[2020]'春节宅家一起造“在家无聊，来场激光打’病毒’
新冠病毒让大家挺闹心的，大家都希望病痛早点消停，武汉早日恢复平静祥和。既然没地方去，不如打打‘病毒’。效果是：当激光枪的激光束打到光敏电阻上，改变了光敏电阻预设的阈值时候，伺服电机会带动‘病毒’倒下，同时ISD录音模块被触发，发出哀嚎声。
ISO1820在连上线，并通电后，直接按REC按键，就可以录最大10秒的录音。按Play可以听录音效果。

==========================================
硬件使用如下：
1.arduino UNO
2.arduino sensor shield
3.9g 伺服
4.光敏电阻
5.ISD1820
6。激光模组
7.微动开关
============================
连线部分有两个，主模块的连线如下
激光枪连线如下

{
if (photocellReading <= 75 && shadeClosed == 0) //if the LDR is showing darkness and the shade isn't closed already
{
myservo.write(0); //then tell the servo to rotate forwards at a steady rate (close shade)
//delay(1000); //2.5 second delay while shade is closing
digitalWrite(PLAY_E,LOW);
}
else if (photocellReading >= 75 && photocellReading <= 150) //if the LDR senses neither new light or new dark (mid-day)
{

谢提醒，已添加2020. 牛，学习中 看起来简单的作品，实际要费不少心思呢{:6_213:} 多谢分享，学习了。 锂电池怎么充电 20060606 发表于 2020-8-5 06:06
锂电池怎么充电
DF商城有锂电池充电板，有3.7v的和7.4v的。
