pow() can be used to raise a number to a fractional power. This is useful for generating exponential mapping of values or curves.Syntax pow(base, exponent)Parameter Values base: the number. Allowed data types:
都还是从 UNO板子上开始玩，而这些板子的共性，就是都是用了 DIP（直插）28 脚封转的主芯片。
{ OSCCAL = 240; // Overclocks the MCU to around 30 MHz, set lower if this causes instability, raise if you can/want ADCSRA &= ~(bit (ADPS0) | bit (ADPS1) | bit (ADPS2)); // clear ADC prescaler bits ADCSRA |= bit (ADPS2); // sets ADC clock in excess of 10kHz ADCSRA...
37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
radio.setDataRate(RF24_1MBPS); // Raise the data rate to reduce transmission distance and increase lossiness radio.setAutoAck(1); // Ensure autoACK is enabled radio.setRetries(2, 15); // Optionally, increase the delay between retries. Want the number of auto-retries as high as possible...

Raise or lower P column PID values for Pitch and Roll. If the drone wobbles fast, lower the value. If it wobbles slowly, raise the value. Keep adjusting incrementally until it’s flying stable. Add a 10 microfarad capacitor to power inputs of the NRF24L01 if there’s no radio connection...
void write(uint8_t v, uint8_t power = 0); void write_bytes(const uint8_t *buf, uint16_t count, bool power = 0); Write a byte, and leave power applied to the 1 wire bus. The writing code uses the active drivers to raise the pin high, if you need power after the write (...
We now need to see how far down to mount the drive axle to make the frame level. So raise the rear of the frame up until the top of the frame is level with the ground (use your level). Now measure the distance from the top-rear of the frame to the ground, this is the frame ...
