Isn’t it nice when you can hit two birds with one stone? That’s exactly what we’ve done as we approach both Arduino Day and Saint Patrick’s Day with our version of the Chug-O-Meter! We absolutely loved what the circuit.io team did with their Chug Meter but thought that we could add more to its survivability […]

Presented here is an Arduino based audio meter that uses a liquid crystal display (LCD). A VU meter or standard volume indicator (SVI) is a device that displays a representation of signal level in audio equipment. In this project, the intensity of left-channel and right-channel audio signals provided as input to Arduino UNO board is displayed as

A digital soil moisture meter is used for indicating the water content of a given soil sample. As crop production requires water at different stages and in different amounts, it is important to measure soil moisture from time to time to know its status. The digital soil moisture meter circuit presented here, for monitoring the

Microcontroller based miniscule event counter presented here is based on the inexpensive Digispark Attiny development board. One advantage of this design is that any type of active or passive switch can be connected to its trigger input. Whenever the switch closes event will be counted inside the microcontroller and would be displayed on the 4-digit
