This repository details how to create a PCF8574A based I2C LCD controller module PCB, ascociated libraries and test code. The module solders directly on to the back of an HD44780 LCD and differs from ...

The Waveshare 1.69-inch IPS touch LCD is a 1.69-inch rounded display with 240×280 resolution and a 262K color range. The display driver (ST7789V2) and touch controller (CST816T) are integrated ...

Already back 2019 I have developed a working I2C slave implementation where master can read/write to address memory. BTW, this is still not working in Espressif IDE examples or Arduino Wire examples.

The 16-channel 12-bit PWM/Servo Driver, PCA9685, is an ideal module for precise control of multiple PWM outputs that are commonly used to control servos, LEDs, and other devices in applications such ...

I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

The MPU6050 module has a total of 8 pins, of which at least 4 pins are necessary for the interfacing. VCC provides power for the module. Connect to the 5V pin of the Arduino. GND Ground is connected ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...
