Fruit and vegetable market is a big sector that is worth more than 200 billion euros worldwide, this is expected to grow even more in the next decade due to an increasing healthier lifestyle across different European countries. When fruits and vegetables are sold at the supermarket they are usually exposed in open spaces, anyone […]

Hello there! I hope you all are fine and in good health. This instructable is about making your own current sensor that is compatible with Arduino and most other widely popular microcontrollers. This project features a compact design and an all SMD component based circuit, making this sensor module very compact for it’s range. This […]

So this is my microbot V1 which is an ESP32 based robot which is powered by a Wemos d32 pro and controlled by Blynk. Its body is a 3D printed square surface that has mounting holes for the same size PCB which is mounted with this setup in the sandwich config to hold the battery […]

This is add-on of the audio amplifier project result which is introduced in other instructable. (https://www.instructables.com/PC-Speaker-Amplifier/) Usually many types of sound level meters are directly connected with input (or rarely output) signal lines of amplifier. But personally I’m thinking any electrical connections with amplifier circuit may surely degrade music playback quality by inserting some noises […]
This project was conceived of after I examined the types and styles of various off-the-shelf Metronomes. I am currently learning to play the piano and having a Metronome in order to keep time was necessary. I felt sure that I could build one based on a standard Arduino Uno R3 board. The resultant Metronome has […]
