Details

In this 5-part presentation, you will learn how to work with relays and connect large loads to your Arduino. Modules

Using the TIP122 transistor to control an LED strip (http://bit.ly/2hc6lWI) (7:46) In this lecture, you will learn how to use a TIP122 Darlington transistor to drive a 12V LED strip.

Relays Part 1: Introduction (http://bit.ly/2hGggVa) (4:57) Introduction to relays

Relays Part 2: How NOT to control a relay (15:20) Part 2 demonstrates how to quickly (but incorrectly) wire a 5V relay to the Arduino

Relays Part 3: Connect a 12V relay component calculations (http://bit.ly/2i04iom)(10:05) In part 3 you will learn how to calculate the values for the components that are required for the correct wiring of a 12V relay to the Arduino.

Relays Part 4: Connect a 12V relay connections (http://bit.ly/2hciZoC) (7:50) In Part 4, you will take the component values calculated in Part 3 and complete the wiring of the 12V relay to the Arduino

Relays Part 5: Relay shields (http://bit.ly/2gWeJMi) (4:20) In part 5 you will learn about a couple of relay shields that are good alternatives to manually wiring relays to the Arduino. Parts Needed
