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.

How to use C# to read sensor data from Arduino or ESPx via serial connection

When you have an old Windows machine, you can convert it into an IOT gateway.

So how can we read sensor data with our windows machine? Since our windows machine probably do not have GPIO pins, we can read sensor data via an intermediary device.

For example, we can first attach an Arduino Uno or ESP32 development board as the intermediary device to our windows machine via USB. Given that connection, the intermediary device will read the sensor data and send those values via serial. On our Windows machine, we can then run a program to read those values from serial.

So how can we read sensor data from Arduino or ESPx via serial connection on our Windows machine? Since C# is a programming language for creating windows application, we can use C# to read those data from serial.
