Nov 10, 2015 · Here is 10 output LED sequencer. After the last LED is illuminated, the circuit is reset. This circuit is build around readily available, low cost components - a 555 and decade counter CD4O1 7. The timer IC NE555 is wired as an astable multivibrator that produces 6Hz clock at its output pin 3. The 4017 is a CMOS decade counter with 10 outputs. There is a problem, though, in switching the gate pulses that come out of the PAiA 4780 sequencer, since this is the only module in the PAiA line that has a non-standard voltage output (typically +13 to +15 Volts). This is higher than the maximum allowable input of IC3, which is +6 V.

Essentially, they’re basic analogue 8 step sequencers based on a 4017 decade counter, offering note on/off/reset per step. There’s an internal clock provided by a 40106 with quite a wider range, and there’s an option for externally clocking, although you’ll have to get quite close to the input voltage to clock it.

Jan 18, 2011 · Note that the 4017 counter will not deliver much current, and so the LED current is set to about 6mA using a 1.5K resistor in series. For more current, you could use transistors on each output as shown in the drawing above, (10 Channel LED Sequencer). But some of the newer bright LEDs are fairly bright at 6mA.

Dec 25, 2020 · The solution was simple: use logic gates to gate all clock signals to the 4017. Using this approach, multiple clock sources could be used (astable multivibrators [square wave oscillators], pushbutton switch) and the sequencer could be paused at any time for tuning of each step’s CV (Control Voltage).

Hi i saw your instructible and was very interesting, i was wondering if you could help. I have just recently built a pwm synthesiser usingg lm358 dual opamps, i am also building a sequencer circuit built with 4017 and 555 for the clock, i am just unsure how to combine the two circuits together so i have sequencer synth... any tips would be great.

The two 4017 decade counters control the 10 rows and 10 columns so that one LED is selected depending on the output of the decade counters. The LED circuit is drawn showing 25 LEDs and 10 transistors but can be expanded up to a 100 by using sucessive stages of the 4017 counters. Remember - these two signals are being fed to a CD4081 AND gate, which doesn't have nearly the delay that the 4017 does (the 4017 has a bit more plumbing for the internal signals to run through). So, because, during that brief instant, both signals are high, the AND gate says "I spy!" furthermore, each part has 32 presets (together with the famous "r" button), a rate control (1/2 , 1/4, 1/8 , 1/16), start step and end step offset knobs + a slice and a gate button:-gate button: if the current step in the first (sample offset) sequencer is 0 it won´t play the loop at this moment. (required for some presets.)
Each time the clock input pin of 4017 IC detects a rise in voltage (from low to high), it turns off the current output and turns on the next sequential output. This swapping of outputs which looks like the LEDs are chasing each other, continues until the last LED and then the output resets back to the first LED. Applications

An LED chaser circuit (ring counter) is a repeating sequencer usually made by combining a clock with a counter. The clock can be any of several types including discrete components such as astable multivibrator, inverter, logic gate, a pushbutton or a dedicated timer IC such as a NE555.The counter can be any of several types including 4-bit, 8-bit, decade or shift registers, depending on the ...Jun 10, 2012 · Plc 1. page 0 FS = first scan T1 = ST2 ⋅ A AST1 C*B ST3 T2 = ST1 ⋅ B T1 T3 = ST3 ⋅ ( C ⋅ B ) T3 T4 = ST2 ⋅ ( C + B ) T4 ST1 = ( ST1 + T1 ) ⋅ T2 + FS B T2 ST2 = ( ST2 + T2 + T3 ) ⋅ T1 ⋅ T4 ST2 C+B ST3 = ( ST3 + T4 ⋅ T1 ) ⋅ T3ST2 A T1ST1 B Automating Manufacturing Systems T2ST3 C B with PLCs T3ST2 C T4 BT2 (Version 4.7, April 14, 2005) ST1 ST1 T1 first scanT1 T4 ST2 ST2 Hugh ...
