On the 3G shield, by default the power pin is on D8 and reset pin is on D9. Make it HIGH then it works. if you want to play this 3G shield using SoftwareSerial on Arduino, Try this code: /* Change UART control ports from Tx0 / Rx1 to Tx2 / Rx3 using…
This is an old arduino 3G module bought half years ago. Its wiki: http://wiki.iteadstudio.com/ITEAD_3G_Shield Its mall: http://imall.itead.cc/itead-3g-shield.html But as you can see that, the download link does not exist anymore. But after googling a…
About this project This project was developed after I had to find out that controlling my RGB ambient light with the normal infrared remote control was complicated and not reliable. Within a few months I build this solution that enabled controlling m…
Arduino 背景可以参考官方网站www.arduino.cc 先看一个最简单的示例程序: 打开 Arduino IDE , 选择菜单:文件 -> 示例 -> 01.Basics -> Blink /* Blink Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */ // Pin 13 has an LE…
