I am making a led panel using led strips. Each of the two led strips are 5M long containing 300 LED SMD Striplights. I have cut each of the 2 strips into many small strips of lengths of about 38 cm and connected them in parallel i.e there is a singe pair of terminals for all the strips.I have a 12V,5A power supply. I had tried to drive the panel using Arduino Mega in combination with a MOSFET as is it is commonly done for a single led strip but I am unable to make it work. Can anybody please help me out?
Other components being used are - PIR sensor , RTC module
