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