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...
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...
Hey, I'm Linus,
I'm currently working on a professional DIY Vending machine with 40 product trays and a change system. I'm using three PCA9685 LED Driver to control 40 360 degrees servo motor and 5 SG90 servos for the change system. I'm using a 4x4 Matrix Keypad as the input, a 16x2 I2C LCD for the interface and a standard CPU Coin Acceptor as the coin detection. I want to use the Arduino Mega a...
Test print for the Aruino (and mega)
Every output pin has an LED, and has a switch to 5V to test if it still works (and is not broken)
and the analog pins can be attached to a 0-5V rail to test there functions too
To test the series of sensors contained in the package "37 in 1 Sensor Module Board Set" which is sold by many sites it is possible to use this shield compatible with Arduino UNO original R3 and related clones.
On the board are available many connectors that are already properly connected with the digital or analog ports of Arduino.
In fact, the card, in addition to the sensors in the "37 in 1 Sen...

A board to pull the last little bit of juice from a battery (down to around 500mV or so under load) and use this to power an external Li-ion charger (at 5V). Uses an Arduino Nano to control shutdown and to track the amount of power moved around via a coulomb counter.
