what is relay. What is the purpose of relay in ardduino. In this video we are going to discuss about relays. Relays are used when we have to control a device for example a high volt motor which cannot be directly controlled by arduino, because arduino only gives 5V output. So we use relays. We can also use relays with our electrical appliances to control our tube lights fans etc.
