I am using Arduino Micro 5V , When i program Digital PIN x to swich Relay , It does not work the electricity does nbot pass through, The setup is correct.
I tested with Meter and it shows around 4.1 V flowing.
Tested same setup with Arduino UNO 5V , and VCC 5V worked fine , with 4.9 V flowing.
I this it has something to do with low V in Micro? What can be the solution to make it work.
Though relay shows light toggle but Electricity does not pass.
