Do you like this post? A regular project like the PlaneSpotter Color
takes many hours of my free time to develop and maintain. Would you offer me a beer for my hard work if I was your neighbour? Modern technology called teleportation makes it easy to send me a beer. Just click here
. Thank you!
In a later blog post I will describe how I am using a TL-MR3020 router as low-cost wifi shield for my Arduino to transmit sensor data over wifi. In this post I just want to show how you can script a restart of the arduino by powering off the USB port that the Arduino is connected to. In need this because sometimes the arduino does not send anymore data to the ttyUSB0 device. So as a workaround I’m restarting the Arduino from time to time by cron job.
echo 0 > /sys/class/gpio/gpio8/value
echo 1 > /sys/class/gpio/gpio8/value
echo "$(date)" >> /tmp/restart.log
A ridiculous amount of coffee was consumed in the process of building this project. Add some fuel if you'd like to keep me going!
