ESP32 weather station

Weather station

Another ESP32 based weather station that retrieves weather data from OpenWeatherMap via WiFi and display the infor on a 3.2″ Nextion Touch Display. It also uses the BME280 sensor for measuring weather data locally. The display is refreshed every two seconds and the weather forecast is made every hour.

Printed Circuit Boards – Things You Must Know as a Beginner

Single sided PCBs

A systematic arrangement of electrical components defined by pathways, signal traces, and conductive paths is called a Printed Circuit Board. If as a beginner you question, ‘what’s a PCB?’, then for simpler understanding, you can look at a PCB this way. Functionally speaking, the PCB offers mechanical support to electrical connections arranged in a logical manner with the help of pads, tracks, and other features. You can find the best PCBs at a cheap PCB manufacturer such as Elecrow. Types of PCB PCBs can be categorized as follows: Single Sided PCBs Multilayer PCBs Double Sided PCBs Flex PCBs Rigid PCBs Rigid-Flex

Introducing TI MSP430 Microcontrollers

MSP430 Launchpad Board

Texas Instruments (TI) is a well-known US-based semiconductor manufacturer. TI is perhaps best known to many as the manufacturer of some of the fanciest scientific calculators in the market. Of the long list of electronic devices produced by TI, microcontrollers are on the top. TI manufactures some of the coolest and advanced microcontrollers of the market today. There are several categories of micros from TI. These include general purpose low power MCUs which mainly comprise of MSP430s, ARMs like TM4Cs, MSP432s, etc, micros for wireless communications like CC2xxx series, ARM + DSP micros, DSP-specialized micros like the TMS32xxx series and
