STM32 SPI Communcation and Data Sent
electronicguru0007 Oct 13,2022
SPI in STM32F103C8Comparing SPI bus in Arduino & STM32F103C8 Blue Pill board, STM32 has 2 SPI bus in it while Arduino Uno has one SPI bus. Arduino Uno has ATMEGA328 microcontroller in it, and STM32F103C8 has ARM Cortex- M3 which makes it faster than Arudino Board.STM32 SPI ProgrammingThe programming is similar to the Arduino code. The same <SPI.h> library is used in programming STM32F103C8. It can be programmed using USB port without using FTDI programmer, to learn more about programmi…

Arduino NANO 33 IoT SPI Flash memory shield
Mischianti Oct 13,2022
Like the Arduino MKR WiFi 1010, the NANO 33 IoT doesn’t have Flash memory to store data. I wrote an article that explains how to interface these kinds of memory, “How to use external SPI Flash memories“, and I’d like to simplify the process of adding these chips, so I created another simple PCB shield to add external SPI Flash memory in the fastest way.The configuration is the same as the examples already posted.Read the article to have more information.From the up, you can see how the shiel…

PLC with pic16f876a pt2
crigiro Oct 12,2022
this is the second part of the small plc with pic16f876a. I made a small card with actuators and givers to be able to control motors and pumps, and to create small controls and automation systems using transistors, relays and LEDs already present in the card that must be inserted above the previous card (pt1), all powered at 12V

PLC with pic16f876a pt1
crigiro Oct 12,2022
a small plc easy to build I use a pc16f876a as a mcu, it can be programmed to control leds, relays, pumps, motors and to make small automation systems. I use the ladder language, but it can be programmed differently. powered at 5V

PhoneLocator
Andrei Florian Oct 11,2022
AbstractFigure 1: PhoneLocator’s instant responseHave you ever forgotten your phone in your friend's house? Are you afraid of an unpleasant person taking your phone? I am sure that everyone was confronted with losing or forgetting their phone. PhoneLocator aims to locate your phone (hint in the name) and send you its geolocation coordinates via email so you can recover your precious device. Thanks to Blynk, all you have to do is press a button. Note that you will need a Blynk account to operate…

Home Automation Getting Started guide
Arnov sharma Oct 10,2022
Hello and welcome back.This is a Home Automation Board that is based around the NODEMCU ESP8266 Board and 6-channel relay.This Board is controlled locally by accessing its web app via any browser, it can control 6 different outputs currently but we can add more, and it's easy to change the code for extra outputs.The goal of this project is to make an easy and simple Home Automation System that anyone can make and learn by following a few simple steps.let's get started.MATERIAL REQUIREDThe follow…
