To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ... It is more like a 32-position switch that connects a single pin out of 32 to one ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup ... and 1,023 when read by the analog pin of the Arduino. This number sends ...

Among all the Arduino boards ... as normal digital pins that can switch a component either fully on or fully off, they can also be used to generate simulated analog values through a technique ...

switch. The decoding is implemented using the Arduino Uno and requires only two pins (OCRA and INT0), leaving all of the other pins free for alternate functions. The theory, which is the basis for ...

Conversely, the comparator output and the connection to the Arduino’s analog ... to use 8 output bits and an R2R network to generate an output voltage quickly, but that eats up a lot of pins.

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...
