Program for a custom made "Mirror-o-Matic" machine controlling two motors (turntable and ExtenderWheel) with and arduino (nano) and pwm. I2C for input devices like the 4x4 keypad and the 16x2 lcd ...

Arduinoプログラミングに挑戦しつつ、モジュラーシンセサイザー デジタルノイズ&ハイハットモジュールを自作したので、その備忘録。 背景 コードの書けないシステムエンジニア脱却のために始めたプログラミングの13作品目。前回、Arduinoのレジスタを直接 ...

Let's jump on to learn about key features of the L298N Motor Driver, which plays a huge role in controlling heavy-load DC motors. It is based on a Dual H-Bridge design for controlling two DC motors ...

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 ...

ESP32 は Wi-Fi/Bluetooth 搭載 MCU として有名ですが、実は 産業用レベルのモーター制御が可能な「MCPWM」ユニットを備えています。 通常の LED 向け PWM（LEDC）ではなく、DC モーター・ステッピングモーター・BLDC を正確に制御するための専用 PWM です。 本記事では ...

Library to control a PCA9685 16-channel PWM driver module from an Arduino board. Licensed under the copy-left GNU GPL v3 license. Created by Kasper Skårhøj, August 3rd, 2012. Forked by Vitska, June ...

This short article describes a simple circuit capable to convert a TTL/CMOS PMW signal to an analog signal. The circuit can be used as an extension shield for Arduino with a simple MCU or with ...

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 ...
