Arduino comme programmeur atmega328P

-

bonsoir à toutes et à tous,

après avoir réalisé quelques montages à base d'une carte arduino uno, je voudrais programmer l'atmega328p seul.
pour ce faire, j'utilise une uno dans laquelle je transfère le croquis arduinoisp.
ensuite, je suis les indications suivantes : https://www.arduino.cc/en/tutorial/arduinotobreadboard
j'ai utilisé la configuration minimale et malheureusement, j'obtiens le message d'erreur suivant :
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x66
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x66
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x66
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x66
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x66
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xe0
erreur lors de la gravure de la séquence d'initialisation.

j'ai placé un condensateur de 10µf entre la masse et la borne reset de l'uno sans succès, j'obtiens toujours le même message d'erreur.

j'ai regardé à gauche et à droite sur le net et je ne parviens pas à passer le cap de cette étape.

pouvez-vous m'aider ?

un grand merci d'avance.

caways

Arduino Uno + KTY81/210 temperature sensor

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
