ESP32 Weather Station
electronicguru0007 Aug 23,2022
In this project, we will learn how to create a weather station, which will display reading from a BME280 module and live weather data from OpenWeatherMap API in a webserver. The device will get temperature, humidity, barometric pressure, and altitude from the BME280 sensor and external temperature, humidity, weather condition, and sunrise and sunset from OpenWeatherMap API. We can see those reading in a web browser. BME280 Temperature, Humidity & Pressure SensorThe BME280 is an integrated en…

NRF Data Transfer Via 2 Boards
electronicguru0007 Aug 23,2022
There are various wireless communication technologies used in building IoT applications and RF (Radio Frequency) is one of them. nRF24L01 is a single-chip radio transceiver module that operates on 2.4 - 2.5 GHz (ISM band). This transceiver module consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, a modulator, and Enhanced ShockBurs protocol engine. Output power, frequency channels, and protocol setup are easily programmable through an SP…

Fume Extractor
Arnov sharma Aug 23,2022
Greetings.So here's something COOL, a DIY Fume Extractor made completely from scratch.The Goal here was to make a simple to make Fume Extractor for daily use.Its body is made up of 3D Printed parts and the motor controller is based on Attiny13 MCU that uses a Mosfet IC to control the Motor Via PWM Signal that we control with a button.It has three modes for working, One first button press, Motor Runs at 100% Speed.The second Button press reduces the motor Speed by up to 50%, Third Press turns Mot…

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 body. The device will be like a DIY multi-para monitor th…

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, then you already kno…

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 Contro…

STM32F1 Blue-pill: WiFi shield (WiFiNINA)
Mischianti Aug 22,2022
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.PCBThe PCB is quite simple, I also add an interface to update the firmware over esp32. Strangely, esp32-s seems …

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.
