  • 2. It should go without saying. If you’re playing with electricity make sure youknow what you’re doing. Electronics enthusiasts and hobbyists will be quick totell you of the care you need to exercise, especially if dealing with relays and arelay board. http://proto-pic.co.uk
  • 3. Essentially, relays act as switches between low currents and voltages and high currentsand voltages. A relay board, or if you’re working on an Arduino project, a relay shield, arevital pieces of equipment. But you must use them wisely. They’re there to protect youwhen switching voltages so make sure you give them the respect they deserve. http://proto-pic.co.uk
  • 4. Aduino? What’s that? It’s an extremely popular prototyping platform.Arduino boards themselves are programmable micro-controllers. You canalso attach modules to them in order to perform various different functions. http://proto-pic.co.uk
  • 5. It’s possible to control certain processes with just yourlittle micro-controller and bit of programming.However, this is where relays and a relay board are needed. http://proto-pic.co.uk
  • 6. Let’s say you want to make a lamp blink on an off. Using a relay boardyou can use relays as switches. The shield will safely manage theincrease in voltage needed by your controller to power the lamp. http://proto-pic.co.uk
  • 7. Remember the fundamental principle here: we’re tryingto get an electronic device that only uses a small amount ofpower to control a much larger amount of juice. http://proto-pic.co.uk
  • 8. OK, but what other examples are there of relays working in practice?Well, do you have night security lighting? You know, the type that’scontrolled by a sensor reactive to light or movement? http://proto-pic.co.uk
  • 9. It’ll utilise a relay. In practical terms, the relay interacts with a smallbattery-powered light dependent resistor to control a mains powered light.As previously discussed, using Arduino technology it’s possible toassemble a similar set-up to perform cool tasks. http://proto-pic.co.uk
  • 10. As relay boards are crucial to many devices, it’s also essential topurchase equipment you can rely on. If your project frequently utilisesswitching mechanisms you need components that will work again andagain. http://proto-pic.co.uk
