Electronics Project Powerbank
Taste The Code Aug 26,2022
The PCB allows you to solder a CB-18650-PC2 battery holder and a power bank module next to it so you can create your own power bank. Additionally, the PCB has mounting holes for an extra resistor in case the project does not draw sufficient current to keep the power bank on.You can check out all of the details on the board and how to use it in the video below.

Iot AC Current Measuring System
electronicguru0007 Aug 25,2022
Smart power monitoring is getting increasingly popular to improve energy efficiency in medium/small scale industries, multi-story buildings, etc. We have previously built a smart energy meter which can measure power and report usage online. While this type of system is popularly used in energy meters, another most commonly available technique to measure current is by using a current transformer (CT). CT can detect and measure AC current in machines and other AC appliance...

Make your own branded ESP32 development board with PCBWay!
mohdazhar Aug 24,2022
What about making your own custom PCB boards with your own branding? Doesn't that sound nice? PCB manufacturing has now become easier than ever before with the coming of brands like PCB Way. We can order our PCB just like any other shopping experience, by uploading the design in Gerber file format.What is a Gerber file? Gerber is a file format for printed circuit boards. It contains the data of the different layers of the PCB as per the design, Copper layers, solder mask, legend, drill data, etc...

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...

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...

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...
