I'm about to work on my very first project using arduino (I'm just about to buy one next week), and one of our professor says that we can only upload a program or sketch in an Arduino Uno Board for approximately 8 times. He also added that if we're using a clone version, it'll can only last for 2 sketch uploads. Is this true or is he bluffing? Thank you in advance.
He's talking complete and utter gibberish. To quote from the ATMega328P datasheet:
- High Endurance Non-volatile Memory Segments
- 32KBytes of In-System Self-Programmable Flash program Memory
- 1KBytes EEPROM
- 2KBytes Internal SRAM
- Write/Erase Cycles: 10,000 Flash/100,000 EEPROM
- Data Retention: 20 years at 85°C/100 years at 25°C(1)
- Optional Boot Code Section with Independent Lock Bits
- In-System Programming by On-chip Boot Program
- True Read-While-Write Operation
- Programming Lock for Software Security
So you have at least 10,000 uses out of it before it starts to go flakey.
