I have an existing board that I had designed for me that controls motorized displays and music in a clock. It uses 4 ics (lm324n op amp, 74hct4040 logic counter, 74hct flip flop and a 555 timer). I don't have a schematic of the circuit, but I have posted a picture explaining the connects.
The operation is as follows: the clock chimes and counts the hour which is monitored though wires from the electronic clock speaker. After a short delay, the left and right animation motors are powered for a time (controlled by a pot). A relay is energized that turns on an electro mechanical device that starts a mechanical music movement. The circuit resets until the next chime hour. There is a override button to test operation between chimes. The supply voltage is 6vdc from a wall transformer. The motors are display (hankscraft) type and draw low amperage.
This is a prototype I was going to use in floor and mantle clocks that I build.
This circuit board was too expensive to build ( although it 's been working in my prototype floor clock for 15 years) In recent years, there has been a few new things that I would like to try , like an Arduino controller. The gearmotor technology is miniaturized to the point where I have designed a small enough electro mech. actuator that could fit into my mantle clock. Also I would like to interface with sound files, led lighting. I have installed the new led light strips in my floor clock recently.
I would like some help with the circuit design and arduino program (sketch). I would like to ultimately produce a circuit board that I can use the atmega chip. I am not an electronic techie so
any help would greatly be appreciated!
