Does anyone have a simple schematic of how to connect the MQ-2 to an MKR1010. I understand there is a 5v/3.5v issue, and that a resistor may solve the problem, but what value of resistor, and where to place it in the circuit? Would really appreciate a schematic . . . thank you in advance. William …

Can I use the 5v power supply on the MKR1010?
