Ground:
Pin 1 is connected to ground.
VCC:
Pin 8 is connected to the positive supply voltage. This voltage must be at least 4.5 V and no greater than 15 V. It’s common to run 555 circuits using four AA or AAA batteries, providing 6 V, or a single 9 V battery.
Output:
Pin 3 is the output pin. The output is either low, which is very close to 0 V, or high, which is close to the supply voltage that’s placed on pin 8. The exact shape of the output — that is, how long it’s high and how long it’s low, depends on the connections to the remaining five pins.
Trigger:
Pin 2 is the trigger, which works like a starter’s pistol to start the 555 timer running. The trigger is an active low trigger, which means that the timer starts when voltage on pin 2 drops to below one-third of the supply voltage. When the 555 is triggered via pin 2, the output on pin 3 goes high.
Discharge:
Pin 7 is called the discharge. This pin is used to discharge an external capacitor that works in conjunction with a resistor to control the timing interval. In most circuits, pin 7 is connected to the supply voltage through a resistor and to ground through a capacitor.
Threshold:
Pin 6 is called the threshold. The purpose of this pin is to monitor the voltage across the capacitor that’s discharged by pin 7. When this voltage reaches two thirds of the supply voltage (Vcc), the timing cycle ends, and the output on pin 3 goes low.
Control:
Pin 5 is the control pin. In most 555 circuits, this pin is simply connected to ground, usually through a small 0.01 µF capacitor. (The purpose of the capacitor is to level out any fluctuations in the supply voltage that might affect the operation of the timer.)
Reset:
Pin 4 is the reset pin, which can be used to restart the 555’s timing operation. Like the trigger input, reset is an active low input. Thus, pin 4 must be connected to the supply voltage for the 555 timer to operate. If pin 4 is momentarily grounded, the 555 timer’s operation is interrupted and won’t start again until it’s triggered again via pin 2.

Item Condition
New
A brand-new, unused, unopened, undamaged item in its original packaging (where packaging is applicable). Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. See the seller's listing for full details.
Payment
We require that all customers bidding on auction or purchasing Buy It Now items have a PayPal account and are in compliance with all eBay’s and PayPal’s account requirements.
Only payments through PayPal will be accepted.
Shipment of item will one occur until payment has been received.
Immediate payment will be required on all Buy It Now sales. Payment within 2 days of an auction end date will be required. If payment is not received by the within 4 days, an unpaid item case will be opened. Upon the closing of an unpaid claim, the item will be relisted for sale and the existing sale will be cancelled.
We are physically located in Colorado and thus must charge Colorado residents a 2.9% sales tax.
Shipping
SHIPS FROM COLORADO, USA
Items typically ship the same day as when the payment has been received. Any items where the payment is received on Saturday afternoon or Sunday may be shipped on Monday morning or the following business day.
All shipments will be made though USPS and will have a tracking number available.
Since we are centrally located within the US, shipping times typically take only 2 days. However in rare cases shipping time may take up to 5 days depending on location within the lower 48 states. Shipping outside the lower 48 states may take longer.
All orders exceeding a combined price of 0 will require a signature upon delivery.
Packages shipped to an address incorrectly provided by the buyer will be subject to cancellation or a reshipping charge. Be sure that the address you provide or your PayPal address is correct before making a purchase.
