Quick References

As a constant learner, I get to touch upon many ideas in different areas. This category is for me to capture those ideas which I felt people may reference to get ahead of their tasks. Most of the time, I do come back to this section of my blog to remember what I had learnt in the past.

How to use a ESP32 development board to read temperature and humidity from a DH11 sensor

When you have a DHT11 sensor, you will be able to get the temperature and humidity of your environment.

Given that, this post shows how to use ESP32 development board to read temperature and humidity from a DHT11 sensor.

How to prepare a virtual environment to run a gpiozero based project on Raspbian Stretch

When you use a virtual environment to run your application, you isolate the dependencies in its own container.

In such a situation, you can ensure that your application can run alongside other applications with incompatible dependencies.

Therefore, I always favour the use of virtual environment for running my Python applications.

With this in mind, this is a story about preparing a virtual environment to run a gpiozero based project on Raspbian Stretch.

Enabling ESP32 Development on Arduino IDE

When you want to implement a low cost IOT solution with bluetooth interface, you can consider using a ESP32 development board. In addition to the bluetooth interface, the ESP32 development board also includes a WiFi interface.

In order to run a program on the ESP32 Development Board, we will need to write our program into the flash memory of the development board. Since it is easy to write code and flash programs with Arduino IDE, it is a good tool to use with the ESP32 Development Board.

In case you need it, this post shows how to enable ESP32 development on Arduino IDE.
