It's hard to know what you're talking about since we can't see the devices you're specifying, but the Arduino RP2040 and BLE models are not based on A...

[/quote] On another related issue, I got the idea today that I could start doing the videos with a mask on. I had to wear one all day at the hospita...

@dronebot-workshop Wow ! I hope your run of Bad Luck ends soon.

@dbwfred You shouldn't be impressed with it as it's just an example of the structure you'll eventually need. The overall flow will be more or les...

@dbwfred Q2 - partly Here's a simple outline of what you'd need as the sketch for this activity. I am not familiar with the braking system nor th...

@dronebot-workshop Wow ! Hope you make a fast and pain-free recovery. Sounds like you need to consider switching to extra high-tread sneakers or a...

@dbwfred G'day cobbler, welcome to the forum. We'll throw another Arduino on the barbie for ya :)

@jettedlikeshek Check the wiring and all your solder joints first; that's free and doesn't require any time waiting for the goods to arrive. I ca...

@jettedlikeshek OK, I agree with @zander and @davee that your problem is the battery. It can only supply about 500mA for an hour or so IIRC. So, ...

@jettedlikeshek It's difficult to answer your question about power supply when you haven't indicated any power source for either the transmitter or...

@jettedlikeshek Perhaps you could provide a drawing of your wiring to help us understand your circuits.

No, I changed it a couple of months ago. My previous signature was "I had a psychic girlfriend but she left me before we met."

Anther lesson to learn is that when you are looking at your own diagrams, wiring and sketches, your mind tends to see what you MEANT as oppose to what...

I'm glad it was that easy (it rarely happens that way) :) The reason that it worked is because the ULN2003 has an inverter on each pin and that's wh...
