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...
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...
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...
An Arduino Micro based automatic plant watering system.
1. Capacitive soil moisture sensing
2. Configurable minimum and maximum soil dryness setting
3. Water overflow sensing
4. Reservoir water level sensing
5. ESD protection on external sensors
6. Reverse and over voltage protection
7. Over current protection
This is a LoRa node, powered by the ESP32 WROVER-B microcontroller. ESP32-WROVER-B is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding. ESP32-WROVER-B features a 4 MB external SPI flash and an additional 8 MB SPI Pseudo static RAM (PSRA...
This includes all of the electronics for the go-karts used for http://evgrandprix.org/ races. This includes a general schematic for the go-kart itself, a schematic for the "PEM Box", and a previous design concept that has since become obsolete.
Discharge up to eight 1.5V alkaline cells independently with constant current and measure the time = capacity.
Based on Arduion Nano.

EN - Used to program custom functions in it and be able to perform NAV lights, dual servo sequences, sensor triggered actions and similar simple tasks. It should be programmed with the Arduino IDE after installing the ATTiny Core in the board's manager - https://github.com/SpenceKonde/ATTinyCore ...For easy programming use the Uno shield found here https://easyeda.com/Joyvel/programing-for-attiny-...
This is the code I use for the clock. Feel free to change it in each manner your want. ATTENTION: Dont use the POV Clock_old. I use it for backup purpose only. It wont work! The file POV Clock_new and POV_Clock_new_SSD1306 are working well and are fully tested. But i dont take any responability if something dont work like you want. For example: the optocoupler is tricky. Maybe you need to adjust t...
Preliminary edition of the hardware platform for Ethernet connected IoT devices with configurable additional ESD protection. Has 40 pin application interface. Based on STMicroelectronics STM32F405RGT6 microcontroller and Microchip ENC28J60 IEEE 802.3 controller.
Order the design to me.
