We took our popular 1.8" TFT breakout board and remixed it into an Arduino shield complete with microSD card slot and a 5-way joystick navigation switch and three selection buttons! Since the display uses only 4 pins to communicate and has its own pixel-addressable... Add to Cart, ...
Such a small current can easily switch on a transistor, and the transistor could in turn switch on a motor, relay (this is another switch controlled by a small current, except it is mechanical), a fan, a larger LED, among countless other devices....
