This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

This is an Arduino program to make a 6 bit DAC using an R2R ladder connected to the corresponding pins on the Arduino.. The code is a slight modified version of a previously existing one provided by ...

Servo motors and are constructed out of basic DC motors, by adding: • gear reduction • a position sensor for the motor shaft • an electronic circuit that controls the motor's operation Typically, a ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some… ...

Analog Link. It is also possible to read the amount of moisture present in the soil (for judging whether the soil is wet or dry) by linking the analog output (AO) of the module, to one analog input ...

Becky Stern and the Digi-Key YouTube channel have created beginners overview video of Arduino inputs and outputs. Providing a 10 minute overview of what you can use the range of microcontroller ...

As stated, The joystick can be moved in two dimensions typically represent the X and Y. The X position is read from analog pin A0 and the Y position is read from analog pin A1. In the Arduino sketch, ...

Whereas a typical scale would then simply show the resulting number on an LCD display, [Mirko] decided to use a moving coil meter driven by the Arduino’s analog output.
