I'm a beginner and, as an exercise, I'm building a digital clock using without a microcontroller. The main IC that I'm using is a 4026, which counts and converts do 7-segment led format.
The leds in the 7-segment glow very dimly. I'm reading the 4026 datasheet, and trying to make sense of it. The diagram (reproduced below) seem to imply - if I'm reading correctly - that I would need a transistor for each one of the leds in de 7-segment display. My display is common-cathode.
Since I'm building a digital clock, this would mean that I'd need 6*7=42 transistors, which seem like overkill for such a simple project. I also saw some similar projects on the internet that don't use the transistors.
Should I put all the transistors in the circuit? If not, then how can I make the LED glow more brightly?
