Muchas veces hemos visto estos sistemas en industrias , centros comerciales etc. . cuando se va la energía eléctrica las luces de emergencia se activan pero cuando hay energía eléctrica solo sirven para carga...
I decided to split my ESP32 Guitar Shield project into smaller modules, which can be reused in other projects. This is the AD/DA part AD/DA Cookie This square-inch-sized PCB is a high quality audio codec board featuring an AKM AK4556 i.e. an analog to...
SUPPLIES: The LED’s we choose are REFOND RF-RURA30TS-CE, because of high viewing angle (120°), low profile (it was important for us to keep the PCB as low and light as possible), and high luminosity (542...1192mcd), the parameters of used diodes...

Primeramente diseñaremos en diagrama esquemático y también simularemos el proyecto en el software PROTEUS Vemos dos circuitos ya que para este proyecto hemos desarrollado para los transistores BJT tanto para PNP y NPN. Veremos el...
Este sistema esta basado en el ARRANQUE DIRECTO de motores de CA en electricidad INDUSTRIAL ya que ahí veremos este tipo de arranques mediante contactores y pulsadores industriales por ello ha decidido realizar un circuito que me permita controlar...
Some time ago i was thinking of how to shrink LED blinkies even more. The first obvious step is to move from 3mm LEDs to SMD. But than there is still this tiny gap between the LEDs which likes to short-circuit with a solder bridge when soldering. Could...
I started from [cy384]'s excellent repository for an Arduino Pro Micro based adapter for a PPK. Unfortunately, I found that the pinout on my keyboard was different and had a much finer contact pitch (0.8mm!). I ended up needing to fabricate a small PCB...
FeaturesThe EmojiPad is a USB Keypad in the form of a soldering kit. To allow a beginner to assemble the kit it has the following features:100% Through-Hole ConstructionNo SMD Soldering Skills Needed!Easy to read instructions for assembling the PCBWell...

I got involved with Arduino during my Covida in an effort to help my friend with a Bluetooth LE remote like one of those presentation gizmos to move between slides. At that time, I never even thought of putting two chips on a PCB by myself, but I was...
Whenever we have to use video output in any IoT or robotics project then Esp32-Cam module comes into mind. It is the one which can fulfil all the needs and has comparatively low price than other modules available. The good this is we can use SD card...
