It also has an integrated battery charger. The Arduino needs to be powered by a rechargeable Lithium Polymer battery like 3.7 Volts. - Control LEDs: I believe I can get by with two white 3mm LEDs. I will install fibre-optics to transfer the light from the LEDs to various lenses on the fi...
Hi, I need some recommendation to eliminate the shadows from the cabinet pulls in the laundry room. The two LED lights in the ceiling have 930 lumens each at 3500K. Can we adjust the LEDs to get rid of the shadows? Also the other question is where we should set the undercounter light in the upper cabinets in the kitchen, towards the back wall or to the front of the cabinets or mid way? The cabinets are 24" deep, not the traditional 15-18". Thanks
