Aside from cool cat feeders, it is possible to find multiple maker projects for controlling garage doors, blind windows, smart locks, tracking cars, control temperature and humidity levels, and so on. However, the security aspect of these devices needs to take some extra attention, starting from the connection between the device and the Cloud infrastructure.
Most microcontrollers today are not powerful enough to handle secure connections, like SSL or TLS, so all the communication between the device and the server is open to attacks, like sniffing values, tacking device credentials, faking values, granting unauthorized access to physical facilities, unlocking doors, and many other possibilities. This way, securing the communications for all the Internet-connected devices should be a priority, especially if they can jeopardize our security or privacy.

An 8×8 dot led matrix is a very interesting device because with proper instructions the individual leds or any group of leds can be programmed to fire. This characteristic, plus the feature that up to eight modules can be daisy chained, forms the basis for a nearly endless series of visual effects. Here we discuss the very basics of working with one MAX7219 dot led matrix module. A simple sketch is provided that creates a ‘smiley’ followed by a simulation of a bouncing ball.

Fuse is a vital protection device for many electronic devices. They simply monitor the current consumed by the circuit/load and in the event of unsafe current flowing through the circuit the fuse will blow itself and thus prevent the load/circuit form getting damaged by that high current. This type of fuse is called a mechanical fuse and there are many types of fuse such as fast blow, slow blow etc, but they suffer from one common draw back. When a fuse is blown it has to be replaced by the consumer/operator to make the device function normal again. This is the reason why many old electronic devices like toaster or electric kettle had a spare fuse provided along with the product.
