In this project I will show you how I combined an Arduino, an INA219 power monitor IC, an OLED LCD and a Micro SD Card PCB in order to create a power meter/logger that has more functions tha... Read more
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.... Read more
First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some ol... Read more
The TSL235 is a light-to-frequency converter. This library reads TSL235 output frequency and convert it to irradiance, and then to illuminance. Irradiance is the power of electromagnetic rad... Read more
This project is a dust detector that use the GP2Y1010AU0F sensor. Attached you can also find the GP2Y1010AU0F sensor library for AVR Atmega.GP2Y1010AU0F is a dust sensor by optical sensing s... Read more
Summary One of the most commonly used medical instruments nowadays is the thermometer. The thermometer is used to monitor or measure the body temperature of a sick person. The idea of creati... Read more
A non invasive current sensor is connected to the spark core (with a few components), and clamped around a cable in the Mains distribution unit. No wiring is required, however Do not try thi... Read more
