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...
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...
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...
For an easier use of the WT588-D module with Arduino, it was decided to create a special Shield, this allows to test the module connected to Arduino or stand-alone mode as there are also K1 to K4 keys. There is also a connector for direct connection of a loudspeaker and a connector for connecting an external amplifier.
For programming the internal memory of the WT588 module, there is a connector f...
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...

the actionoiseboard decoding audio frequencies
for to set in motion motor,
is possible to use the board for set in motion motor
from remote, with audio frequencies sent in a video call,
the board have 10 pinout i2c for to connect
programmed at will to have fun turning lights on and off or giving the motors the desired movem...
What's the use?
a PlayPad is the combination of
a joypad and an mp3player (PlayPad).
in every button there is the exact frequencies for to set in motion the motors of the actionoiseboard,
pressing each button is equivalent to playing at the execution of the exact mp3 audio frequency to move its equivalent motor in its direction.
is possible to find the audio frequencies in the website:
Un Escudo para Arduino UNO para el juego de memorizar colores "SIMON"
This is a ethernet relqay board with 2 relay, 2 inputs for 240 AC detector, 2 LEDs and 2 switch you can program many options; that consist:
Atmega 328p CPU
ENC28j60 red or blue board
CP2102 white board to program the CPU or similar
AVR STK500 or similar to copy the reiquared firmware to bootload:
Control several FAN(3 pin) via PWM
PWM from motherboard connector (4 pin) or temperature sensor - jumper selection.
-with capacitor: RPM range 50-100%, RPM sensor working;
-without capacitor: RPM range 10-100%, RPM sensor not working.
