9. Connect a 100-ohm resistor to each LED and have this go to the ground rail. 10. Now have a wire come from the following Arduino pins: pin 2 to the green LED, pin 3 to a yellow LED and finally red to pin 4. 11. Now that’s the circuit all set up, it’s now time to ...
On my Arduino Nanos, I always use a 100 Ω series resistor and one IR LED 😀.Minimal CPU clock frequencyFor receiving, the minimal CPU clock frequency is 4 MHz, since the 50 µs timer ISR (Interrupt Service Routine) takes around 12 µs on a 16 MHz ATmega. The TinyReceiver, ...
