This is the oscilloscope I am using in this lesson: [Affiliate Links]

In this video I show you how to turn on the Digital to Analog Converter (DAC) that is on the Arduino R4 Wifi. I show you how to use it and program it to get true analog signals out of the arduino.

Brilliant! I haven't got an R4 yet so can't join in but your explanations are simple and clear. Roll on the op amp!

Hi Paul, I'm loving this series. I've had a PC based oscilloscope (Hantek 6022BE) for a few years now and really haven't had much use for it till now, so it's great to learn how to put it to use. Also, I spoke to my CFO (wife) and she's given me permission to contribute to your great cause again. Keep up the good work and thanks again.

Thank you Paul for passing along these more advanced lessons. I always find them helpful .. Love the idea of integrating the OpAmp as you mentioned . They have always been a weak topic in my knowledge bank .

Lovely to have woken up to this video. Thanks heaps Paul. You are legend! The sheer passion of your videos give something special to every subject you indulge in. God bless 🎉

Great discussion as always! Since these live sessions are a chance to jump ahead I would like to see one showing how you would control something using the R4's wifi capability. For example - turning the built in LED located on the R4 on/off remotely from a computer or phone. Thanks.

This is a very useful video. Please keep the live streams coming.

Excellent analog video. I really like the scope. My scope has the I2C RS232 SPI decoder, which is handy for MODBUS stuff. ✨ The sin-wave example is nice. Thank you Paul. I like the live-streams and op-amps is a great jewel subject. . 💎

I would like to catch the next livestream, but I enjoyed watching this one after the fact, though. 👍 😄

Trigger on the falling edge of the sawtooth to solve the jitter. Note the jitter may be noise picked up by the scope probes rather than a noisy DAC output. You won't see stair steps using increments of 1 no matter how much you slow it down because the steps are 1/255th of each ramp and you simply can't see that resolution on the scope screen.

Op amps are exciting.

@michaelpell2104 5 месяцев назад

Very useful

@michaelpell2104 5 месяцев назад

Maybe use op amp as filter. Produce 60 to 10k warble with DAC. Make op amp only let 2k - 3k thru kind of thing. Absolutely love your courses. Thank you.

Thanks

@paulmcwhorter 5 месяцев назад

Wow, really appreciate that. It is a big encouragement, thank you for the generosity.

Hi Paul, how to make a PID control with the output of the PID (MV) with a value range of 0 to 5 vdc? please advise, thank you

@TheUnofficialMaker 5 месяцев назад

NICELY DONE! Is your compound highly automated, if not,might be a cool ongoing project! Yes, the op amp live stream sounds great. PS: You should get a RC boat with cam!!

@paulmcwhorter 5 месяцев назад

Don't have a RC boat, but do have a nice drone which makes some awesome video of the area around our compound.

@freddyveza 5 месяцев назад

Hey Paul! Great lesson, thanks. Can you please recommend a simpler oscilloscope for hobbyists or enthusiasts? I think getting this one for my use case would be like getting a bazooka to kill a fly

@paulmcwhorter 5 месяцев назад

Freddy, this one is the simple one. It is not as complicated as it looks.
