Hello everyone :) I am new to easyEDA and i am trying to draw schematic of the project above, which i will need to convert to PCB and also implement in real life. Of course i have lots of questions, which i would be appreciated if any of you can answer: 1) I couldnt find 12V DC battery, am i missing it? 2) In the project above, there is a 15 ohm 2 watt resistor, i couldn't find it so, i used Metal Oxide Film Resistor instead. Can it cause any problems for me? 3) I couldn't find 0.15 ohm 1 watt resistor, all i could find was a 0.15 ohm resistor without any info about watt. Am i missing it too? Or should i just use 0.15 ohm resistor regardless of watt? 4) MBR2045 in above circuit has only 2 pins. But in easyEDA i couldn't find it so i put the MBR2045FCT, which has 3 pins. Should i only connect one of them or should i connect the 2 pins together like in below schematic? 5) In the above project it warns about 1W White LED and i tried to find the most suitable LED. I could find the one in below, its power dissipation is 0.9W. Is this LED appropriate? My easyEDA schematic, for now:
