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...
Originally developed to test an aircraft actuator, this project uses the Holt Hi3593 ARINC429 driver IC connected to an Arduino Uno shield. Supporting 1 transmitt channel and 2 receive channels, its easy to use.
Arduino software has also been written and tested (attached). Transmitt commands and receive events are sent and received through the USB serial port on the Arduino Uno. Transmit in hexi...
This is the analogue part of the circuite for my Arduino battery charger project.
The software can be found at https://github.com/GarethDaviesLondon/PWM-Charge-Controller-Arduino.
The pin outs refer to an Arduino Nano.
The key to this project was to make the Nano go to sleep when the sun wasn't shining.
This project is a simple programmer for burning a bootloader on the ATMEGA328P using arduino as ISP before it is soldered unto a board. The instructions here https://www.instructables.com/id/Burn-a-New-Bootloader-Arduino-Pro-Mini/ for using an Arduino as ISP can be followed. Please note that this design saves you from having to make all the connections as shown in the instructable. Simply place a...
A multipurpose LoRa microcontroller board based on the Atmel 328P microcontroller with an RFM95W LoRa module attached. This version also has an onboard solar power LiPo charger for the integrated 18650 LiPo battery.
# **THE RANDOM MACHINE**
Ce projet a été conçu et réalisé par l'équipe de conception électronique et mécanique du collège Jean-Georges REBER se situant à Sainte-Marie-aux-Mines du Val d'Argent. #
Le projet est une boîte fermée pouvant s'ouvrir après y avoir composé une combinaison aléatoire sur ses cinq bits. Le code composé par le joueur est directement affiché par les leds se trouvant au dessu...
PCB muon detector
Schematics designed by Robert Hart:
Thanks to Robert Hart for his fantastic ideas, please check his site for further experiments:
This project uses 3 Geiger tubes to create a muon detector, it also uses a step up boost DC-DC to convert from 5V to 400V for Geiger tubes.
This main PCB has...
