Nov yog qhov project me me lom zem uas kuv tau ua thaum dhuav. Tom qab ntawd kuv tau txais ntau dhuav thiab ua qhov kev qhia no. Kuv piav qhia ntu uas xav tau, cov txheej txheem, thiab txheej txheem ua mov ci. Tus so yog nyob ntawm koj.

Koj yuav tsum tau:

1. tus LM339, lossis LM393 sib piv IC 2. ob lub xim sib txawv LEDs 3. ob lub LED resistors ~ 300ohm rau 1k hauv tus nqi 3. piezo buzzer (tsis hloov pauv/hais lus) 4. 4 zoo ib yam "tus nqi siab" resistors, txog 5-10k lossis yog li 5. 1 "tus nqi qis" tus tiv thaiv, qhov chaw nyob nruab nrab ntawm 20 thiab 600 ohms 6. Lub khob cij thiab qee qhov ua. 7. Lub hwj chim. AFAIK LM339 tuaj yeem tswj tau txhua yam txog li 14V. Tab sis koj yuav xav tau yam tsawg kawg ntawm kwv yees li 3V los tsav cov LEDs thiab piezo zoo 'nuff. Ntau dhau qhov hluav taws xob thiab koj yuav ua rau lub Circuit Court puas tsuaj uas koj tab tom ua haujlwm. Cov roj teeb yuav ua tau zoo. Ob peb lub pob alkaline khawm lossis ib leeg lithium npib ntawm tes yuav ua tau zoo. 8. Kwv yees li kaum feeb ntawm lub sijhawm pub dawb.
