[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ...

This library is used in order to abstract away a few of the details to do with analog multiplexing and demultiplexing. It assumes the following: The multiplexer is analog and is compatible with the ...

The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

Create a voltage divider circuit with the flex sensor. In my testing, I used a 44k Ohm resistor. Power can be provided to the circuit from the built-in 5v pin. This guide has a handy wiring diagram, ...

When it comes to educational electronic projects, it’s hard to go past building a clock. You learn tons about everything from circuit concepts and assembly skills to insights about the very nature of ...

This short article describes a simple circuit capable to convert a TTL/CMOS PMW signal to an analog signal. The circuit can be used as an extension shield for Arduino with a simple MCU or with ...

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 ...

I have started this joystick controller experiment inspired by the need of a simple DIY joystick which could deliver greater flexibility in the possible designs. Hardware component basis is very ...
