 Before you seek to actually test your circuit, please get verification to proceed from the class channel on discord by posting a clear picture of everything. There are MANY moving parts, and especially as we have our first exposure, it is best to insert as many quality control checks as possible to ensure the greatest chances of mistakes are mitigated. Before you seek to actually test your circuit, please get verification to proceed from the class channel on discord by posting a clear picture of everything.
