@pebke Ok, probably a normal breadboard issue. I think you are using one of these

@pebke Maybe I am getting forgetful, but the version I am aware of has no 'circuit' unless you are changing clock freq. As far as breadboard, for so...

@pebke Glad you got it working, now we know another way to do it at the extra cost of a shield but simpler?

@inq So... are you saying there is a physical "motor" inside that little thing???? One of many Also see Arduino docs at To get the e...

@poundsand NOT trickery, just a common mistake.

@poundsand Do you have the batteries disconnected? If not you are reading the charger output, not the battery voltage.

@inq IIRC, the 5MP camera pushes the AI-Thinker board too far and the facial recognition code was crippled at least for a while. There are several ver...

@kd9wzz Bill the wizard behind @dronebot-workshop produced a video (eye candy) and article (actual info) in his blog about how to build a linear power...

@poundsand 4 18650's in series is either 12.8V or 14.8V depending on chemistry. The former is LiFePO4 (like the 7.2kWh bank I have) or LiIon for the l...

@inq I just had a quick look at the video and immediately noticed that the camera moved whenever Bill took a picture. This is easily fixed by moving t...

@inq I have not seen the video yet, but I can answer one question. All of the serialization methods mentioned in points 2 & 3 are available on the...

@pebke Try this video. You do NOT need the shield, and you use the regular Arduino IDE. Also check out Ralph Bacon, he has 2 videos. I have not watche...

@pebke Since I have no idea what you are doing, this is a bit of a guess. Everything is fine until a 'read' is issued and the result of that is not ...

@john40131 If I understand correctly you are currently using a NANO, and you are wondering if you can replace it with a NANO that has WiFi? The answer...

@poundsand The charger I have is 120A and it is purchased. It's actually an inverter/charger. The lithium fires were a different chemistry than what...
