Week 4 – ShrimpingIT Maker Club
Good things – I ordered the PIR sensors, got plenty of LEDs, got 10 extra breadboards to give more space, tried and tested (and fixed) all 10 Shrimps 🙂
But…the PIR sensors didn’t arrive in time (China sourcing is cheap but slow 🙁 ), decided to get club members to install S4A (Scratch 4 Arduino) on the laptops and upload the S4AFirmware to their shrimps – that took lot longer than it should/expected so we just ended up with 15 mins of actually programming our Shrimps but they all liked using a Scratch type interface and they switched their LEDs off and on and connected a switch to an input and saw that the S4A monitor changed value (they did query the words true/false).
As I only had one PIR sensor, we plugged that one in instead of the switch and we had a bit of fun in seeing if anyone could get near the Shrimp without setting it off.
Hopefully – next week, they will all be able to code up a simple alarm using S4A and maybe we can get around to the principle of an entry/exit delay
