前回はアナログ回路で簡易ユニットを制作したが、今回はいよいよ Arduino をメインに据えた「疑似タコインジゲーター」を作ってみることにした。 とはいえ、まだまだ電子工作はヒヨッ子で ...
さて、前回はラズパイやArduinoをお迎えしたという話をしたところですが、今回はそもそもとして「回路」についてもある程度の知識を身に着けておくのも大事かなと思い制作した「アナログ ...
In this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...
采用开关型电源，使用4引脚(DIP-8封装)单片集成块5L0165R制作的旅行充电电源适配器具有电路简洁、体积小等特点。其额定输入 ...
We build the Arduino based Multi-house Water Pump Control System. Here we are going to explain step-by-step, how you can make your own Water Pump Controller. But before that, we need to understand why ...
IoT and home automation have come a long way since they first gained popularity in 2014, thanks to the debut of a game-changing IC called the ESP8266 by espressif systems. Today we know it as the ...
I picked up some pulse width modulation to voltage converter modules. You’ve seen these before under a variety of names. They look amazing for the price, but there are a few little things you might ...
I have selected ESP8266(ESP-01) Chip which is the smallest microcontroller that comes with default wifi connectivity and also we can design a small PCB using this ESP8266 Chip. The next main component ...
A tachometer measures the rotation speed of motors and other machinery. There are various types of tachometers. Described here is a digital non-contact type tachometer using a proximity sensor. The ...
