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?
I'll gladly take any help and thank you beforehand.
