Arduino Analog I/O Multiplexer. 15 Comments . by: Al Williams. June 9, 2018. Title: ... There are five input pins to the chip which lets you connect one analog pin to any one of 32 analog pins.

The usual method is to use the Arduino’s analog pins to send PWM signals to the module. This lets you mix each color, giving you full control over the RGB LED. Meanwhile, the other (digital) option is ...

The analog voltage for the meter can be generated by PWM. The Arduino PWM outputs have a frequency of about 500Hz which means that the pin cycles from 0 to 5V and back to 0 again 500 times a second. A ...

Adding USB functionality to your Arduino projects used to be a pain, but thankfully, the V-USB project came along and gave your ATMEGA328 the ability to control the USB lines directly and mimic sim… ...

The analog input pins on the two microcontroller boards are also somewhat similar. They both have 10-bit resolutions that can read values of up to 1024, and their A4 and A5 pins both double as SDA ...
