While playing with the raspberry pi camera I found it hard to know if the camera was working or trying to tweak settings. I was using raspivid -f to preview the video. This was limited with being open for 5 seconds ( can be adjusted using the -t flag and passing it seconds in milliseconds ). The solution was to open a streaming video from the raspberry pi and view it on my host ( mac ).
Connecting to Raspberry pi 2, 3 and zero to a RFID sensor, This summarizes my experiences using the tutorial found on Sunfounder.
The Internet of Things is still a new tech kid on the block. People are innovating and achieving the impossible. It can be tough to quickly make sales, also something you create might not have customers. This could lead to a problem. You might waste a lot of time and as a result, depletion of funds can happen. Worst case scenario would be if customers do not like the product. There is a way of tackling both ends of this problem, crowdfunding. Crowdfunding has enabled innovators to follow their heart and seek funding from people. The customers get to use a prototype of the product and the innovator gets the return. Here are some of the best crowdfunded projects in the world of Internet of things (IoT):
Its Official, they were whispering and speculating about it. It enthused you earlier to know more but it is time for you to delve deep in the world of Internet of Things or IoT. With a constant increase in the demand for IoT professionals, it is time you graduate to the more serious scheme of things. So, get your Notepads out (Online or Offline, whatever suits you) and make notes of what you can do to learn IoT and not be ‘just’ aware it.
People often ask me what is possible with the power of the raspberry pi. I’m have a tendency to buy numerous microcontrollers / cheap standalone controllers, just to see how they work and if they could prove more useful to me than the raspberry pi. The release of the Pi Zero for $5 pretty much put the nail in the coffin when it comes to IoT ( Internet of Things ) work for prototyping.
