Of course the relationship between analogValue and analogWrite to the mosfet is not linear and has to be determined more thoughtfully, for example wit...
@will good idea. I can take a few TMP36 sensors and spread them around the front element retainer of my scope, hook them up in parallel, take the aver...
@will Once the dew point [temperature] (DPT) is calculated using the reported temperature (T) and relative humidity, then the delta between the DPT an...
Generally speaking the ideal imaging location is where the skies are the least polluted. This coincides with a lack of all services, but internet can ...
Here is an article on how to calculate dew point. For simplified cases it proposes: Td = T - ((100 - RH)/5.) Here is an online calculator. ...
@will Thanks, I will.
Thanks. I have an I2C board coming along with the display unit already. It would have been good if TinkerCAD had an I2C board to save us from all that...
DHT22, sorry, the humidity and temperature sensor. Eventually, rather than taking action on one element, action should be taken on the result of an ...
At the moment I have limited success in programming a circuit to respond to temperature change using TinkerCad. Once I fully understand, and can make ...
@will I see, and I think you had told me that before. [1] Sensor sends pertinent data to the microcontroller. [2] microcontroller decides what dut...
@madmisha Thanks a lot. I will certainly look into the SHT31. It looks like it has a couple of ports and that it might need a housing of its own. Ye...
@will I am sure that you are right. But if the outputs are either high or low, how will you tell the MOSFET to allow more voltage to pass through?
@madmisha Thanks for the valuable information. My astro-imaging rig has a stick-PC onboard it and the stick-PC runs all the software and hardware. I...
