Iot patient monitoring system
electronicguru0007 Aug 22,2022
When we are talking about major vital signs of a human body, there are four major parameters that we need to be aware of, they are body temperature, heart rate, breath rate, blood pressure, and due to COVID, oxygen saturation has become a major parameter that we need to be aware of. In this tutorial, we will be making a simple Arduino Nano 33 IoT-based device with multiple sensors. The device can measure some vital parameters of the human bo...

Setting up zigbee communication with nodemcu and arduino
electronicguru0007 Aug 22,2022
Zigbee is a popular wireless communication protocol used to transfer a small amount of data with very low power. It is widely used in applications where data has to be shared among many nodes within personal space, and with the advent of the Internet of things (IoT), the application for Zigbee is fast growing. It is used in home automation, asset tracking, remote data collection, and much more. If you are already familiar with the architecture of Zigbee and Zigbee protocols, ...

Ac Dimmer Remote PCB
electronicguru0007 Aug 22,2022
The brightness can be controlled using the IR remote of TV, DVD, etc. Dimming Control system using MOC3021, BT136 Triac and a zero-crossing detector circuit based on the MCT2E optocoupler. Optocoupler provides complete isolation between the AC side and the DC controller side. So if any fault or short circuit happens on the AC side will have no effect on the controller side.In this tutorial, we will design a circuit using TRIAC and optocoupler to make a 220V AC Light Dimmer or AC Fan Speed C...

STM32F4 Black-pill: WiFi shield (WiFiNINA)
Mischianti Aug 22,2022
STM32F1 Blue-pill: WiFi shield (WiFiNINA)Complete tutorial here.First of all, read the article “STM32: use WiFiNINA with ESP32 WiFi Co-Processor”, where there are all the basics to understand this shield usage better.For me, It’s very important the network connection and network limitation on STM32 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.So I design a shield to add WiFi to my STM32F1 blue-pill.For me, It’s very important the network connecti...

PCB_PWM-Fan-Controller-with-RE
MakerIoT2020 Aug 22,2022
Last month I spent quite a lot of time on expansion modules for use with the ESP-12E I2C Base Card. While the system worked exceptionally well as a prototyping and firmware testing platform ( as originally intended ), I immediately saw that the physical size of everything ( base board, with the cards) would be a problem inside any enclosure, when used with a real-world project.At the same time, I have an ongoing need to design and manufacture a device for a friend, that will have very limited sp...

MIDI Breakout Board
Lunde Aug 22,2022
When I first started out with building the BulkyMIDI-32 (running mt32-pi), I had no idea what I was getting into and of all the modules I started building - this is the one I wish I'd started with. It was designed for use with Arduino Uno, Nano, Every and Pro Micro in their 5v variants - mostly because these are what I'm most familiar with. What it gives you is the circuits for adding 5-pin MIDI IN and OUT to your board using four cables.

Lora Communication With Network
electronicguru0007 Aug 21,2022
This was a very simple project and can come in handy for various applications. But what it can't do is establish communication with the internet for modern-day IoT applications. So in this project, we will be using the HPD13A which is a SX1276 IC-based LoRa module to establish communication with the things network, so we can use this module for IoT-related applications. So without further ado let's get right into it.HPD13A - SX1276 Based LoRa Module PinoutThe pinout of the HPD13A - SX1276-based ...

Remote Servo Actuator
Iturriaga Aug 20,2022
How does it work?The ESP8266 board (D1 mini) connects to the wifi your wifi network and the Blynk app. When a Botton on the app is actioned, the ESP sends it to the servo motor. The LM7805 transistor is used to convert the 9 volts from the battery to a useable 5 volts. All of the parts used are widely available for some cheap prices.Building and Programming:Building the Blynk app:Start a new project on the Blynk App.Name it Remote Servo Control, choose ESP8266 as the device and choose the connec...
