Board to connect a Minitronics to a SmartLCD
Vactrol bandpass filter with F,A, Q stored in Arduino Mega
Automatic Chicken coop door closer
UPS will trigger PC sleep button after 1 minute of UPS power down.
Using audio from receiver, automatically tune MFJ 1788 mag loop antenna.
This is a conversion of my project C_meter_ATtiny2313
from Attiny2313 to shield for Arduino uno R3. All describe about a techique is actual.
Build is in progress.
This a Basic Triac On-off board that can be managed from 3v to 6v.
This is a small pcb that is designed to be used on an electric go-kart to display a stopwatch, motor RPMs, and cart speed as well as record this data on an SD card with a time stamp for analysis. The project is Arduino based and is ran off of 7-59 VDC or directly from a 5V source through any of the 5V or VIN pins on the data logger shield (this is not a protected input). It is designed to have w...
This is a project which is reproduced from arduino.cc Arduino Pro.Using EasyEDA to re-layout the PCB.
BTW, This project is **not imported** from an Eagle, I have done some modify.
Repurposing an old laptop power supply (18vdc) and dozens (actually - hundreds...) of white LEDs from old solar powered Christmas lights, to build an illuminated 'Merry Christmas' sign (a la Big Clive's Arcade sign).
The LEDs are made into strings of 5, each with a current limiting resistor, and a switching transistor to control the string. The transistors are switched from the outputs of multip...
The Arduino platform has become quite popular with people just starting out with electronics. It is an open-source hardware design, based on microcontroller board designs and provide sets of digital and analog I/O pins that can be interfaced to various expansion boards ("shields") and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading pro...
