hanga he pwm motopaika tere kaiwhakahaere

Ko nga microcontrollers pera i a Arduinos he huarahi pai ki te whakahaere i nga kaupapa hiko ritenga.
Kia aroha mai, ko te nui rawa o te putanga o te titi matihiko ko te 40 mA, kaore e ranea ki te whakakaha i te nuinga o nga motuka.
Koinei te waahi ka taea e te whakangungu motuka motuka te uru mai.
Engari he utu nui enei mea ki te hoko me te tuku noa koe ki te whakahaere i etahi motuka, ina koa ka whakauruhia e koe ki tetahi kaupapa.
Ko te kaiwhakahaere tere ngawari ka whakamahi i te tohu whakarereke whanui puihi hei whakarite i te tere o te motuka.
Ka taea te hanga i tenei tohu e tetahi titi whakahurihuri whanui puihi i runga i te Arduino.
No reira me whakamahi tatou i te hiko hiko o waho (
Pērā i te mōkihi pākahiko)
Iahiko whakawhiti whakawhiti.
He rite tenei ki te ara iahiko transistor i runga i te parepare relay, engari kua whakarereketia e matou.
I whakauruhia e ahau he LED tohu tohu ki runga i te putanga.
I roto i tenei kaupapa ka whakaatu ahau ki a koe me pehea te hanga i a koe ake motuka motuka ngawari.
He ranunga tenei o nga tohutohu a Jason Poel Smith 'Me pehea te whakarite i te whakangungu rakau mo to moroiti-mana' tohutohu, a ka whakaranu ano e ahau te whakangungu rakau taraiwa.
Tena koa pooti mo te Remix 2. 0 Contest!
Anei nga rawa me nga taputapu e hiahiatia ana mo tenei kaupapa.
Rauemi: 2x momo transistor (pērā i te tip31a)
2x IN4001 diode 2x1 k sfp parenga 2x100 SFP parenga 2 x LED te tae o taau e pai ai 2x1 wahine 1x4 wahine 1x Pūhiko tūhono
No.
Ma te tapahi i nga rawa rua ki te haurua me te whakamahi i te hoahoa, ka taea e koe te hanga i tetahi ara iahiko noa.
Nga Utauta: Me timata ma te whakapiri i nga whakawhiti hiko e rua ki runga i te PCB, te rino me te kaitapa waea whakapiri waea tihorea nga kutukutu ngira ihu pli.
Waiho he mokowhiti i waenganui i nga waahanga e rua hei waahi mo etahi atu waahanga.
Kaua ano e kuti nga mata.
I muri i te hono atu ki te transistor, ka taea e koe te tapahi i te mata.
Kia mahara ki te whakaputanga titi transistor i runga ake nei kia kore e he te hononga.
Kia pai ake ai te mohio ki te ara iahiko me te pehea e mahi ai, he pai pea te mahi tauira ara iahiko ki runga i te papa parāoa i te tuatahi.
Wea ki runga upoko wahine iti 1x2.
Hei tauira, ka taea e koe te whakamahi i nga pito wiri (
I te mutunga ka hurihia e au enei mea e rua.
Mo te hononga ngawari ake.
Ano, waiho he mokowhiti i waenga i te upoko me te transistor mo etahi atu waahanga.
Solder the diode on the pre-circuit board in front of the subtitle. Connect the
diode to the head as shown in figure 3rd. This
will prevent the motor from delivering high

Tapahia te mata paraharaha me te mata parenga

koe e kuti i nga mata, waea waea ranei

E hanga ana matou i nga motuka hiko e 2!
Kia
taea e koe te hono atu ki te hiko o to hiahia (
ki te ngaohiko me te hiko o te motini me te MCU
ka hono atu ki te 9 v, 12 v ranei te urunga hiko

te turanga (titi 1)
Transistor ki te 1 o nga titi e wātea ana i runga i te upoko nui
mahia tenei mahi i runga i te toenga parenga, hono atu ki te titi whakamutunga e wātea ana
tenei upoko nui mo te whakauru / putanga
Tuhonohia te pine PWM kua paiherea me te whakamahi i te titi hiko hei putanga, te whakaurunga o te hiko o te hiko

transmitter leads and LED leads.
I use the blue wire.
Connect the positive wire to the solder joint closest to the silver strip on the diode.
Look at the pictures for reference as this part can get tricky.
Do this for both groups of headers.
This is where you remember the resistance pair you made.
Select the motor connection head pin and find out what transistor the LED near the head pin is connected.
After completion, connect the wire from the remaining solder joints on the te upoko pine me te hono atu ki te kaikohi (pin 2)
te transistor kua hono te LED

ma te tuku i te whakahau tuhi ki te
papa o te Ardu ki
te takaro ki nga nama me te waehere kia pai ai te whakamahi i te mana whakahaere moroiti
, me whakarite he putanga PWM me te whakarite i te putanga kia rite ki te tere e hiahiatia ana
Ki te kore koe e mohio ki te mahi i tenei, kimihia te tauira waehere e whakahaere ana i te LED ka huri i te waehere kia rite ki o
hiahia
