PCF8574 x8 GPIO Expander with VGA/I2C Port
Mer08_ Sep 29,2022
This breakout board is made for all of your pin-hungry Arduino / Linux projects! I decided to make it because I wanted to start learning about PCB design and wanted to have GPIO pins on my Linux laptop. It's a bit difficult to use it on Linux, so here is a tutorial on Arduino and Linux (the website is in WIP so please forgive me for its awful look). Here is a video showcasing the Linux part hooked up via the VGA port:

Egg Incubator with PID controller
isnannabawi Sep 28,2022
Egg Incubator with the PID controller corrects the shortcomings of conventional incubators that cause egg failure. This board is using simple components(through-hole components) and only 1 layer of PCB. It can be easier for anyone to assemble and produce.A conventional Egg incubator is an egg incubator with a digital heater control. It will be turned on when the temperature reaches below the minimum threshold and it will be turned off when the temperature reaches above the maximum threshold. Unf...

Baby Monitoring System
mohdazhar Sep 27,2022
We are very well familiar with the hurdles faced by Parents to nurture their infant and especially in case if both the Parents are working. So, we found the need to develop something unique that can help Parents to have a continuous surveillance on the baby and can notify about the same. Thus, we have come up with an idea to design a Baby Monitoring System which will help the Parents to monitor their child even if they are away from home. The design uses the technologies which include GSM module...

Automatic Fish Feeder Using Arduino Nano
Lutfi Sep 26,2022
In this article I will make an automatic feeding device for fish in an aquarium. This tool uses arduino nano as the main controller to drive the servo in the feeding process. I will use this tool in an aquarium that I just bought a few days ago. I worry if I forget to feed the fish when I go out for activities. so I hope with this tool the fish can eat regularly.Component and Material1*Arduino Nano1*RTC DS 30171*Step down DC to DC LM25961*470u/10V1*DC Jack3*Tacth Switch1*Buzzer1*5V Relay4*3mm LE...
