Help with rocket launch controller build - Raspberry Pi Forums

i building rocket launch controller. far have launch sequence working when press 'button.' counts down 10 , fires correct led @ end of countdown. have key switch attached board though , want ot launch when key switch on. want led2 on if switch on , led3 on if switch off indicate 'armed' status of controller. know next nothing python , have scrapped code far several tutorials , others' builds of similar projects. code: select all from gpiozero import led, button time import sleep signal import pause subprocess import popen led = led(17) led2 = led(27) led3 = led(22) button = button(2) armswitch = button (4) led2.on() while true: button.wait_for_press() led2.off() print ('countdown sequence initializing. ignition in...') popen(["flite -t 'countdown sequence initializing. ignition in'"], shell=true) sleep(4) in range(0,10): print (10 - i) popen(["flite -t '" + str(10 - i) +&qu

[SOLVED]Clock Set mode issue - capacitive sensors

SPI devices (LCD, nRF24L01) NOT working together - Raspberry Pi Forums

hey guys! i've been lurking around here lot of time, , want build something, need help. i'm building wireless system monitoring temperature , humidity. use rpi base receiving messages nrf24l01 , 2 arduino's sending wirelessly measurements using nrf24l01 , dht22. on rpi side, use pcd8544 displaying measurements. it's working displaying other messages cpu temperature , date/time testing. used texy's code following thread: viewtopic.php?f=32&t=9814 nrf24l01 on rpi side works using blavery's code , library ( viewtopic.php?f=45&t=85504 ) , have received measurements sent arduinos. when try them work together, lcd display works, , seems nrf device "hangs" , not receive until reboot rpi. think use same spi device , confused. 2 devices on rpi side use different spi ces wired gpio pins. so, don't have problem there. maybe it's library issue? help. it's appreciated. hector p.s. tell me post code if needed. wanted keep post s

Arduino + SD card + RTC + NFC : possibile far funzionare tuto insieme?

ciao e tutti, vi chiedo una dritta. mi stavo chiedendo se è possibile creare una cosa del genere con arduino. - prendo una cosa con attaccato un portachiavi nfc e lo leggo. - chi lo prende ha un suo tag nfc che lo identifica e lo leggo. - salvo queste due info + l'orario su un file sd - rifaccio la procedura contraria quando ripongo l'oggetto e salvo questi nuovi dati su una riga della sd. era per un datalogging su chiavi di autoveicoli (2)... accettasi altri consigli, basta che siano più semplici e funzionali possibili. ma è possibile far coesistere tutto ciò su una scheda arduino? sd e rtc sì, perchè esiste lo shield apposito per il datalogging, ma aggiungere un pn532 nfc ? grazie. mi sembra di capire che rtc usi i2c , quindi mi occupa a4 e a5, mentre il problema sarebbe che mi si sovrappongono le connessioni tra sd car reader ( un modulo stand alone, non shield) e nfc pn532 ... c'è soluzione ? oppure potrei usare un arduino collegato ad nfc

sensore di temperatura e luminosità e LCD

salve, sono nuovo su questo forum, appena iscritto. poche settimane fa ho comprato il mio primo arduino starter kit, ho cercato ad apprendere le basi per la programmazione di arduino, ma per me è ancora complicato scrivere un programma non avendo le basi del linguaggio di programmazione. non se questo è il posto giusto dove pubblicare il mio post, e mi scuso se sbaglio. allora in pratica vorrei realizzare un piccolo sistema per rilevare la temperatura e la luminosità dell'ambiente, su internet e altri siti ho cercato progetti simili e ho visto diversi modi e sketch ma nessuno va bene per il mio caso, o forse gli sketch che ho visualizzato non erano corretti per il mio progetto. comunque io utilizzo un sensore di temperatura ds18b20 della dallas, collegato al piedino analogico a0, e una fotoresistenza collegata al piedino analogico a1, ho collegato bene il mio display lcd 16x2 ad arduino, poi vorrei utilizzare un pulsante che in pratica premendolo sul display venga visuali

Welches Roboter-Kit mit Arduino verwenden..?

hallo zusammen, meine langfristige idee ist es ein kleines autonomes (outdoor) roboterfahrzeug zu basteln. jetzt suche ich schon seit einiger zeit nach einem für arduino passenden roboter-kit. der markt ist relativ unübersichtlich und offensichtlich kurzlebig. wobei mir lego oder fischertechnik etwas zu empfindlich ist. im buch "arduino workshops isbn: 978-3-86490-106-5 wird auf ein model pololu rp5 verwiesen. den bausatz gibt es inzwischen nicht mehr zu kaufen. jedenfalls finde ich nichts mehr. im buch "roboter bauen mit arduino: die anleitung für einsteiger (galileo computing) broschiert - 27. oktober 2014" isbn: 978-3836229418 wird auf den link http://botmakers.de verwiesen. der link ist inzwischen tot. interessant finde ich "makeblock" (http://www.exp-tech.de/makeblock-starter-robot-kit-v2-0-blue-with-electronics). sieht sehr umfangreich aus, wird aber wohl wenig mit arduino zusammen verwendet. es gibt natürlich auch den arduino roboter http://ard

Home-made 10W RGB LED driver?

hi, i want control 10 pcs. of 10w rgb leds @ 12v,  including being able change color of each led seperately, preferably @ high speed. i'm thinking can control them on i2c bus several pca9685, each giving me 16 pwm outputs. but cannot draw current chip, else can do? essentially want amplify 5v pwm output. since each channel r,g,b might have different maximum voltages, i'm planning provide constant 12v, 11v , 8v vdc power source. so, perhaps 5v pwm output serve signal high-speed transistor, resulting in respectively 12v, 11v or 8v in pwm form? is design? there better way? if supply constant current not need specify voltage, taken cair of automatically. therefore don't need amplify pwm voltage, use pwm turn on or off constant current drive. this typical constant current drive, parts shown not drive 10w.
