Hourglass ESP8266 Code
Pavleski Feb 06,2025
 A hourglass, also known as an sand clock, is a device used to measure the passage of time. It consists of two glass bulbs connected by a narrow neck, through which sand flows from the upper bulb to the lower one.  The flow of sand is controlled so that it takes a set amount of time to completely empty the upper bulb. Hourglasses are often used as time management tools and decorative items. This time I will present you a very simple way to make a digital version of such a clock. T...

Line Follower Robot using Arduino
Jain Feb 05,2025
A Line Follower Robot (LFR) is an autonomous robot that follows a predefined path, typically a black line on a white surface or vice versa. This guide will walk you through building and programming an Arduino-powered Line Follower Robot from scratch.How a Line Follower Robot WorksThe robot detects and follows a line using IR sensors. Black surfaces absorb most light, while white surfaces reflect it. The IR sensors, consisting of an IR emitter (LED) and an IR receiver (photodiode), use this princ...

Waveshape Monitor Module for Eurorack Synthesizers
Guidolin Feb 04,2025
ReadMe First!!This module is made of two PCBs: a main board and a front board. Both are in the need to realize this module!!PCBWay shared projects form allows for only one gerber to be uploaded. Check this article attachments under "Schematic and Layout" for the front board gerber files and order it too.IntroductionWaveshape monitors have been more and more common in commercial synthesizers. These can be placed at the end of the audio path to visualize the effect on the whole chain (think in exa...

Tug of War Arduino Game on WS2812 Led strip
Pavleski Jan 30,2025
 A Tug of War is a classic team-based game where two opposing teams compete to pull a rope in opposite directions. The objective is to pull the other team across a certain marker (often a line or flag) positioned in the center of the rope. This time I will describe how to make an Arduino version of this game for two players. In fact, each player represents a team and has its own color. Thanks to the LED strip with programmable RGB LEDs with a built-in WS 2812 chip we can make this game...

Clap Switch With PICO 2 and MAX9814
Arnov sharma Jan 29,2025
The idea here was to create a simple breadboard setup for testing with the MAX9814 microphone module and PICO. Setting up this breadboard version was critical in developing a Clap Switch Circuit, which will be developed soon.In this article, we will explore the MAX9814 microphone sensor's setup guide and the preparation of a basic clap switch with it, utilizing an OLED screen and the PICO 2.The idea here was to create a simple breadboard setup for testing with the MAX9814 microphone module and P...

ATTiny1614 and VCNL4200 LED Controller
M Jan 27,2025
This project centers on creating a smart lighting system that dynamically turn ON and OFF an addressable WS2812B LED strip based on ambient light intensity and proximity sensing. The system uses an ATtiny1614 microcontroller as the core, interfacing with a VCNL4200 sensor to monitor environmental conditions.The VCNL4200 combines ambient light and proximity sensing in a compact module, providing real-time data. The ambient light sensor (ALS) measures the surrounding brightness, while the proximit...
