Arduino Based Weather Station
Poudel Sep 12,2023
IntroductionAn Arduino-based weather station using a DHT11 sensor and a 16×2 LCD is a compact and accessible project for measuring and displaying real-time temperature and humidity data. The DHT11 sensor collects environmental information, while the LCD display visually presents it in a user-friendly format. This project serves as a hands-on introduction to Arduino programming and sensor integration, making it an ideal choice for beginners interested in DIY electronics and weather monitoring.NOT...

RPi Color Organ V2 Gerbers Sept 5
Jason Sep 06,2023
An educational project for Audio, using an XY-P40W Bluetooth receiver as the audio source. The circuit filters the Class D amplified signal back to a classic audio waveform that is fed to RC filters (high/medium/low frequency) which then drive LM3914/3915 LED driver circuits to achieve a VU meter effect. The reference voltage for the 3914 is adjustable with a pot.It also includes an electret microphone circuit to respond to ambient noise and a Raspberry Pi Pico board to sample the audio waveform...

Mechanical Mask
Malik Sep 04,2023
IntroductionThis project is the design of a smart mechanical mask that can close or open autonomously. I got the idea to make this during the pandemic and it works fairly simple. The outer shields of the mask are moveable and when someone comes near within a certain distant from the mask it closes and alternately opens up when no one is in the proximity. To achieve this I used a Proximity Sensor and a Passive Infrared Sensor (PIR Sensor) where the proximity comes into ac...

Buck Switching Regulator 7V to 40V DC to 5V DC fixed using the LM2575-5 regulator
Amaury Sep 03,2023
This is a simple but very useful project when working with electronic devices that must be powered with 5V DC and require stable power without electrical noise.Perfect for powering development boards that use 5V DC for microcontrollers and sensors. This regulator has a wide power supply range that goes from 7V DC to 40V DC, and a fixed output delivers 5V DC and 1 ampere.It has a green LED indicator to alert that the regulator is working and that it is safe to connect devices to the output.Full d...
