Boards including the Uno, Duemilanove, Diecimila, Nano, and Mega have a chip to convert the hardware serial port on the Arduino chip to Universal Serial Bus (USB) for connection to the hardware serial port. Other boards, such as the Mini, Pro, Pro Mini, Boarduino, Sanguino, and Modern ...

1. Current Arrays values: This can be done by connecting a multimeter in series with the battery. Press the up button and measure the current, the current values are the elements of the array. 2. Vcc: You use a multimeter to measure the voltage at the Arduino 5V pin. In my case it...
To convert one into the other, you must reverse the byte/nibble positions and then reverse all bit positions of each byte/nibble or write it as one binary string and reverse/mirror it. Example: 0xCB 34 01 02 0x20 10 43 BC after nibble reverse 0x40 80 2C D3 after bit reverse of ...
Repetier-Firmware uses a higher resolution for input and temperature and these factors convert old tables you may have into the needed value range for Repetier-Firmware. If you don’t have a matching table, you have to compute one.Looking into the datasheet gives characteristic curve 8404 for ...
byte anode[8];//byte to write to the anode shift register, 8 of them, shifting the ON level in each byte in the array//This is how the brightness for every LED is stored, //Each LED only needs a 'bit' to know if it should be ON or OFF, so 64 Bytes gives you 512 bits= ...

To fix this, use a logic shifter chip that converts between 3.3V and 5V logic. This library has been successfully tested on many boards including: ESP32; STM32; Mega 2560; DUE; ATmega328 and Atmega32u4 based boards; ATtiny85, Raspberry Pi Pico (RP2040) and more. See Boards where this...
