Arduino Osc

By modulating the period of highs, we can have different average values and this allows us to control the voltage output to a particular device. Yes, the voltage can also be controlled by a potentiometer but a microcontroller’s digital output can only produce …

HD44780 2×16 Dot Matrix LCD

Lcd Banner

Bought this at Ebay for only RM10 including shipping. This came all the way from China, hence why it is so cheap. Took around two weeks to arrive and here it is. Apparently a paper box is too costly but thank God it arrived in one piece. The connector shown does not come with the LCD, I bought it separately so …
