Step 7Test Circuit
This is a single LED version of the circuit. Not especially tidy, but it is a prototype, and follows the circuit diagram from step 7.
You can also see from the power supply that only 24mA is being drawn, compared with the 30mA if the LED was connected normally.
From the third image containing two LEDs, it appears that both LEDs are of the same brightness. However very quickly, the direct driven LED becomes warm quickly giving good reason to PWM.
