NUMATO LAB 4 Channel Solid State Relay Controller Board- (DC Relay)

hi welcome to another tutorial from Robojax in this video I am going to show you how we can use 4 channel solid state relay to control 4 AC load or AC bulb using Arduino. You can get the code for this by clicking at the link which is below the video in the description which will take you to robojax.com/learn/arduino let's get started with this I have to warn you that working with AC is very dangerous and soon as you connect this you connect it to AC i do not touch this module and also do not leave the module on a metallic surface or conductive surface make sure it's on the plastic or non conductive material. many times you need to control AC load and this is the best device to do that because it doesn't have contact and you don't hear a clicks. For that reason solid state relays or prefered the most . the amount of load that they can control is limited and this shown here. Each can cont
