  • Arduino: R-2R: Setting the Signal Amplitude

    I'm back again with the resistor DAC on an Arduino Uno as a simple audio generator. I'm not clear how I came to do so many blogs on it, but this is going to be the last one. Here's the latest sketch with commands for setting the output level as well as…
  • Arduino: R-2R; "A Sweep is as Lucky, as Lucky Can Be..."

    I'm back with the test sketch and I've implemented a frequency sweep. This starts at 20Hz and continuously changes the frequency until it arrives at 20kHz where it starts all over again. The sweep is linear because that was what was easy to do (normally…
  • Arduino: R-2R: Setting the Output Frequency

    I've made a bit more progress. I now have my test code connected to the SCPI parser. That was very easy to do: I simply copied their generator example, took out the lines specific to the chip they were using, and adapted it slightly to calculate the table…
  • Arduino: R-2R: "We Interrupt This Programme..."

    More on the R-2R ladder as a DAC. This time some work on the firmware. What I'm doing here is the reverse of what happens when we digitize a signal; at regular intervals I have to come up with the value for the waveform at that moment in time rather than…
  • Arduino: R-2R Experiment

    R-2R sounds like it might be a robot from the Star Wars universe (a ladder robot, maybe?), but in electronics it's the name of a resistor network that can be used to make a DAC (digital-to-analogue converter). I'm going to try doing just that with an…
  • Cool LED Displays: Boost That LED!

    Cool LED displays. I don't have a lot of time at the moment, but wanted to do something [I did vote for it, after all] so I've thrown together this - a simple bit of experimenting with an Arduino. Rather than just light an LED, I thought I'd make…
  • DIY Test Equipment: The Di-o-Matic, a Simple Diode Tester [Arduino]

    I really should be doing other things, but I can't resist doing another quick piece of DIY Test Equipment. Again I'm going to post it here in my blog. I haven't worked it up into a polished piece of equipment - it isn't even really finished - instead…
