1. As indicated in the DK450's example schematics above, the 5V charger does not include the resistors(R1,R2, R3) and capacitor(C2) needed in a "normal circuit without DK450", since the DK450 is already optimized for 5V regulation. 2. As I'd like to 'adjust' the output voltage up...
Ok so now we are ready make the practical example for this tutorial. Here’s the circuit schematics. We will use a potentiometer, at the master, to control a servo motor at the slave. And vice versa, we will use a push button, at the slave, to control a LED at the ...
