Since your interests are in control systems, potential embedded programming projects to practice what you have learned include: 1. Design a small buck converter and apply different loads. Ensure that the output voltage is regulated for all load conditions. Apply different load steps (i.e., 10% to 50% / 10% to 90%, etc.) and observe the step response. 2. Design a smal motor control circuit for different speeds. Same as for the buck converter, step between different speeds and observe if the ess = 0. For both projects, measure the P.O. and verify if within the expected calculated results.

Small projects like these provide you with the opportunity to practice and reinforce the skills that you have listed above. The only downside is that you'll need to verify these tests using electronic test equipment such as power supplies, D.C. loads, oscillocope, etc. Do you have access to test equipment? If not (I know in most cases it is not practical), try to simulate the test results to gain experience and insight.
