首先要绘制时钟的的表盘与表盘刻度，表盘用Ellipse函数绘制，表盘的六十个刻度以及时钟的十二个小时刻度用MoveTo和LineTo来绘制。时钟的重绘用Invalidate(false)如果参数是true，擦除背景之后，再重绘，会出现刷屏。定时用SetTimer每一秒调用一次ontime中的Invalidate(false)

大家都知道键盘上几个的事件吧。 今天我就作了一个用上下左右键控制图标的小程序，帮助你理解这几个事件。。很好玩的。-we all know several of the keyboard events. Today I made a key up and down around the small icon control procedures to help you understand these events. . Very fun.

接收单元，我们采用的原理和调频收音机原理一样。图3为接收电路，以专用调频接收模块IC1 TDA7021T为核心，经解调后的音频信号从脚输出，送到IC2 LM386作功率放大，推动耳机发声。三极管BG9018等组成高频放大级，以提高接收灵敏度。调节可调电容器C23可以改变接收频率，使其对准发射机的发射频率。-Receiving unit, we have adopted the principle and the principle of like FM radio. Figure 3 for the receiver circuit to a dedicated IC1 TDA7021T FM receiver module as the core, after demodulation of the audio signal after the output from the feet, to make IC2 LM386 power amplifier, and promote sound headphones. BG9018 triode composed of high-frequency amplification level in order to improve receiver sensitivity. Conditioning adjustable capacitor C23 can change the receiver frequency so that it fired at the transmitter frequency.
