Thanks JimboZA.. We are going to have six different stations each with an arduino and a PC. The students are going to write the code for different projects. So far I have had the idea of getting the students to reprogram the blink program for some our lighthouses here in SA. I have ordered some thermistors and LDRs from RABTRON based in Veeriniging, so we can can build our own digital thermometers and a light sensor circuit. We have also had some 300 in 1 kits donated too so we have parts. I just need the ideas really. What have you been using arduino for? Best regards Chris
