Hey all, recently I've been working with a robotics club at my school and we purchased an arduino uno. We'd been hearing how it was a great learning experience so we decided to go ahead and buy it. So when we finally received it, we were so happy and excited to get going with it. The first thing we did is unbox it, create a circuit with our lcd (we bought a kit from makershed) and we upload the hello world liquid crystal sketch... To our suprise nothing appeared on the screen but we realized that the potentiometer in the circuit controlled how dim the lcd was. I've had 4 people build the circuit all with the same result. Is it the arduino? The sketch? The microcontroller?
Please help and I will be happy to provide any other info such as the code itself...
Thank you very much,
