I wanted to make an oscillator out of a cd40109be chip so i looked up some tutorials on how to do it, i followed the tutorials and made sure i got everything right. but when i plunged a speaker in to the output and to ground nothing happened, so i used an LED but still nothing. I'm using a 9v battery to power the circuit on a breadboard and i got the chips from texas instruments via amazon. i am new(ish) to electronics so I'm probably doing something wrong, any ideas? thanks! heres some pictures of the circuit (there is also more information after the pictures):
The red alligator clip is going from the output of the inverter into the positive input of the speaker and the white alligator clip is going to ground and is connected to the negative input on the speaker (the speaker is an Adafruit 3inch speaker) heres the tutorial i followed: http://hackaday.com/2015/02/04/logic-noise-sweet-sweet-oscillator-sounds/
