+<h4><strong>2.4 Observe the operation of a microcontroller circuit board</strong></h4>
+<p1> I used another Oscilloscope of the same brand to test the votage of the microcontroller</p1>
+<h4>Step1.  Conduct a functional check</h4>
+<p1>Following the same steps above and this one does not have any overcompensate problem.</p1>

+<h4> Step2. Adjust all the settings below:</h4>
+<p1> &nbsp&nbsp- Adjust the coupling mode to direct current</p1>

+<h4> Step3. Clamp the ground wire to the ground wire of the nRF82540. Hook the signal wire to the pinheader port which is connected to nRF82540's VCC port.</h4>

+
+<h4> Step4. The votage signal is okay！Because one grid is 5V and the voltage line is at one grid position above the level line, the voltage is a constant 5V.</h4>

       <h2> IndividualAssignment_My PCB </h2>
       <p>   My PCB is going to use the nRF82540 chip with an IMU embedded in it, so the extra components I will use are a LED strip and a sound module in potential. It is also always helpful to add a switch and LED on your PCB for basic testing.</p>
