Hi everyone,
I am doing project involving photodynamic therapy on cancer cell lines using led.For that purpose i have to create arrays of led (i.e 96 LEDs in 8*12 fashion) so that equal current flows in all branches of led and there will be no current fluctuation.... i have seen many circuits with LM317 but i needed one with transistor....so any sort of answers will be highly appreciated...I'll be waiting for reply....!!!....Thanks....!!!
