Why get a Raspberry Pi?

If you are in the computer technology industry, then you most probably have heard about the Raspberry Pi.

When a Raspberry Pi was first launched in 2012, there were limited USD 35 alternatives for Raspberry Pi. Therefore, buying a Raspberry Pi is a no-brainer to get started with Internet of things (IoT) projects. A Raspberry Pi would be an affordable ticket to the world of IoT.

However, as newer single board computers get into the market, it becomes harder to make a buying decision. Especially if you habitually practice delay gratification, you may face quite a bit of procrastination in getting a Raspberry Pi.

So why should you get a Raspberry Pi?

In case you are deciding whether to buy a Raspberry Pi, here are some reasons for you to get one.

An easy way to install Raspberry Pi OS - using Raspberry Pi Imager

Once got an microSD card for your Raspberry Pi in your mailbox, you can install an operating system to run it.

Typically, we download a Raspberry Pi image and use one of the imaging software to write it to our microSD card.

When the Raspberry Pi Imager came into the picture, the download step is consolidated into a single workflow.

Given that, this is how you can use the Raspberry Pi Imager to install Raspberry Pi OS.

How to show the temperature and humidity of your room on a Heltec WiFi Kit 32 attached to a DHT11 / DHT22 sensor

When you have a DHT11 / DHT22 sensor, you can measure the temperature and humidity of your room. If you attach the sensor to a Heltec WiFi Kit 32 development board, you will be able to put up the readings on a 0.96 Inch OLED screen.

Given these points, let's look at how we can show the temperature and humidity readings of your room on a Heltec WiFi Kit 32 development board attached to a DHTXX sensor.

Why get a Wio Terminal for your next IoT project?

If you have 30 USD and is looking for a microcontroller, then you will want to consider the Wio Terminal.

Since Seeed Studio had kindly sent me one for free, I got to picture my 30 bucks alongside the box:

Although 30 bucks is not a lot of money, it is good to know what the Wio Terminal is capable of before buying. When we do so, we can prevent adding on to that electronics stockpile which is collecting dust in the house.

Given these points., let's look at why you will want get a Wio Terminal for your next IoT project.

That's all for now...
