Hello, my friends and me have been doing a Carbon Monoxide Detector for a group project for school. After making the board and soldering it we found out it didn't work and that all the other components only received like 1.4 volts, another friend measured the MQ7 and said it consumed 100mA and said it was leaving the other components with no power. What could the problem be in this case?

You will need to supply details of whatever the MQ7 is and how it is powered.
Need to be aware for example that the maximum current for an Arduino pin is around 20mA.
What is the power you are applying to Vcc....??
