Hey Guys -
Working on a project where I am using an Arduino Nano to control 7 pairs of LEDs in a limited space. My draft build used some spare yellow LEDs which had a forward voltage of 1.8-2.2V each so obviously attached each pair to a pin with a resistor without issue. Wanting to use white LEDs for final build, I've found that they are 3.0V each where the supporting 5V cannot light a 6V pair.
Purchasing 5mm White LEDs which are 2.5V (or lower) would be an easy fix, but can't find any. Space is very limited so don't have space for 7 boost converters. I've considered using a 6V supply, but also need to power the other components including SSD1306 OLED, a servo, DHT22, rotary encoder, & piezo buzzer.
Any suggestions? Thanks!
