Arduino Heartbeat Monitor with HW-487 Pulse Sensor and 16×2 I²C LCD
Kuběna Sep 25,2025
This project is an Arduino Uno–based heartbeat monitor that uses the HW-487 pulse sensor to measure and display heartbeats in real time. The sensor detects the pulse through its digital output, and the Arduino calculates and displays the beats per minute (BPM) on a 16×2 I²C LCD screen.Features:HW-487 pulse sensor for heartbeat detection.Real-time BPM display on a 16×2 I²C LCD.Built with Arduino Uno R3 for simplicity and reliability.Compact design, easy to replicate and modify.Great for education...

High Voltage AC/DC to Isolated ADC Signal Conversion Module
Nie Sep 24,2025
High Voltage to Isolated ADC Signal Conversion Module1. Principle: Interfacing a Differential-Output (Isolated) Amplifier to a Single-Ended Input ADCThis project follows the principle introduced in the TI application note:[Interfacing a Differential-Output (Isolated) Amp to a Single-Ended Input ADC (TI SBAA229B)]The AMC1301 is an isolated amplifier with a differential output. However, many microcontrollers only support single-ended ADC inputs. To resolve this, the differential output of the AMC1...

Cylon Vocoder wit Larson Scanner ( moving eye)
Donners Sep 21,2025
I'm a big fan of the TV series Battlestar Galactica ( BSG) and I love the robots called Cylons. The original design ( and also in the remake) included a moving red eye that later became the soul of KITT from the Knight Rider Series.The Cylons talked with a very unique sound that was produces using Vocoder technology. Maybe today, vocoders are not that special anymore because you can emulate those by using software plugin. Back in the day however, a vocoder was something special and mysteriousA v...

universal pcb
soni Sep 18,2025
Why Use a 2.54mm Pitch Universal PCB for Your Projects?A Universal PCB with a 2.54mm (0.1 inch) pitch is one of the most flexible and practical tools for electronics prototyping, DIY projects, and small-scale development. Instead of designing a custom PCB every time, this universal PCB provides a ready-made platform where you can easily solder and connect components, making development faster, easier, and more reliable. Advantages of Universal PCB:Standard 2.54mm Grid: Compatible with most throu...
