“Display weather information and activate RGB color patterns via this shield, including built-in BMP280 and photoresistor, designed by me. Description Even though it is my first attempt at designing a PCB board and layout, I wanted to share with you …
“pH meters are scientific instruments used for measuring the activity and concentration of hydrogen-ions in water-based solutions, with the aim of indicating its acidity or alkalinity expressed as pH values. They find application in water & wastewater treatment, pharmaceuticals, chemicals & petrochemicals …
“This project is without doubt the most complex I have undertaken, with sixteen IV-11 VFD tubes, two Arduino Mega cards, ten LED Neon light circuits, a servo, an electromagnet, two MAX6921AWI IC Chips, five DC power supplies, a HV …
“Replace an unreliable cheap pressure switch with an Arduino-controlled high current relay. This whole project started when one of my air compressor at work started eating pressure switches and burning out the compressor unit, I replaced the first one with …
“In this project, we will be making a benchtop pH meter using the gravity analog pH circuit and probe from Atlas Scientific and an Arduino Uno. Readings will be displayed on a liquid crystal display (LCD). MATERIALS 1 - Arduino Uno …
“This is not the first raspberry internet radio, i know. But this one can be build by almost anyone. No programming skills or soldering skills needed. Just buy the components, connect some wires between them and thats it!. Oh, and …
“Using a D1 mini to download and show one-week weather forecast data on an LCD 20x4 display. Sometime ago I’ve come across MetaWeather, a weather data service requires no authentication or registration. I figured I’ll make a little …
“Everyone knows the game “I Spy” from his childhood. Let’s build an electronic version with the Arduino. For the prototype you need an Arduino (I’m using an Arduino Uno here), a color sensor, a display (with I2C connector …
“Use an ESP32 to control anything from stepper motors to LED strips with easy-to-use and modular code. It can connect locally or externally. Idea Creating a system that can handle large amounts of sensor data, have multiple outputs, and connect …
