3W RGB LED drivers - 3 high current MOSFETs will let you connect to 3W RGB LED for powerful eye-blasting glory

all the on board circuitry to output RCA signal

This inverter has a little microphone and will light the connected EL according to the surrounding audio volume

you will not only learn programming knowledge such as variables and functions

USB Host Switching Cable - Mini Mechanical KVM CANBUS In this resistance sensorThis ordinary looking USB cable actually has a surprise trick up its rubber sleeve. It's kinda like a 'miniature KVM' (minus the video part, and only one USB port). The mechanical switch connects to the D+ and D pins on the two USB A host ports. So when you switch back and forth, the USB peripheral connects from one to the other. So, suppose you're working with Raspberry Pi, a USB Key, and a laptop. You can use this handy cable to switch the USB key
