Recently want to use Raspberry Pi control model of the ESC, so studied the next PWM, seemingly control the ESC is troublesome, because the ESC needs to send a few specific signals to start, and then to enter the control mode, today first understand PWM, slowly toss. The following program pro-test is available, I use th
program, we can see the following output information when operating the Sony PS2 button:

This module can be bought on the internet and a few dollars cheaper.The following is a Raspberry Pi B + version of Gpio PIN definition:USB to TTL used to 4 pins for 3.3V, GND, TXD, RXD (note official online said must use 3.3V)The pin used for Raspberry Pi is 1 (3.3V), (GND)

I found that this script occasionally skips 1 second, probably because the date command is not exactly printed every second, so sometimes the output time is not used.
When I run this script, I log on to a Raspberry Pi and enter "sudo reboot" to restart the device. This script is running all the time.

In my previous article, I talked about how to build a high-availability system: Two Raspberry Pi deploy the GlusterFS cluster file system, and it becomes a fault-tolerant file server. In this article, we will build another Fault-Tolerant Service Based on this high-availability system: Build a simple Web server cluster.
