Building the circuit on a breadboard and writing code for it …
↓↓↓ Complete description, time index and links below ↓↓↓
In video number two (that was published first) we did a rough design for (amongst other things) the DAC circuit for the analog control input of the motor driver (link below). Now it’s time to actually build that circuit and write some code for it.
We start off by soldering two required breakout boards, revisit the circuit’s schematic, and then have a look at the circuit on a breadboard. After that we go through some rounds of incremental coding and tests, until we’re sure everything works.
00:00 Intro – the more you know the more questions you have
00:35 Soldering – breakout boards (DAC & terminal block)
03:45 Circuit – just an overview (details see part 2)
09:53 Breadboard – Arduino, digital isolator, DAC, terminals
10:57 Code 1 – it’s basically doing nothing
11:57 Test 1 – output voltage safe when powering up?
13:54 Code 2 – actually using the DAC to output voltages
21:37 Test 2 – DAC correctly outputs the desired voltages?
22:48 Code 3 – setting DAC voltage by percent motor power
31:01 Test 3 – voltages dead/full ahead/astern & stop correct?
32:36 Test 4 – over-/undershoots when changing DAC output?
34:11 Wrap-up – next we connect the motor driver, bye
