This LCD and Keypad Shield gives you a handy 16-character by 2-line display, 5 buttons and a controllable backlight, plug it straight in on top of your Arduino board or other project shields. The display is set behind the shield for a low profile fitment and nice look and we've included panel mounting screw holes in the corners.
This shield allows you to use a computer power supply (or other power source) to use your Arduino to switch high current. With RFP30N06LE MOSFETS, you can easily control a lot of current directly from your Arduino.
Ethernet Shields generally come with stackable headers fitted, but the big problem is that because the RJ45 jack is so high it's not possible to stack another shield on top without jamming it on at a strange angle. So we fixed the problem: we designed a special prototyping shield that's short enough to fit onto an Ethernet Shield with clearance behind the Ethernet jack.
315MHz and 433MHz wireless connections are very commonly used by consumer electronics including weather stations, home automation remote controls, power consumption meters, car alarms, and also many DIY projects.
The Terminal Shield breaks out all the Arduino headers to handy screw terminals, making it really easy to connect external wires without using a soldering iron. Ideal for quick experiments or for robust connections!
