How do you reduce 6 volts to 4.5 volts? Answered
I am working on a toy truck that will play music, have headlights that will light and a gear system that will lift the truck up and down when a switch is pressed. The music (took from a stuffed keychain pig) and lighted headlights (Blue LED) work using 4.5 volts. My gear system use to use 4.5 volts to lift the truck, but now it won't do it. In order to lift the truck I have to increase the voltage power to 6 volts. If I increase the power of the gear system to 6 volts or more then it will fry my music and lights (however, I can make adjustments to the LEDs with resistors). The higher the volts are for the gear system, the easier it is to lift the truck. Maximum volts for the system are 12 volts. I know lifting the truck puts a strain on the system but the more power I give it; the better it can lift the truck. My goal is to use one power source and one switch. I thought I could use to different power sources (6 v and 4.5 v) and connect it to one switch, but I think it will fry of my music and lights. My question is: How do I reduce 6 volts to 4.5 volts, using 6 volts as my main source and connect everything to one switch? If I can get this figured out then this will help me with future project, where I need to use voltage reduction (or is it called voltage regulator). My knowledge of electronics is very low or enough to get me in trouble, which it has done. I am familiar with a few basic electronic terms and formulas. I will except and appreciate any help, ideas, diagrams, etc. Please use layman terms.
