Gikfun MT3608 DC-DC Step Up Power Apply Module Booster Power Module 2A for Arduino EK1762

My name is Ahmad Shamshiri and I am presenting this tutorial from Canada. Hi, welcome to Robojax. inn this video we are going to test this booster converter this is a 3 ampere booster converter that can get 3.3 volts up to 27 volts output so you can get 3 volts 4 5 6 whatever and then adjust whatever higher voltage that you want. so it boosts it up. but this is the setup now I have connected as you can see here five point seven volts is coming and entering and these are the wires so this is connected to the output we are measuring the 27 volts. because this voltmeter cannot operate the 2 point 4 volts so a 2 point 4 volts I've set this to the maximum which is 27.7V so now I'm reducing the voltage okay 2.23V and then we got 27 volts. so let me reduce it. 2V and still we are given 27 volts and as soon as I go below to the output will change so it can work with the 2 volts and higher to g
