Many of the sensors originally developed for the Arduino do not offer a digital interface and can only be read out analog. The problem is that the Raspberry Pi with its GPIOs cannot read out any analog signals, which is why you need an analog-digital converter (ADC) like the MCP3008. This means that up to […]
Read MoreThanks to the inexpensive Raspberry Pi Zero, Internet of Things (IoT) projects will continue to grow. One disadvantage which the Zero (not W) and A+ models have is the lack of Ethernet connectivity. That would not be a problem, if not just a single (micro) USB port onboard. In order to connect these models with the […]
Read MoreIn addition to some wireless connections such as 433Mhz, infrared and NFC, Bluetooth is probably the most common and popular mode of data transmission between smartphones, which is why the Raspberry Pi Bluetooth data transfer is interesting. Meanwhile, pretty much all devices support Bluetooth and can not only be paired with it but of course, […]
Read MoreToday saw the launch of the Raspberry Pi 4. Changes over the previous model include more memory options, a faster quad-core CPU, support for dual displays at up to 4K resolution, Gigabit Ethernet, USB3.0, wireless LAN, Bluetooth 5.0, and USB-C power. [embedded content] Specifications 1.5GHz 64-bit quad-core ARM Cortex-A72 CPU ( ARM v8, BCM2837) 1GB, 2GB or 4GB […]
Read MoreAnyone who has ever thought of a car PC has certainly dealt with radio reception. Now there are not too many possibilities to use the Pi as an FM receiver, but one is the Si4703 module, which is used here. In a previous tutorial, I have already shown how to use the Raspberry Pi as […]
