• 4 digit Up counter module
• Count increments in each clock pulse
• Can be used with motion sensor to count the movement
• Easy to use
• Works on 5V DC

• Johnson counter module using CD4017
• Device can be controlled using Arduino
• LED runs on each clock pulse given to control pin
• Speed can be adjusted by controlling the frequenzy of clock pulse
• Works on 5V DC

• Connector b/w 32-bit serial-in parallel-out shift register module and 7-digit seven segment display module
• Option provided to assemble AMS1117 voltage regulator IC
• Operating voltage 5V

• Input voltage : 9 - 12V DC
• ESP-12F based IOT module which will give 5V / 9V outputs from five digital pins of ESP-12F
• 5V outputs can be used to control TTL / CMOS ICs
• Output will be 5V if the jumper is conncted across COM and 5V
• Similarly, output will be 9V if the jumper is connected across COM and Vin
