I can't seem to understand what all the hate comments are about. The only slight issue I'm having is reliablility (getting incomplete messages), but this maybe a faulty device or software on my behlaf

Great video. Would love to see one where you read from Bluetooth too. Actually I have a project, totally new to Arduino, where I want to use an SD card shield to log readings, and BT to read them over to my phone. It’s important too, it’s a septic tank where I plan on using sensors for distance, and not have to remove the top anymore and look down there!

@shader26 2 жыл бұрын

@@Motorsport_N54F01 hi. No. I mean I am in process of figuring it out. I made a prototype with Arduino Uno and a HM-10 “shield” and got it working great. But when I wired up the “final product” where I use an Arduino Pro Mini and HM-10 it’s been problematic. Telephone BLE apps aren’t getting replies, not for AT commands, nor to talk to the Arduino sketch program. Too hard to detail here but am trying many things now to see if it is as dumb as CR and LF messing up the hm-10 sending commands (defined in the sketch) further to the Arduino. Like I said, prototype works great.

@davebacknolaliki1452 Жыл бұрын

Note that this is completely okay for logic signals as he is doing here that you’re simply reading but this is not something you would want to use if you are providing power to a load. Since the current through a load may vary, so will the resistance in parallel with “R2” which will throw your voltage divider off. A voltage divider is not regulated and you will effectively be making a variable voltage at the point your supplying that voltage from. Also in higher current applications you’re wasting all of that power as heat, nothing that we would really see here with this setup. Voltage dividers are also used on the gate side of a mosfet for noise reasons when using it as a switch or for DC biasing when using it as an amplifier.
