There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra com… ...

PWM pins are generally used in controlling output devices in Arduino projects.To send a PWM value to a PWM-capable pin like the Mega's D9, the easiest and most common way is by using the ...

These lay out the connections that are needed to the Input/Output (I/O) pins on your Arduino board. This can help you learn about the different pins on the Arduino board and how to use them in your ...

I'm taking the liberty of starting a new thread for Arduino projects, as I couldn't find one dedicated to this, and figure that there may be a few people around here who do this sort of thing. If ...

11 Arduino projects that require major hacking skills—or a bit of insanity ... Each sensor can be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno.

Simply connect the Sensor's output to any digital pin on the Arduino and check for a high pulse; if the Arduino reads a high pulse, Gas has been detected; if the Arduino reads a low pulse, no Gas is ...

The schematic diagram of the Arduino Ammeter Project is follows. The schematic diagram shows the connection of the Arduino Uno with 16x2 LCD, ... The data pins D4-D7 are connected to the digital pins ...

This project is a security system for ESP32, allowing users to enter a PIN using a 4x4 membrane keypad. If the PIN is entered correctly, the system displays a message on the LCD screen, and in case of ...

Connect the VRx pin directly to Arduino A0, and the VRy pin directly to Arduino A1. Again, the SW switch connection is not used in this project. sprite-chat-bubble ...

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...
