Raspberry Pi 3 model B launches today - 64-bit quad A53 1.2 GHz BCM2837

Raspberry Pi 3 model B launch is today’s big news. The new Pi sports a 64-bit quad-core ARM Cortex A53 CPU with VideoCore IV GPU packaged into the new BCM2837 chip. This 1.2GHz CPU offers ~50% speed improvement over the Pi 2’s BCM2836. Video Overview Pretty much all the information and impressions I have of the Raspberry Pi 3 model B are in this short video… …but if you prefer to read, it’s all here too… Now With Built-in WiFi & Bluetooth The other major news is that the Raspberry Pi 3B now has built-in […more…]

Using MCP3008 to measure temperature with GPIO Zero and RasPiO Pro Hat

In the previous article I showed you the GPIO Zero Experimenter’s Kit I put together to go with the RasPiO® Pro Hat. Today I’m going to give a quick overview of how to use the MCP3008 analogue to digital converter to read the TMP-36 temperature sensor. This gives us a temperature reading (in °C) that we can use to make “decisions” in our Python program. In our case, we’re going to switch on a red LED when the temperature is 24 °C or greater. But there are all sorts of other things you could do, […more…]
