D1 mini pro offers 16MB of flash, and the ESP-100 claims to offer 8MB. To put this in context, the original ESP8266 modules (such as the ESP-01) offered 512KB of flash,

From the minds at http://arduinotronics.blogspot.com/ Important Update! Since so many people were having problems with the INA125P, we now have a new and improved version that uses the Hx711 24bit ADC amplifier module. http://arduinotronics.blogspot.com/2015/06/arduino-hx711-digital-scale.html My goal was to create a programmable scale for weighing objects, parts counting, even directing product flow on a conveyor system.
