Coil Winder PCB
Curious Scientist Sep 25,2021
This PCB is used to populate the necessary electronics for my custom coil winder circuit. The circuit is built around an STM32F401-based microcontroller. The user has two buttons and a rotary encoder with a switch to navigate in the menu displayed on a Nokia 5110 LCD. The two stepper motors (feeder and main shaft) are driven by a DRV8825 stepper motor driver. The PCB also has MP2315 voltage regulator that converts the input voltage to 3.3 V which then powers the microcontroller, the display, the...

Weather Station Using Arduino and NodeMCU
Adhikari Sep 25,2021
In this tutorial I am going to show you guys how to make an Arduino or NodeMCU based Weather Station using DHT11 or DHT22 temperature and humidity sensor and display it using an OLED Display. DHT11 vs DHT22The DHT11 and DHT22 are both low-cost very basic and slow temperature and humidity sensors which can be used for basic data logging.Despite being slower, they are very stable and consumes low power and provides relatively high measurement accuracy. The single-bus digital signal is output ...

Infrared Board
Umm.Engineering Sep 23,2021
This is a reshapening of a typical infrared module with two signigicant changes:The IR-LED and Photodiode positions are swappable by means of bridging solder jumper pads.The design uses a Single *331 comparator rather than a Dual *393 type. This choice was mostly one of OCD.

Arduino Rev3 Shield - Basic components
jimaro2008 Sep 23,2021
This design has long wanted to do so because when someone is learning or wants to use some basic component quickly this saves some time since it is only to embed the cables in the places already arranged.Is a shield for Arduino Uno R3 that has a greater number of power pins, in addition to facilitating the connection of several sensors and actuators such as:-Passive buzzer..A connection for a servo motor a connection for a 5v dc motor with the help of a 2N3904 NPN transistor. -It has the co...

Mechanical Macro Keyboard Music Maker
Jeremy Cook Sep 16,2021
Computer macro pads/stream decks/auxiliary keyboards normally control computer input functions with the press of a key, making your life easier. The JC Pro Macro takes things one step further and breaks out several GPIO pins from an Arduino Pro Micro board, allowing for control of things in "real life."In this project I hook up a small speaker for tone output, along with a small solenoid to drum out a beat. Solenoid actuation is assisted by an EZ Fan2 transistor board, which handles the higher c...
