or revert to NORMAL if already in HIGH. If the sensors report values that are higher than 1.1 times the average values, and this has happened more than 30 times the last few milliseconds, it will enter HIGH mode. TODO: Not very well written, remove hardcoded values, and make it more re...
Adafruit_NeoPixel strip = Adafruit_NeoPixel(64, PIN, NEO_GRB + NEO_KHZ800); // IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across // pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input // and minimize distance between Arduino and first pixel...

If you have used an other software, that also writes to the EEPROM, your data gets corrupted and you should make sure, the values are reinitialized. From version 0.80 onwards the firmware stores a checksum, so most corruptions are detected automatically....
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= ...
If you do need to work with a String class, you need to make an array of characters, as shown here: char name[5] = {'j', 'o', 's', 'h', 0}; or char name[] = "josh"; If you need to, for example, store multiple strings in an array, you can create an array with ...
An array named "motors" is defined to store the mapping of actuators. Each element of the array represents an actuator and contains information such as the actuator ID, pin number, direction, middle position, elevation, and side. Walking Steps: ...
I prepared some diagrams to make myself clear. The following points are referring to the images. On the first image we can see what I mean withcontinuous acquisition. We define a buffer that will store the data, in my case an array with 1280 slots, then we start to continuously read th...
