Scoping a simple H bridge, and rambling about my motor driver ideas. 

Really good example of showing use of the oscilloscope. Don't worry about video setup for now. Even if you have more cameras, you should to switch cameras in say OBS studio, or record everything, then later cut in some editing software. Aside video, then you need to think about audio, so one day perhaps radio microphone or just long wire with lapel mic. Or whatever. Things can go very complicated very soon if you want mimic real video studio.

For this DC motor, regenerative braking is difficult to implement because when you switch off, it continues to produce voltage as if another (less than) 12V battery is in parallel with first one, just disconnected negative part. So, in order to brake, you need additional capacitance where you will store extra energy. On your current setup, you can't clearly see, but if you use some flywheel, then you can observe currents for longer time. Whole braking circuit should has separate PWM module, so that does not brake when you throttle down, but only when you want. So, in the case of regenerative braking, you need some sort of boost drive connected to motor as generator and convert falling voltage into something useful. Or re-charging battery, or as spare energy source for next running cycle as a boost energy source.

Thanks for your tutorials. Can you please do an I2C, SPI and CAN tutorial..
