Please only write in C only for the Arduino Uni, no Arduino functions(such as pinMode, delay).

I've only gotten this far, I don't know if it'll work.

Circuit I: Blinking an LED START - ----- - - setup() configure pin D7 as output ----------- turn on LED (set pin D7) delay 1 s turn off LED (clear pin D7) loop() delay 1s void setup() { DDRO = ob 1000 DDDD Vord loop() { POR TD =bl0000000; - delay_ms(1000); PORTD = b 00000000; - delay_ms(1000); 3
