首先,需要增加从气象站到室内接收器的无线数据传输功能,去掉了SD卡模块,换成Arduino Uno接口扩展板。 这样做的主要原因是为了节省空间,接口扩展版完全兼容Arduino Uno,因此无需使用导线进行连接。气象站支架也进行了重新设计。之前的支架太低,而且不稳,所以我又做了一个新的支架(更高而且更稳)。对于直接安装到气象...

Arduino Unois a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everyth...
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can ...

Arduino Uno是一款基于ATmega328的微控制器板。它有14个数字输入/输出引脚(其中6个可用作PWM输出)、6个模拟输入、1个16 MHz陶瓷谐振器、1个USB连接、1个电源插座、1个ICSP头和1个复位按钮。它包含了支持微控制器所需的一切;只需通过USB电缆将其连至计算机或者通过AC-DC适配器或电池为其供电即可开始。A000066查...
The Arduino Uno board can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-pos...
float current = voltage / R_LOAD; joules += voltage * current; float wattHours = (joules / 3600.0) * 1000.0; And here how it work: We need to measure voltage in circuit. This is why, in first step, we read 10bit A/D converter and scale output to 5V. Why 5V? Arduino Uno works...

However, a jumper on the board enables voltage translation to 5V at the I/O pins. This provides support for 5V Uno shields and is the default behavior. By switching the jumper position, the voltage translation can be disabled to provide 3.3V operation at the I/O pins.Of course, the ...
