This is an Arduino camera module, using the surveillance camera's digital image processing chip-OV0706.
FreeRTOS, simple, easy to use, robust, optimised for Arduino IDE.
Full access to FreeRTOS capabilities, within classic Arduino environment.

The software library to calculate moon age, sunrise and sunset time.
FreeRTOS, simple, easy, robust, and optimised for Arduino IDE. Using FreeRTOS Semaphores to share and protect physical resources.
Things you should know using ESP8266 WiFi module for its safety and easiness as it's very delicate module to use.

Keypads are used in all types of devices, including cell phones, fax machines, microwaves, ovens, door locks, etc.
Did you ever wonder what happens between the time you click on "Upload" and your sketch starts running? Here's how you can find out...
nRF24L01 radio transceiver provides very efficient and inexpensive way to establish communication between microcontrollers.

Build a treasure chest or use an existing storage box, attach a push-button quadrature rotary encoder (endless spinning dial) and lets go!
Learn about photoresistors and the process of characterizing their response to light intensity.

In this project, I am going to make a LAN cable tester with just a few basic electronics components. It cost me just a bit over $3.
After you read this post, your projects will never run out of power after a power outage.

A digital device that visualizes analog signal.
I built the right and left mouse buttons with wall switches.
Use FreeRTOS (simple, easy, robust, & optimised for the Arduino IDE) to reduce the power required for battery or low power applications.
Back when I first started working with micro controllers, the most annoying thing was when a tutorial I'd spent hours following didn't work.
by Dante Roumega
This project requires no wiring and is really cool it is able to decode and encode a language that i made up called HEX and Binary.
