This project is a small automatic cooling system for home theater rack. It supports 2 temperature sensors for different zones in the rack and 2 12V PWM fans (standard for PC case cooling).
There is a power switch connector for a switch mounted on the casing (will be designed and 3D printed later). A reset button is provided mostly for reprogramming purpose. There are 4 buttons for setting up temp...
In this project, I will go through the process of designing and making a flight controller board from scratch for a micro-quadcopter. This board will be based on the ATMega328 microcontroller and will be used to control four coreless DC motors. The whole PCB making process from designing of the schematic to [**custom circuit board**] is done using EasyEDA. If you are interested in the circuit p...
Panoramic photo robot with Bluetooth control, based on Arduino MEGA 2560
Since everything in this schematic is either public or super simple I leave it as public too.
**NOT for commercial use!**
This project of mine has just been started so there is no firmware nor software (PC, Android) available yet. Currently I don't plan to make it public like the Arduino shield design.
If you like the s...
The PCB attaches to the back of the OP-320A unit, which is a cheap operator console panel you can get off aliexpress or ebay for about $50, you remove the PCB with the unit and attach this as a replacement to give arduino compatibility.
Wiring mostly copied from teensy++ and uno so something of a mix here, Uses a standard Arduino shield header but you will definitely need to adjust your sketch...

D4 — выход «тревожного» пина, при срабатывании датчика на этом пине устанавливается сигнал высокого уровня
D5 — инверсный выход «тревожного» пина, при срабатывании датчика на этом пине устанавливается сигнал низкого уро...
This is my final design for a NIXIE clock. I have made several and this is the best one. My gift to the universe is this in the public domain. Feel Free to make one and tell me about if you like.
the arduino code is attached, I suggest you use it as a starting point for your own code. From it you can see what pin is connected to what and how I implemented the multiplexing, you may have a more ele...
This is an arduino nano based soldering station. **Not tested yet! But a very similar perfboard version is working on my desk right now **
-Designed to work with rotary encoders.
-Built in Beeper.
-Built in memory buttons to store often used temperature values.
-Built in anti prelling for the buttons. (up to 7 buttons, built in 3 buttons)
-Designed to work with a MAX6675 module for temp...
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...
Este sera la parte física o de Hardware del proyecto integrado con Visual studio mediante una aplicación Windows forms y una coneccion a una base de datos de Microsoft SQLserver, para la consulta y almacenaje de datos.
It'll be the hardware for an integrated project with Visual Studio as Windows Forms App...
Test print for the Aruino (and mega)
Every output pin has an LED, and has a switch to 5V to test if it still works (and is not broken)
and the analog pins can be attached to a 0-5V rail to test there functions too
This is a custom - Arduino uno - based circuit.
- Microcontroller: Atmel ATMega328p
- Bluetooth Module: Support HC-06 & HC-05
- Motor Driver IC: Two L293D (up to 4 DC motors or up to 2 stepper motors)
- Servo motor header
- 3 input/output pins (Can be used to connect LEDs or button SWs)
- Programmable header
- Reset button
