In this post, we’ll be taking a closer look at the ESP32-S2 hardware, and more specifically, the ESP32-S2 Mini pinout. The ESP32-S2 is based on the Xtensa® single-core 32-bit LX7 microprocessor, up to 240 MHz. The ESP32-S2 pinout consists of 43 × programmable GPIO’s pins, 2 × 12-bit SAR ADCs, up to 20 channels. The …
A thermocouple is a device for measuring temperature. It comprises two dissimilar metallic wires joined together to form a junction. When the junction is heated or cooled, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature. Basics of Thermocouples A thermocouple consists of …
In this post, we’ll be taking a closer look at the Arduino® Nano hardware, and more specifically, the Arduino® Nano pinout. Arduino® Nano is based on the ATmega328 by Atmel. The Arduino® Nano pinout consists of 14 digital pins, 6 analogue inputs, USB connection and ICSP header. The versatility of the pinout provides many different …
As you are used to, I always illustrate my projects with a scheme made in Fritzing. The standard components are usually present in the default software. But often enough there are components not present. I then make these components myself. Because I have added a whole series again, I wanted to share my own new library, and …
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, …
Year 2021 will go down in history as one of the worst in recent memory. It has been pretty eventful, to put it lightly. With the pandemic being the dominant problem, punctuated by a lot of calamities, the year felt like it came by fast and slow at the same time. For most of us, …
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 …
