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...
This is an attempt to create your own version of the calculator on the ATMEGA8 chip.
The purpose of the conclusions of the microcontroller is seen in the circuit.
The handling of 20 keys is described on my blog - http://un7fgo.gengen.ru/?p=2127 (I apologize, only in Russian).
Infrared Sensor Module has built-in IR transmitter and IR receiver that sends out IR rays and looks for reflected IR rays to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.
It is Arduino and Rasberry Pi compatible b...
Не нашел у китайских производителей универсального переходника под ATTINY13/85, ATTINY2313/4313 и ATMEGA 8-168-328 в DIP-8-20-28 корппусах.
Поэтому нарисовал сам такой переходник и собрал его на монтажной плате.
На переходнике выведен ISP-интерфейс для программирования мелких микроконтроллеров и записи Arduino-bootloadera для микроконтроллеров серии ATMEGA.
Так же для них выведен UART, с целью п...
This is a simple Timer switch using Arduino and DS3231.
Change the relay type to your specific load.
