I Have Googled the 555 timer and was trying to use two with reverse polarities but the second timer cannot start in the off position so it resulted in a failure .. and no this is actually an invention i am working on ...also can you stick around please im from the caribbean and not much electronic experts here you guys are all i have .. maybe you can send a datasheet on what i should do pleasee .. i bought proteus so i can keep up with you . I may be completely wrong i have no idea what im doing please reccomend the best thing for me to do
this question is relevant if not crucial
it's the wattage or
volt--amp or
any power specs of the motor
it's about the 9V 6LF22 or other https://www.powerstream.com/9V-Alkaline-tests.htm being able to start and run it
Even the tiniest motor can lift a few ounces if you gear it down enough. The question then is how fast you have to lift the weight, since force times speed determines the power the motor must provide.
Okay Guys ill buy that motor but can someone please send a schematic of how i should design the circuit to acheive the 5 second intervals please ... i have no idea what should i use the 555 , the H bridge ... capacitors resistors?
what you need to add to the schm.** is +/- square wave half cycles of duration 10s each e.g. 20s(50mHz(milli-Hertz)Sq.Wv.) that triggers another 1-shot timer of 5-s at zero crossing of the 1-st one
or set up a binary control based on mod-2 2bit counter driven by 2.5s pulse train and encode your FW NOP BW NOP from 00 01 10 11 ...
or other ... (such. as discriminating sine or 3-wave to 3-level detector as -- when above 1/3-rd of +A =forward inside ±1/3A =rest below -1/3A =reverse) . . . e.c. . . .
