I have a couple of those modules and for testing just used a straight piece of wire cut to length for 915 MHz. Eventually I will use the u.fl connect...

It depends where the rotor is located with respect to the stator. The rotor will be attracted to the stator pole and the motor will need more current ...

I have a Siglent and love it. Rigol makes quality products also. Can't go wrong with either.

I don't follow why temp sensor 2 has to be less than temp sensor 1 for the fan to turn on. Here is some code to get you started. You could use a soli...

You can look at the code to see what is being done in the begin method. I normally just start with a working example which always has xxx.begin() meth...

I said use a voltmeter but you would want to use adc input to measure voltage and calculate in software the inductance.

With a voltmeter across the inductor you have to measure the change in current so you will end up making two measurements the current, voltage at time...

@graham410 I don't see the @@symbols when I look at the code in github. You get that from copy and pasteing from the browser into your editor. Better...

Hello Graham, here are some examples for the OLED. Just choose the example for your display size.

I don't know what you mean by DV voltage ripple. When a power line frequency is rectified it is not flat there is some ripple left over from the line ...

First try this example located at : Adafruit_AM2320/examples/basic_am2320/basic_am2320.ino Always try to start with working code. Add a little of y...

Hello Graham, Remove the semi-colons from the #include and #define statements.

You can probably just get small H bridges and mount them besides the nano. If you have room for a uno you should be able to find small H bridges that ...

Radio energy can turn on transistors if the field is strong enough or near enough. For the purpose of seeing if it is interference if you can try sepa...

Robotics is definitely a journey I would like to join you on. I liked your answers to the questions/comments above. I have so many projects that I wan...
