Aquarium Timer Schematic and Board Layout Main aquarium timer circuit board schematic. CD4541 Timing Calculations. To change the clock timing of the CD4541 ic. R1 and C1 set the oscillator frequency and R2 should be >10K and approximately 2 times the resistance of R1. The CD4541 in my circuit is running at approximately 36hz and is outside of the range of the specified 1kHz to 100kHz ... Aquarium Fish Feeder Timer Controller Circuit | Homemade ... As shown in the proposed fish feeder timer controller circuit, N1, N2 and N3, N4 are the four NAND gates from the IC 4093, configured as flip flop timer stages. N1, N2 forms the 7 second delay timer, the period may be adjusted and set with the help of the 1M pot, identically N3, N4 is wired up as the second 5.2 second delay generator stage. AquaCont – Aquarium Control – Circuit Wiring Diagrams The power supply needed by the main board is 5V, while the relays board requires 12V; the different source power was useful in granting the protection of the microcontroller and his circuits from overvoltage and short circuit on the 220V. AquaCont Aquarium Control Electronics Lab The power supply needed by the main board is 5V, while the relays board requires 12V; the different source power was useful in granting the protection of the microcontroller and his circuits from overvoltage and short circuit on the 220V. Two optocouplers are utilized for that purpose ensuring the isolation of the different voltages. Automatic Aquarium Feeder: 7 Steps (with Pictures) Hi Paul, I was trying to make the aquarium feeder as per your given instruction. But I couldn't get the idea of feeding 12VDc in to the clock circuit as shown in your post. I have assembled the remaining things like Relay & 555 timer. but I'm not sure how to trigger Pin 2 of 555 timer for a fraction of second if we use this as monostable timer. Timed LED Aquarium Lighting Project | All About Circuits Timed LED Aquarium Lighting Project Reply to Thread. Discussion in 'The Projects Forum' started by luxsphinx, Aug 10, ... Since that circuit would only turn the white LEDs on an then off instead of switching to the blue, would using a SPDT relay solve this? ... With the Arduino you simply buy the main board (like 30 bucks) and plug it into your ... Types of Timer Circuits with Schematics and its Working ... 1. Long Duration Timer. This timer circuit is designed to switch on a 12 V load in a solar powered installation for a preset period at the press of a button. When the period has expired a latching relay disconnects both the load and the controller circuit from the 12 V supply.
