Have you ever walked around a house, eager to know the ambient temperature, humidity and air pressure? Have you ever thought about capturing these data with a small remote control platform? If so, this project from [TUENHIDIY] will be exactly what you have been looking for. 

This small remote control car is built around the Seeed Wio terminal. This is a microcontroller platform with a connected screen, as well as built-in wireless hardware and Grove connectors for connecting external modules. Therefore, the car adds a DHT11 temperature and humidity sensor, and a BMP280 barometric pressure sensor using Grove connector.

Driving the car is done through the Blynk smartphone app that communicates with the Wio terminal. The small DC motor on each wheel is driven by the DFRobot four-motor shield. Through the built-in screen, the remote control car displays the commands received from the smartphone application, as well as the temperature, humidity and pressure of the surrounding environment.

We really like the simple PVC-based chassis design. This is a simple project that demonstrates how to build a Bluetooth-controlled car. The data collected by the sensor can also be seen on the smartphone app, so if you need to sample the conditions in the next room without leaving the sofa, you can do that easily.

Projects like this are a good way to become familiar with the use of motors and sensors. It will also become a good foundation for the development of simple robots. We have also introduced [TUENHIDIY]'s work before, such as this excellent rotary plotter that can draw on bottles. Video after the break.

I studied Blynk. This page is a Javascript white hole (I disable Javascript most of the time).

Looking at the source code, I welcome such a thing (note the use of square brackets instead of pointed ends)

I will not touch them with ten-foot poles. Wear dangerous goods gloves and masks. No, sir.

Oh no, not the horrible Facebook pixel...tinfoil hat anyone?

This is the first shopping season music I heard.
