Hi, i’m making a miniature control panel for something and I have some Allen-Bradley push buttons (with led’s inside) and pilot lights. These are all rated for 24v, and my Arduino Uno’s max is 5v. Can someone point me in the right direction as to how I would go about controlling the pilot light and push button lights with my arduino, while lighting them with the required 24v?
