Gust MEES's insight:

How-To transform an LCD1602 SPI Sketch to an LCD1602 I2C Sketch We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it…

If you’re ever wanted to make something awesome, but thought that you just didn’t have the right tools to do so, this soda fountain by “The Wrench” could provide the needed inspiration.

The project uses an Arduino Nano to control a small air pump via a relay, which turns on when a glass is the correct dispensing position. This pushes air into a sealed soda bottle, and soda is pushed out of another tube to equalize the pressure.

Gust MEES's insight:

Adafruit LED backpacks make it incredibly simple to add small bitmapped displays to a project. Each requires just four wires: power, ground and two communication lines to a microcontroller.

Two common questions we receive:

How can I use more than one 8x8 matrix backpack in an Arduino sketch?

Can I have two (or more) matrices always showing the same image?

This tutorial demonstrates both.

We’ve had spooky Halloween displays on the brain lately, but the concepts here are equally applicable to more innocent schemes!

BBC Micro:Bit board was first announced in July 2015. Designed for STEM education, the board was then offered to UK schools in March 2016, and a few months later UK store would start selling it worldwide. It’s now available pretty much anywhere, and you can likely find it in a local store or online.

The Thai government must have seen this, and thought to themselves “If the British can do it, we can do it too!”, as the National Electronics and Computer Technology Center (NECTEC) part of Thailand’s Ministry of Science and Technology designed KidBright32 board and courses to teach STEM to Thai students.

Exchange any data between Blynk app and your hardware.

What is Virtual Pins

Exchange any data between Blynk app and your hardware

Virtual Pin is a concept invented by Blynk Inc. to provide exchange of any data between hardware and Blynk mobile app.

Virtual pins are different than Digital and Analog Input/Output (I/O) pins. They are physical pins on your microcontroller board where you connect sensors and actuators.

Blynk lets you control any hardware connected to Digital and Analog pins without having to write any additional code.

For example, if you need to turn On/Off LED connected to Digital pin, you don't have to write any code:

Just use BlynkBlink code for your hardware.
In the Blynk app - add Button Widget and set it to pin D8
That's it! No additional code is required. Simply press Play in the app.

In this new tutorial on Cayenne IoT, we will learn how to control an articulated Pan-Tilt PTZ SG90 system in WiFi. In the previous tutorial, we saw how to do with the Blynk library and application. Cayenne IoT is fairly similar. It is necessary to pass through the servers of myDevices.com which can cause a small delay of latency (quality of Internet connection, server load …).

Gust MEES's insight:

The dot matrix that we’re going to use in this guide is a 8×8 matrix which means that it has 8 columns and 8 rows, so it contains a total of 64 LEDs.

The MAX7219 chip makes it easier to control the dot matrix, by just using 3 digital pins of the Arduino board.

I think the best option is to buy the dot matrix with the MAX7219 chip as a module, it will simplify the wiring. You can check the dot matrix at Maker Advisor and find the best price.

You can control more than one matrix at a time. For that you just need to connect them to each other, as they have pins in both sides to extend the dot matrix.

How to buy a registered UK driver's license with documents everywhere
Our company works in partnership with 4 driving schools in England,Northern Ireland,Scotland and Wales where hundreds of driver’s licenses are being issued in England each year. We have realized that some of these cities are too far for some of you to attain the theoretical and practical exams and some people are so busy at work and has no time to attend a driving exams. We enroll you to one of these driving schools and your files are treated like any other file due to our partnership with them.
How to apply for copy certificates
We encourage you to apply for a replacement or copy of a birth, death or marriage certificate directly from the General Register Office and not from the Royal Borough of Greenwich.

Reading PIR Sensors
Connecting PIR sensors to a microcontroller is really simple. The PIR acts as a digital output, it can be high voltage or low voltage, so all you need to do is listen for the pin to flip high (detected) or low (not detected) by listening on a digital input on your Arduino

Its likely that you'll want reriggering, so be sure to put the jumper in the H position!

Power the PIR with 5V and connect ground to ground. Then connect the output to a digital pin. In this example we'll use pin 2.

An 8×8 dot led matrix is a very interesting device because with proper instructions the individual leds or any group of leds can be programmed to fire. This characteristic, plus the feature that up to eight modules can be daisy chained, forms the basis for a nearly endless series of visual effects. Here we discuss the very basics of working with one MAX7219 dot led matrix module. A simple sketch is provided that creates a ‘smiley’ followed by a simulation of a bouncing ball.
