“Pictured below is a controller we recently made for use in a poultry egg incubator, designed to keep eggs within a very narrow specific temperature and humidity range for a few weeks. This is achieved using a heater, a fan …
“One of my ongoing projects is a very low-power electronics device that supposedly runs on a single-cell Li-Ion or Li-Polymer battery for a very long time, hopefully many-many months. In my idea, the battery actually could be a rechargeable one …
“This is a system that makes it easy to find your resistors. Search at desired value, and the right drawer lights up. This system can be extended to desired numbers of drawers. Supplies: Adressable LED’s WS2812B Arduino Nano 4 …
“Welcome to this instructable where I will show you how I made this 12volts to 220volts DC-DC converter with feedback to stabilize output voltage and low battery/ under-voltage protection, without using any microcontroller. Even though the output is high …
“Actual PWM duty cycle on 7-segment LED display, driven by hardware (PL) and controlled by software (PS). This project was created for the MiniZed Motor Control Build Challenge and the final application was built on the Mini But Mighty project …
“Just in time for Valentines day, a small gadget to be given to your sweetheart: a heart that loops through multiple animations. It nicely fits on a desk or table to have your loved one remember you! This animated heart …
“This project describes how to make an Arduino-based, voice-controlled, IOT relay switch. This is a relay that you can turn on and off remotely using an app for iOS and Android, as well as tie it in to IFTTT and …
“In this Instructable, I’d like to show how to make a simple Bottle Binary Clock. This binary clock can read time information from an NTP server and clock will be updated over WIFI. Time will be shown by RGB …
“Another example of using a LCD keypad matrix 4x4 with an I2C circuit. This matrix keypad is made of 16 push buttons and with I2c communication, you just need 2 pins to manage it: SDA (A4 on arduino board) and …
“A TTL/CMOS based clock that displays the time along a 60 LED bargraph. I like clocks. I like LEDs. I like mucking around with circuits. I want to make a clock that displays the time along an LED bargraph …
