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...
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...
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...

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...
LocoNet decoder with 8 channels of capacitor discharge pulsed outputs.
Uses Arduino Pro Mini as core.
The board is traced to be toner-transfer-friendly (thick traces, large clearance, minimum count of plated holes).
LocoNet decoder with:
* 16 LED outputs (constant current 5-90 mA, adjustable),
* 8 5V digital inputs
3.5mm screw terminals for outputs, 2.54 pins for inputs
Can be powered from LocoNet or from external power source.
Uses Arduino Pro Mini as core.
Mini shield for 16x2 display
To simplify the work, it was decided to create a small card (size 43x16 mm), a mini shield that simplifies the work.
The circuit is very simple, there are some pin strips and a jumper for the backlight, there is also a 10k trimmer for contrast adjustment.
For the connection to Arduino there is an 8-pin female pin strip on which all the necessary signals including the p...
HV UPDI (High Voltage Unified Program and Debug Interface) programmer for the new tinyAVR 0- and 1-series microcontrollers built on ATmega8/88/168/328 based on the design and the firmware by Dlloydev (https://github.com/Dlloydev/jtag2updi). The HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin without the fear of getting locked out from the MCU. It fe...
The KY-013 Temperature sensor module is part of the "37 In 1 Sensor Module Board Set Kit for Arduino" series, it is an analogue temperature sensor based on an NTC thermistor and a 10 kΩ resistor. The resistance of the thermistor varies with the surrounding temperature.
This module measures temperature from about -55 to +125 ° C with a tolerance of + - 0.5 degrees. The value is calculated using the...
This is my atmega8 (and ATmega328 compatible) development board.
As it has the uart connector, you can program it in the arduino ide, if you are into that. You just need to download the bootloader through isp programming.
(I personally prefer to do it the expert way)
I added some connectors according to what I usually use:
I2C (also pull ups)
SPI (with an extra pin for devices such as nrf24,...
