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**][1] 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...
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...

12V 50Ω solenoid driver. Can be chained to control more than eight solenoids.
The solenoid driver uses a shift register with a latch to control its outputs such that a singe microcontroller (e.g. Arduino) can control large amounts of solenoids whilst only requiring 3 output pins.
An Arduino/ESP8266 display board for 3x2 788BS red led matrices connected to max7219 drivers.
The IREG is higher than usual to reduce brightness, use a smaller resistor (maybe 30/40 K) for daylight applications.
Work in progress, comments are wellcome.
When used with MD_MAX72XX and MD_Parola libs this matrices are not one of the supported hardware types, but I was able to wire 1 and 1+1 on a bre...
USB to serial converter based on the new ch330 chip with 5V logic.
It is simple module to control RGB strips. You can use diferent MOSFETs (but 3 - sourse 2 - draine 1 - gate).[Sketch for Arduino](https://github.com/ParasolkaJeck/Arduino_RGB_controler). You can don't use diod.
PCB supporting the Arduino Nano.
Provides connects for four A4988 stepper motor drivers, two PWM controlled mosfets, two termistor sensors, three limit switches, probe, and the appropriate buttons.
To be used with Teacup for 3D printing and grbl for CNC machining, both being configured to use the same pins.
One PWM channel doubles as spindle control for CNC and hotend heater control for 3D...
Simple breakout board for the ATtiny10 microcontroller.
