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…]

RasPiO Pro Hat  - Putting Pi Ports in Perfect Positions for Productive Play

Today I launched the RasPiO Pro Hat on Kickstarter. It’s a Raspberry Pi Hat for GPIO tinkering (it goes perfectly with GPIO Zero). It arranges the GPIO ports in numerical order around a mini-breadboard, which, to my knowledge, has not been done before. It also replaces the RasPiO Breakout Pro (now end of life) because it protects all the ports from over-current and over/under-voltage as well. It should prove a very useful board for GPIO tinkering and education. Have a look at the video and pop on over to the RasPiO Pro Hat campaign page […more…]
