A four digit UP counter module designed using CD4026 ICs which can be used to count from 0 to 9999. Count will increment in each LOW to HIGH pulses applied at the CLK input of counter module. Module can be used to count motion easily by connecting a PIR motion sensor directly to the module. No programming required.
7 digit seven segment display module using 4511 IC which will help you to display 7 digit numbers using microcontrollers or Arduino boards. Negative and dot point options are provided so that you will get – symbol at the left end seven segment display. Dot point can be displayed at any digit.
Connector module (Yellow module only) between 32-bit serial-in parallel-out shift register module and 7-digit seven segment display module
Connector module between 32-bit serial-in parallel-out shift register module and 7-digit seven segment display module which will simplifies the connection between these two modules so that we could easily display our desired value on the 7-digit seven segment display from Arduino or ESP-12F IOT module.
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. You can control your devices like electric bulbs from Android applications through this module. Screw terminal output interfacing is also provided for 5V / 9V digital outputs.
This module will help you to make LED flashers of different speeds by varying the value of R1, R2 and C1. Leave POT1 and R2 unconnected. POT1 is parallel to R1 and POT2 is parallel to R2. Only one from each set need to be connected. R1 is 10K. This module can be used for generating clock pulses for Johnson counters, ring counters. digital clocks etc.

Read the blog on LED flasher / Astable multivibrator module using 555 timer to get the detailed explanation of module.
A simple voltage regulator module using 7805. This module can be used to provide stabilized 5V supply to TTL circuits and microcontrollers.
- Assembled Voltage regulator module
Here, we are using 7805 as the voltage regulator. 7805 will give stabilized 5V output. Replacing 7805 by 7808, we can get stabilized 8V output.
