This way I can use conditions to vary the on and off duration and the on and off don't have to be the same duration like blink with out delay. The joystick only allows one direction at a time. On the Uno and other ATMEGA based boards, this occupies 4 bytes. I'll assume one can program their Arduino board. double … On the Arduino Due, doubles have 8-byte (64 bit) precision. I am doing this using else if statements, however, i find this taking up a lot of space. This inplies that you shall not mix doubles and int for this. In some dialects of C, a switch/case can specify ranges, but I'm not sure if the Arduino dialect allows this. The Nano and most Arduino boards today have an LED on digital pin 13 (DP13). If you intend each if statement to be executed, regardless of the whether the prior one(s) did, then yes, they do not require else clauses.. 1 shows the test setup for this series, in this case an Arduino Nano. I'm still not clear why this method worked, but it basically fiddling around with the if / else statements. It states "invalid operands of types 'double' and 'int' to binary operator%". Double precision floating point number. I ended up creating one if / else group for motor A, and another for motor B. On the Uno and other ATMEGA based boards, Double precision floating-point number occupies four bytes. The ms is milli seconds The ms Last is milli seconds last Just like blink without delay. So that saves me a bit more coding. I would suggest to move away from double and witch completely to integers (e.g. uint32_t). 2) a 32 bit float is accurate to more than 5 figures so … Example That is, the double implementation is exactly the same as the float, with no gain in precision. On the Arduino Due, doubles have 8-byte (64 bit) precision. That is, the double implementation is exactly the same as the float, with no gain in precision. Syntax. Double precision floating point number. With regard to the modulo operation: the compiler does not state "invalid operator". Thanks for the replies, it makes more since now. setup is run exactly once at the beginning of your program. Results may vary with other compilers or a non-Nano Arduino board. It is also not in accordance with the idea of programm flow in the Arduino world - the sketches - where you have two methods on the highest (user accessible) level: void setup() and void loop(). I am using compiler Arduino-1.6.3. Some people are like Slinkies. Wouldn't be tough to add a triple-click either, by extending the double-click logic and timekeeping, but that's not a common way to interact with a button. That is, the double implementation is exactly the same as the float, with no gain in precision. On the Uno and other ATMEGA based boards, this occupies 4 bytes. On the Arduino Due, doubles have 8-byte (64 bit) precision. See the code below. 1) in arduino doubles are only 32 bit floats not true 64 bit doubles so the constant casting to double is unnecessary. Fig. I did eventually figure out a solution this afternoon. The bulk of the code just sets up the button and test LEDs and events, the real content being the … double. I have attached a sample of the code to show what I mean.
