Arduino UNO Components library

Components_uno

pighixxx.com has published Arduino UNO components in vector format.

As promised, I publish the first components library to make pinouts.
In particular it’s a library dedicated to Arduino Uno Boards, clones and related projects.
The file contains several vector formats and any component can be expanded (For example the Atmega328 with and without socket)

PCB Business Card

7445701462922543413

alex.puffer @ hackaday.io designed a nice PCB business card with onboard 555 timer IC.

I decided I was tired of paper business cards, and wanted something more fun (and more impressive to show off). Having a PCB business card is also a perfect portable portfolio, showcasing my design and layout skills.

This project will span the first and all future iterations of my personal PCB business card. Ver. 1 starts off slowly with a pilfered 555 schematic but moving forward, things should get more interesting!

Arduino ESP8266 Tutorial: Send an email easily with your Wemos D1 board using a PHP script!

educ8s.tv uploaded a new tutorial on their youtube channel.

In this video we are going to learn how to send email using an ESP8266 based board like the Wemos D1. As you are going to find out it is very easy and it won’t take us more than 10 minutes.

Having a WiFi enabled board, like the ESP8266 enable us to do many more things. I wanted to learn how to send emails from the Wemos Board in order to get reports from my projects to my email account easily. As you are going to find out, it is very easy!

I have built a simple project in order to demonstrate what I mean. I have connected a DHT22 temperature and humidity sensor, and when the project boots up, it measures the temperature and the humidity and sends the data to my email address! This functionality can be very useful in some projects. As you are going to find out is very easy add such functionality in your Arduino projects. But let’s see how to build this project.

TEA5767 FM Radio With Digital Volume control

F9O5RKQIQK3SEUY.MEDIUM

niq_ro @ instructables.com show us how to build a FM radio using Arduino and TEA5767 module.

This version of FM radio with TEA5767 with digital volume use Arduino Uno development board instead Arduino Mega like in previous artilce.

Digital volume in 15 steps is made with MCP4261-502E/P dual digital potentiometer who work as real potentiometer (logarithmic style)…

Able to fit in the palm of your hand and provided with several changeable tips, the 3DSimo Mini allows you to 3D print using one of close to a dozen different materials as well as solder, burn, and cut foam.

“We created the 3DSimo Mini to be the ultimate creator’s tool,” says David Paskevic, CEO of 3DSimo. “It is more than a 3D printing pen. Immediate uses include extensions for burning, foam cutting, and soldering. In the future, we will incorporate additional functionality to the pen, such as drilling, making it a practical tool for creators of any skill set. The Mini is a tool that can be used for all creative projects.”
