Hi, I have been experimenting turning on heavy loads with arduino using transistors and relays with varying success.
The main problem I have is the in rush of current to start a high power HID spotlight is enough to drain all power from microcontrollers and other power supplies, causing them to reset or damaging them.
I would like to know what I can do to keep the steady power to my micros and power supplies while the heavy load starts up.
do people use batteries to keep micros alive during this process ?or is there a circuit that i can implement to get the job done?
I have attached a basic schematic of my project.
thanks
