The ESP32 comes with 2 Xtensa 32-bit LX6 microprocessors. So, it is dual core. When we run code on the Arduino app, by default, it runs on core 1. In this blog we’ll show you how to run code on the ESP32 second core by creating tasks. You can run pieces of code simultaneously on both cores, and […]

If you’ve worked on electronic projects in the past, you’ve probably heard of breadboards before, and maybe even used them. But what does ‘breadboard’ mean? Breadboards can be a little confusing at first if you don’t understand the logic behind them – which is exactly why we came up with this blog to get you
In this blog we look at the BME680 Integrated Environmental Sensor with Arduino Nano microcontroller. The BME680 is a gas sensor that measures relative humidity, barometric pressure, ambient temperature, gas (VOC Volatile Organic Compound) and IAQ (Indoor Air Quality). Because the pressure varies with altitude, The sensor can be used to measure estimated altitude. Using

In this blog we look at the Sensirion SHT3x Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT30 sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses. Unlike earlier SHT sensors,

In this blog we look at the BH1750 light intensity sensor breakout board with a 16 bit AD converter built-in which can directly output a digital signal, there is no need for complicated calculations. This is a more acurate and easier to use version of the simple LDR which only outputs a voltage that needs

Since the corona virus I have become increasingly aware of my environment. I also started to delve deeper into my living environment and in particular the air quality. I Already wrote a blog about the NASA Clean Air Study, this blog explains how you can clean your indoor air with plants. But I don’t know how

Through some researches I did online on how to minimize components use, I stumbled with using an ATTiny13A chip to be used in the project. And through some more researching, I decided to have my new project done using the ATTiny13 Chip. ATTiny13 Chip I bought these chips from Ali-Express. First I need to study

The I²C bus communication is one out of three possible communication protocols, the ESP8266 is able to communicate with other devices like OLED displays, barometric pressure sensors and so on. The two other communication protocols are SPI and UART. I²C stands for Inter-Integrated Circuit was invented 1982 by Philips Semiconductor (A Dutch company), now NXP
