A very quick test using the Arduino Graph example yields a stream of readings from a pin, and aggregating several thousand of them into a spreadsheet shows an extremely narrow distribution ...

// Display: SDA pin -> Arduino Analog 4 or the dedicated SDA pin // SCL pin -> Arduino Analog 5 or the dedicated SCL pin // Arduino Leonardo: // Display: SDA pin -> Arduino Digital 2 or the dedicated ...

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

The use of this book as a jumping off point could have used a little help. For example, the LED bar graph uses 10 pins on the Arduino, which is great for an introductory example.

Arduino is programmed to read the analog input at its A1 pin and print the readings to the serial port. These EMG readings can be set and monitored as numbers, ranging from 0 to 1023, on Arduino IDE’s ...

For example, writing to pin 8 using an Arduino function would be “digitalWrite(8,HIGH)”. However, to write to pin 8 by coding directly to the microcontroller, you would set bit 0 of the PORT B ...
