This mini-project demonstrates the use of a resistor ladder (https://en.wikipedia.org/wiki/Resistor_ladder) as a DAC (Digital to Analog Converter). The program works ...

Arduinoを用いて、デジタル制御で抵抗値を制御する方法を思いついたので、記録する。 目的 抵抗値のデジタル制御は、一般的にデジタルポテンションメータICを使用する。デジタルポテンションメータICは安くて、小型のため、簡単に使うことができる。

Messing around with Arduino can lead to some fun projects — like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...

To provide a cost-effective means of implementing analogue-to-digital and digital-to-analogue signal conversions, TT electronics BI Technologies has released a series of 8-bit and 10-bit R2R resistor ...

This project shows how to connect five push buttons to a single ADC pin on an ESP32 using a simple resistor ladder (voltage divider). This is a test for a component for a larger project. Five 2.2 kΩ ...

Abstract: This paper presents a low-power programmable gain amplifier (PGA) with reused current and resistor-ladder for zero-IF/low-IF short-range ISM-band receivers. The proposed techniques benefit ...
