Question 8

I've been trying to follow this example code for interfacing my atmega328P with Mpu6050: https://www.instructables.com/Accelerometer-MPU-6050-Communication-With-AVR-MCU/ And was wondering a couple of ...

Question 9

I have this long array of 64 values going from 0 to 15, values which only cost 8 bits, for a pulse width modulation. So I made a test to see its cost in space, commenting one of the two arrays. const ...

Question 10

My progress so far: #include <SoftwareSerial.h> SoftwareSerial ttySerial(10, 11); // RX, TX byte buffer; void setup() { // Open serial communications and wait for port to open: Serial....

Question 11

I'm trying to use the RF24 library for wireless communication. However, it appeared that this library does not have "help" option. There was a keywords file but it did not explain what it does. I ...

Question 12

You can extract the low-order (rightmost) byte of a variable or the high-order (leftmost) byte of a word with the functions lowByte() and highByte() respectively (the quotes are from the Arduino ...

Question 13

I am using an infrared sensor called OTI301. In its data sheet it says that in order to obtain object temperature and ambient temperature values I need to extract the binary information from the ...

Question 14

I am trying to convert a char[12] array that contains a Mac Address into a byte[6] in order to use within the Ethernet.begin method. I have tried various methods from online, but had little success to ...

Question 15

I have created a byte for 16x2 LCD. It is basically a custom character which I will have to change later. byte char[8]{ B10000, B01000, B00100, B00010, B00001, B11000, B11100 }; I want to edit ...
