How to use an Arduino to measure speed of rocket I am not very experienced with Arduino and I am trying to learn it. I was wondering what is the easiest and most effective way to calculate speed and log it every second so to say. This would be mounted in a model rocket to see what speeds it can reach. How would I achieve this?

Would it be hard to send over RF to see it in real time?

Thanks in Advance
You can use an accelerometer or a barometre for measure speed and for RF you can use:


Radio NRF24L01
wifi ESP8266
bluetooth HC-06
