Hi i am study A level dt at school and need some help. I need to make a circuit that will light up LED's when it is dark. The circuit must be cheap and run off a 12v and under power supply. Also i will need to know where to get the parts from thanks
At a quick guess the OP is in the UK, so I guess that you would not be familiar with "A level" AG. A level is a series of exams generally taken at the age of 17 or so, prior to leaving (high) school and maybe going on to university or w.h.y. At another quick guess, DT is Design and Technology.I will not address the subject of the project this time, but I will say to Jake (if he re-appears), please make your posts a bit clearer and less ambiguous, this is an international forum and many of the experts here will not be familiar with UK school culture. Come to think of it most of us oldies in the UK are not familiar either! Also, it is a good idea to fill in your location in the registration area, this often helps in sorting problems. OK, judging from the time the original post was made it may have been done on a school computer where the party line would be to never reveal where you are lest the boogie man comes and gets you. However putting UK or the nearest major town/city cant hurt anyone.JimB
Hi guys sorry about that yes im from the UK and i am still at school. Basically i just want to make a circuit that will turn on LED's when it is dark and it will run off a small 9v battery or some AA's. I would also like to put a variable resistor in the circuit to control how dark it needs to be for the LED's to come on. Would this be hard? as i say im still at school so could u explain as simply as possible as i am new to electronics. Thanks
