Let's review the project to identify potential issues or improvements:

Power Connections: Ensure that all ICs have their power pins connected. For the NE555P, connect $IC3$ :VCC to the positive voltage rail and $IC3$ :GND to ground. Do the same for SN74LS47DR and SN74LS90N parts: Connect $U1$ :VCC and $U2$ :VCC to the positive voltage rail and $U1$ :GND and $U2$ :GND to ground. Connect $IC1$ :VCC and $IC2$ :VCC to the positive voltage rail and $IC1$ :GND and $IC2$ :GND to ground.
Connections for Counters and Display: Ensure that the SN74LS90N counters ( $IC1$ and $IC2$ ) are correctly connected to your 7-segment display drivers ( $U1$ and $U2$ ), and that the outputs from these drivers drive the appropriate segments of the 7-segment displays ( $D1$ and $D9$ ).
Clock Source: An astable multivibrator circuit using the NE555P ( $IC3$ ) might be needed if you want to provide a clock signal to the SN74LS90N counters. You'd need resistors and capacitors for this configuration which are currently missing from the project.
Reset and Control Pins: Ensure that you are managing reset and other control pins on the ICs ( $IC1$ , $IC2$ , $U1$ , and $U2$ ) so they operate as expected.
Current Limiting Components: Consider adding current-limiting resistors for LEDs to avoid damage. Ensure resistors are in series with each segment of your 7-segment displays ( $D1$ and $D9$ ).

To proceed effectively, let me know if you need guidance on how to implement these elements in your design!

Para crear un contador de 0 a 99, necesitas conectar los componentes existentes de manera que los dos

SN74LS90N

actúen como contadores y los dos

SN74LS47DR

como decodificadores para los displays de 7 segmentos

- Connect $U1:a$ to $D1:a$ .
- Connect $U1:b$ to $D1:b$ .
- Connect $U1:c$ to $D1:c$ .
