As a tool it's less functional than a $15 amazon logic probe which can do the same thing, but I get that's not really the point. Here's a tip though, the standard recommendation is no abrasive methods for cutting FR4 board as the dust is carcinogenic. The gold standard is shears but that's a bit unrealistic for hobbyists. For tiny boards like this you can cut them with trauma shears, which are really cheap from the usual places and really useful for all kinds of jobs. That said, I've been cutting copper clad with a hacksaw for years and I ain't dead yet.
You are correct, and it is mentioned on the blog post on the website for this project that the diodes may be unnecessary, but they were a fun way to teach about diodes and what they do, as well as a way to further protect components. As @brocktechnology mentioned, it is good practice though, and LEDs alone do not react well with reverse voltage. Thank you for taking the time to comment and informing us all who reads it. You are greatly appreciated.
ok. you got me. I got tht switch test HAAA that was a good one! because I work on the slide switch circuit. Now do I keep the same 1k resistor with mine?? I do have a green led I a salvaged off a old light. so I'm work out the Ohms law and find out how to run the circuit and take a measurements oooo and i know we can do it with any color led for the record. in just wanted to know about the resistor values with the different motor values. I'm missing something here🤔
=248.5ohm cs my power supply or do I say battery supply is 8.97V... its still Power or Power supply??? hmmm Power is =Watts?? but batteries have Wh to deliver to the load help me understand tht part.... ok so I took avg of my voltages 3 times =4.96V with no load/.02mA =248ohms Ha the relationship between voltage and and these resistor is strange. if I go down just one mm how do I say tht..ahh I'd I go down just one tenth minus .01 off of a volt my OMHs value goes down by .50. thts half?? strange.. hm I love tho1🧐
It doesn't matter too much what size resistor you use. In question #3 on the "Electronics Project: A Simple Switch Circuit" page, I go into detail on how to figure a resistance value for an LED. In the example I was using a red LED, and was using a forward voltage drop of 2.1V for the red LED. For your green LED you can generalize your calculation and use 2V as the forward voltage drop - it won't make much of a difference, but will make calculations a little easier. Hope this helps! Here's the link to that page: motbots.com/electronics-project-a-simple-switch-circuit/#Q3_How_do_we_know_what_size_resistor_to_use_in_our_circuit
@@ashantimundy7603 You can say either power or power supply, it doesn't matter. Yes, the units of power is in watts (W). To explain watt-hours (Wh), let's use an example. If a battery provided 100 Wh of energy, and you powered a load for 1 hour, then 100 W of power was used by the load. To calculate this, the power in watts (P) is proportional to the energy (E) in watt-hours, and inversely proportional to the time in hours (t): P=E/t
