The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386.

This project is a simple counter using an Arduino UNO, a 20x4 I2C LCD display, and two push buttons. The counter value is displayed on the LCD, and the buttons allow users to increment or decrement ...

Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems that external pull-up resistors for I2C lines are ...

LSI COMPUTER SYSTEMS LS7366RSH shield development kit highlights the LS7366R IC, a 32-bit CMOS Counter with direct interface for quadrature clocks from. ... 6-Channel 32-Bit quadrature counter dev ...

Geiger counter, it's a word that most people have heard about. I'm sure everyone has seen at least one piece of media featuring the clicking box with a little dial that only tells you when you're ...

This Arduino library is designed for the AIT1001 non-contact infrared temperature sensor. It simplifies the process of reading both ambient and object temperature, allowing for seamless integration ...
