Assembly of IR transmitter kit is very straight forward and all components are through-hole. You can see the label and images printed on the circuit board and assemble the components accordingly.
Step 1: Fix resistors.
Step 2: Fix ceramic capacitors. Code for 0.1uF is 104 and code for 0.001uF is 102.
Step 3: Fix 8 pin IC socket. This socket is used for placing NE555 timer.
Step 4: Fix 2 pin screw terminal and SPDT switch. The screw terminal is used for connecting 6V-9V battery.
Step 5: Fix IR LED.
You can bend the IR LED as shown on the image below. This will give better performance. There is nothing hard and fast rule for this. The basic idea is that the IR LED and the IR receiver on the counter module should be in the line of sight(in a straight line).
Your IR transmitter module is now ready. Connect a 9V battery on to the module and use it with the counter module. See on the image below how the battery is connected. Red wire is for positive and Black wire is for negative.
On the image below, you can see how the counter module and transmitter have been placed facing each other.
The following image shows how you place the 2 digit object counter and IR transmitter:

3 Digit Digital Object Counter ASSEMBLED Kit With Infrared Transmitter And Laser ModuleUS $14.95
This is 3 digits digital object counter kit for electronics beginners and hobbyists. It is the upgraded version of our previous 2 digits and 3 digits object counter.
You can use this 3 digits digital object counter for counting objects or people entering in a room. It can be used by engineers for learning about digital counters.
This DIY digital object counter works with VS1838 infrared receiver and photoresistor and there are three seven segment displays displaying numbers from 0 to 999. An IR transmitter is directed towards the VS1838 infrared receiver of the counter module and objects are moved between the two modules. Each time an object passes between the two modules, the seven-segment displays show increment in numbers from 0 to 999.
