3 line to 32 line output expander
Yap Mar 04,2022
This project is described at Hackaday.The minimum lines required to use this board are: GND, SER (data), SRCLK (shift), RCLK (strobe). Vcc depends on the power arrangement. You should jumper the ~OESEL (output enable select) to ground if you don't wish to disable the display by signal, or vary the output with PWM, from a controller. The ~SRCLR input is only needed for resetting the output by the controller.This board is designed with optional aspects you can choose to include or not:As mentioned…

WeMos D1 (esp8266) Ebyte LoRa shield (10Km) with HardwareSerial and voltage regulator
Mischianti Feb 24,2022
The new shield is similar but has more features here than the breadboard schema, even if it is limited to 3.3v of supply to the LoRa device.EByte LoRa E32 Wemos D1 shield to hardwareserialAs you can see now, there is a voltage regulator to power the e32 device, and RX, TX is connected to TX and RX of microcontroller, a pin is free to connect Serial to USB to debug on Serial1.So the PCB schema become soEByte LoRa E32 Wemos D1 shield PCB to hardware serialMore complex and with more pins and button…

WeMos D1 (esp8266) relay shield
Mischianti Feb 18,2022
WeMos D1 3v module relay shield at work main.One of my project’s most used components is undoubtedly the relay; its working is quite simple; you can find It as a module or only the relay.You can find multi-voltage relay modules on AliExpressThe only problem you can have is that relay needs some power to be activated, so It’s preferable to use a transistor like 2n3904.You can find 2n3904 transitor on AliExpressHere is a simple breadboard connection schema; as you can see, I use a microcontrolle…

3 speed Fan controller with Local control
MakerIoT2020 Feb 17,2022
Bymakeriot2020 FEB 17, 2022 ESP8266, IoTA typical desktop oscillating fanDesk or floor-standing fans are one of those appliances that will be present in almost every home or office. Some of the newer ones may already have remote control of some sort, while the older models won’t. It is however quite easy to do a retro-fitted controller to most of them, and at the same time, give them some (limited) intelligence.Your typical oscillating fan does not have a lot of intelligence built-in. They nor…

Relay Shield PCB Design Useful for IoT Applications
Arshmah Shahkar Feb 08,2022
Every household has electronic devices which are a major part of our everyday life like dishwashers, washing machines, boilers (water heaters), kettles. All of the previous devices are a combination of mechanical – electronic – power sets. The main part of devices operation is electrical power. It’s well known that AC electrical power is dangerous for humans and that’s exactly the type of power for devices operation. For example, if you leave your kids at home alone, they could turn on, by a…

All In One Arduino PCB Board Design
Arshmah Shahkar Jan 31,2022
The All in one Arduino board is designed to provide the facility to the users of doing multiple projects at a time with efficiency. Those who are doing projects on Arduino can understand the need for this board. If u try to connect multiple components to the Arduino it will not work efficiently with all components at a time with either 5V or 9V regulator, you have to do it turn by turn otherwise you will not get accurate results. While with this Arduino board a user can easily connect more than …

8266-12E Port Expander Card for the MCU-8266-12E IoT Controller
MakerIoT2020 Jan 23,2022
IntroductionAfter quite a few experiments, and playing with a lot of ideas, we have finally produced and tested an almost final prototype for the MCU-8266-12E IoT Controller Port Extender Card. While the baseboard already has quite a lot of free GPIO pins for additional sensors and devices, It did however have quite a few issues, namely a lack of sufficient Power outputs, difficulty access to the I2C bus, as well as only 2 relay outputs. Granted that you do have access to unused pins on the PCF8…

Rudolph the Red Christmas IOT Card
kadu Jan 06,2022
Hi, I'm a Rudolph and you know me from Santa's Stories, and I'm here to help him to bring messages from all around the world directly to your Christmas tree.Nowadays with some travel restrictions, Santa's asked me some genial Ideas to make happier people, and looking at my desk I found some DIY materials and with some effort, I've created my first IoT device (I'm fancy). Let me show "my precious":I've got an Espressif MCU called ESP32 (in Node32s dev board) and an Oled display (SSD1309) with 2.4…
